R Figure Reference: layout.yaxis

  • yaxis
    Parent: layout
    Type: named list containing one or more of the keys listed below.
    • anchor
      Parent: layout.yaxis
      Type: enumerated , one of ( "free" | "/^x([2-9]|[1-9][0-9]+)?( domain)?$/" | "/^y([2-9]|[1-9][0-9]+)?( domain)?$/" )

      If set to an opposite-letter axis id (e.g. `x2`, `y`), this axis is bound to the corresponding opposite-letter axis. If set to "free", this axis' position is determined by `position`.

    • automargin
      Parent: layout.yaxis
      Type: boolean

      Determines whether long tick labels automatically grow the figure margins.

    • autorange
      Parent: layout.yaxis
      Type: enumerated , one of ( TRUE | FALSE | "reversed" )
      Default: TRUE

      Determines whether or not the range of this axis is computed in relation to the input data. See `rangemode` for more info. If `range` is provided, then `autorange` is set to "FALSE".

    • autotypenumbers
      Parent: layout.yaxis
      Type: enumerated , one of ( "convert types" | "strict" )
      Default: "convert types"

      Using "strict" a numeric string in trace data is not converted to a number. Using "convert types" a numeric string in trace data may be treated as a number during automatic axis `type` detection. Defaults to layout.autotypenumbers.

    • calendar
      Parent: layout.yaxis
      Type: enumerated , one of ( "chinese" | "coptic" | "discworld" | "ethiopian" | "gregorian" | "hebrew" | "islamic" | "jalali" | "julian" | "mayan" | "nanakshahi" | "nepali" | "persian" | "taiwan" | "thai" | "ummalqura" )
      Default: "gregorian"

      Sets the calendar system to use for `range` and `tick0` if this is a date axis. This does not set the calendar for interpreting data on this axis, that's specified in the trace or via the global `layout.calendar`

    • categoryarray
      Parent: layout.yaxis
      Type: dataframe column, list, vector

      Sets the order in which categories on this axis appear. Only has an effect if `categoryorder` is set to "array". Used with `categoryorder`.

    • categoryorder
      Parent: layout.yaxis
      Type: enumerated , one of ( "trace" | "category ascending" | "category descending" | "array" | "total ascending" | "total descending" | "min ascending" | "min descending" | "max ascending" | "max descending" | "sum ascending" | "sum descending" | "mean ascending" | "mean descending" | "median ascending" | "median descending" )
      Default: "trace"

      Specifies the ordering logic for the case of categorical variables. By default, plotly uses "trace", which specifies the order that is present in the data supplied. Set `categoryorder` to "category ascending" or "category descending" if order should be determined by the alphanumerical order of the category names. Set `categoryorder` to "array" to derive the ordering from the attribute `categoryarray`. If a category is not found in the `categoryarray` array, the sorting behavior for that attribute will be identical to the "trace" mode. The unspecified categories will follow the categories in `categoryarray`. Set `categoryorder` to "total ascending" or "total descending" if order should be determined by the numerical order of the values. Similarly, the order can be determined by the min, max, sum, mean or median of all the values.

    • color
      Parent: layout.yaxis
      Type: color
      Default: "#444"

      Sets default for all colors associated with this axis all at once: line, font, tick, and grid colors. Grid color is lightened by blending this with the plot background Individual pieces can override this.

    • constrain
      Parent: layout.yaxis
      Type: enumerated , one of ( "range" | "domain" )

      If this axis needs to be compressed (either due to its own `scaleanchor` and `scaleratio` or those of the other axis), determines how that happens: by increasing the "range", or by decreasing the "domain". Default is "domain" for axes containing image traces, "range" otherwise.

    • constraintoward
      Parent: layout.yaxis
      Type: enumerated , one of ( "left" | "center" | "right" | "top" | "middle" | "bottom" )

      If this axis needs to be compressed (either due to its own `scaleanchor` and `scaleratio` or those of the other axis), determines which direction we push the originally specified plot area. Options are "left", "center" (default), and "right" for x axes, and "top", "middle" (default), and "bottom" for y axes.

    • dividercolor
      Parent: layout.yaxis
      Type: color
      Default: "#444"

      Sets the color of the dividers Only has an effect on "multicategory" axes.

    • dividerwidth
      Parent: layout.yaxis
      Type: number
      Default: 1

      Sets the width (in px) of the dividers Only has an effect on "multicategory" axes.

    • domain
      Parent: layout.yaxis
      Type: list
      Default: [0, 1]

      Sets the domain of this axis (in plot fraction).

    • dtick
      Parent: layout.yaxis
      Type: number or categorical coordinate string

      Sets the step in-between ticks on this axis. Use with `tick0`. Must be a positive number, or special strings available to "log" and "date" axes. If the axis `type` is "log", then ticks are set every 10^(n"dtick) where n is the tick number. For example, to set a tick mark at 1, 10, 100, 1000, ... set dtick to 1. To set tick marks at 1, 100, 10000, ... set dtick to 2. To set tick marks at 1, 5, 25, 125, 625, 3125, ... set dtick to log_10(5), or 0.69897000433. "log" has several special values; "L<f>", where `f` is a positive number, gives ticks linearly spaced in value (but not position). For example `tick0` = 0.1, `dtick` = "L0.5" will put ticks at 0.1, 0.6, 1.1, 1.6 etc. To show powers of 10 plus small digits between, use "D1" (all digits) or "D2" (only 2 and 5). `tick0` is ignored for "D1" and "D2". If the axis `type` is "date", then you must convert the time to milliseconds. For example, to set the interval between ticks to one day, set `dtick` to 86400000.0. "date" also has special values "M<n>" gives ticks spaced by a number of months. `n` must be a positive integer. To set ticks on the 15th of every third month, set `tick0` to "2000-01-15" and `dtick` to "M3". To set ticks every 4 years, set `dtick` to "M48"

    • exponentformat
      Parent: layout.yaxis
      Type: enumerated , one of ( "none" | "e" | "E" | "power" | "SI" | "B" )
      Default: "B"

      Determines a formatting rule for the tick exponents. For example, consider the number 1,000,000,000. If "none", it appears as 1,000,000,000. If "e", 1e+9. If "E", 1E+9. If "power", 1x10^9 (with 9 in a super script). If "SI", 1G. If "B", 1B.

    • fixedrange
      Parent: layout.yaxis
      Type: boolean

      Determines whether or not this axis is zoom-able. If TRUE, then zoom is disabled.

    • gridcolor
      Parent: layout.yaxis
      Type: color
      Default: "#eee"

      Sets the color of the grid lines.

    • gridwidth
      Parent: layout.yaxis
      Type: number greater than or equal to 0
      Default: 1

      Sets the width (in px) of the grid lines.

    • hoverformat
      Parent: layout.yaxis
      Type: string
      Default: ""

      Sets the hover text formatting rule using d3 formatting mini-languages which are very similar to those in Python. For numbers, see: https://github.com/d3/d3-format/tree/v1.4.5#d3-format. And for dates see: https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format. We add two items to d3's date formatter: "%h" for half of the year as a decimal number as well as "%{n}f" for fractional seconds with n digits. For example, "2016-10-13 09:15:23.456" with tickformat "%H~%M~%S.%2f" would display "09~15~23.46"

    • layer
      Parent: layout.yaxis
      Type: enumerated , one of ( "above traces" | "below traces" )
      Default: "above traces"

      Sets the layer on which this axis is displayed. If "above traces", this axis is displayed above all the subplot's traces If "below traces", this axis is displayed below all the subplot's traces, but above the grid lines. Useful when used together with scatter-like traces with `cliponaxis` set to "FALSE" to show markers and/or text nodes above this axis.

    • linecolor
      Parent: layout.yaxis
      Type: color
      Default: "#444"

      Sets the axis line color.

    • linewidth
      Parent: layout.yaxis
      Type: number greater than or equal to 0
      Default: 1

      Sets the width (in px) of the axis line.

    • matches
      Parent: layout.yaxis
      Type: enumerated , one of ( "/^x([2-9]|[1-9][0-9]+)?( domain)?$/" | "/^y([2-9]|[1-9][0-9]+)?( domain)?$/" )

      If set to another axis id (e.g. `x2`, `y`), the range of this axis will match the range of the corresponding axis in data-coordinates space. Moreover, matching axes share auto-range values, category lists and histogram auto-bins. Note that setting axes simultaneously in both a `scaleanchor` and a `matches` constraint is currently forbidden. Moreover, note that matching axes must have the same `type`.

    • minexponent
      Parent: layout.yaxis
      Type: number greater than or equal to 0
      Default: 3

      Hide SI prefix for 10^n if |n| is below this number. This only has an effect when `tickformat` is "SI" or "B".

    • mirror
      Parent: layout.yaxis
      Type: enumerated , one of ( TRUE | "ticks" | FALSE | "all" | "allticks" )

      Determines if the axis lines or/and ticks are mirrored to the opposite side of the plotting area. If "TRUE", the axis lines are mirrored. If "ticks", the axis lines and ticks are mirrored. If "FALSE", mirroring is disable. If "all", axis lines are mirrored on all shared-axes subplots. If "allticks", axis lines and ticks are mirrored on all shared-axes subplots.

    • nticks
      Parent: layout.yaxis
      Type: integer greater than or equal to 0
      Default: 0

      Specifies the maximum number of ticks for the particular axis. The actual number of ticks will be chosen automatically to be less than or equal to `nticks`. Has an effect only if `tickmode` is set to "auto".

    • overlaying
      Parent: layout.yaxis
      Type: enumerated , one of ( "free" | "/^x([2-9]|[1-9][0-9]+)?( domain)?$/" | "/^y([2-9]|[1-9][0-9]+)?( domain)?$/" )

      If set a same-letter axis id, this axis is overlaid on top of the corresponding same-letter axis, with traces and axes visible for both axes. If "FALSE", this axis does not overlay any same-letter axes. In this case, for axes with overlapping domains only the highest-numbered axis will be visible.

    • position
      Parent: layout.yaxis
      Type: number between or equal to 0 and 1
      Default: 0

      Sets the position of this axis in the plotting space (in normalized coordinates). Only has an effect if `anchor` is set to "free".

    • range
      Parent: layout.yaxis
      Type: list

      Sets the range of this axis. If the axis `type` is "log", then you must take the log of your desired range (e.g. to set the range from 1 to 100, set the range from 0 to 2). If the axis `type` is "date", it should be date strings, like date data, though Date objects and unix milliseconds will be accepted and converted to strings. If the axis `type` is "category", it should be numbers, using the scale where each category is assigned a serial number from zero in the order it appears.

    • rangebreaks
      Parent: layout.yaxis
      Type: list of named list where each named list has one or more of the keys listed below.
      • bounds

        Sets the size of each `values` item. The default is one day in milliseconds.

      • enabled
        Parent: layout.yaxis.rangebreaks[]
        Type: boolean
        Default: TRUE

        Determines whether this axis rangebreak is enabled or disabled. Please note that `rangebreaks` only work for "date" axis type.

      • name
        Parent: layout.yaxis.rangebreaks[]
        Type: string

        When used in a template, named items are created in the output figure in addition to any items the figure already has in this array. You can modify these items in the output figure by making your own item with `templateitemname` matching this `name` alongside your modifications (including `visible: FALSE` or `enabled: FALSE` to hide it). Has no effect outside of a template.

      • pattern
        Parent: layout.yaxis.rangebreaks[]
        Type: enumerated , one of ( "day of week" | "hour" | "" )

        Determines a pattern on the time line that generates breaks. If "day of week" - days of the week in English e.g. 'Sunday' or `sun` (matching is case-insensitive and considers only the first three characters), as well as Sunday-based integers between 0 and 6. If "hour" - hour (24-hour clock) as decimal numbers between 0 and 24. for more info. Examples: - { pattern: 'day of week', bounds: [6, 1] } or simply { bounds: ['sat', 'mon'] } breaks from Saturday to Monday (i.e. skips the weekends). - { pattern: 'hour', bounds: [17, 8] } breaks from 5pm to 8am (i.e. skips non-work hours).

      • templateitemname
        Parent: layout.yaxis.rangebreaks[]
        Type: string

        Used to refer to a named item in this array in the template. Named items from the template will be created even without a matching item in the input figure, but you can modify one by making an item with `templateitemname` matching its `name`, alongside your modifications (including `visible: FALSE` or `enabled: FALSE` to hide it). If there is no template or no matching item, this item will be hidden unless you explicitly show it with `visible: TRUE`.

      • values
        Parent: layout.yaxis.rangebreaks[]
        Type: list

        Sets the coordinate values corresponding to the rangebreaks. An alternative to `bounds`. Use `dvalue` to set the size of the values along the axis.

    • rangemode
      Parent: layout.yaxis
      Type: enumerated , one of ( "normal" | "tozero" | "nonnegative" )
      Default: "normal"

      If "normal", the range is computed in relation to the extrema of the input data. If "tozero"`, the range extends to 0, regardless of the input data If "nonnegative", the range is non-negative, regardless of the input data. Applies only to linear axes.

    • scaleanchor
      Parent: layout.yaxis
      Type: enumerated , one of ( "/^x([2-9]|[1-9][0-9]+)?( domain)?$/" | "/^y([2-9]|[1-9][0-9]+)?( domain)?$/" )

      If set to another axis id (e.g. `x2`, `y`), the range of this axis changes together with the range of the corresponding axis such that the scale of pixels per unit is in a constant ratio. Both axes are still zoomable, but when you zoom one, the other will zoom the same amount, keeping a fixed midpoint. `constrain` and `constraintoward` determine how we enforce the constraint. You can chain these, ie `yaxis: {scaleanchor: "x"}, xaxis2: {scaleanchor: "y"}` but you can only link axes of the same `type`. The linked axis can have the opposite letter (to constrain the aspect ratio) or the same letter (to match scales across subplots). Loops (`yaxis: {scaleanchor: "x"}, xaxis: {scaleanchor: "y"}` or longer) are redundant and the last constraint encountered will be ignored to avoid possible inconsistent constraints via `scaleratio`. Note that setting axes simultaneously in both a `scaleanchor` and a `matches` constraint is currently forbidden.

    • scaleratio
      Parent: layout.yaxis
      Type: number greater than or equal to 0
      Default: 1

      If this axis is linked to another by `scaleanchor`, this determines the pixel to unit scale ratio. For example, if this value is 10, then every unit on this axis spans 10 times the number of pixels as a unit on the linked axis. Use this for example to create an elevation profile where the vertical scale is exaggerated a fixed amount with respect to the horizontal.

    • separatethousands
      Parent: layout.yaxis
      Type: boolean

      If "TRUE", even 4-digit integers are separated

    • showdividers
      Parent: layout.yaxis
      Type: boolean
      Default: TRUE

      Determines whether or not a dividers are drawn between the category levels of this axis. Only has an effect on "multicategory" axes.

    • showexponent
      Parent: layout.yaxis
      Type: enumerated , one of ( "all" | "first" | "last" | "none" )
      Default: "all"

      Default: "all"

      If "all", all tick labels are displayed with a prefix. If "first", only the first tick is displayed with a prefix. If "last", only the last tick is displayed with a suffix. If "none", tick prefixes are hidden.

    • showticksuffix

      Sets the dash style of lines. Set to a dash type string ("solid", "dot", "dash", "longdash", "dashdot", or "longdashdot") or a dash length list in px (eg "5px,10px,2px,2px").

    • spikemode
      Parent: layout.yaxis
      Type: flaglist string. Any combination of "toaxis", "across", "marker" joined with a "+"
      Examples: "toaxis", "across", "toaxis+across", "toaxis+across+marker"
      Default: "toaxis"

Provide multiple font families, separated by commas, to indicate the preference in which to apply fonts if they aren't available on the system. The Chart Studio Cloud (at https://chart-studio.plotly.com or on-premise) generates images on a server, where only a select number of fonts are installed and supported. These include "Arial", "Balto", "Courier New", "Droid Sans",, "Droid Serif", "Droid Sans Mono", "Gravitas One", "Old Standard TT", "Open Sans", "Overpass", "PT Sans Narrow", "Raleway", "Times New Roman".

      • size
        Parent: layout.yaxis.tickfont
        Type: number greater than or equal to 1
    • tickformat
      Parent: layout.yaxis
      Type: string
      Default: ""

      Sets the tick label formatting rule using d3 formatting mini-languages which are very similar to those in Python. For numbers, see: https://github.com/d3/d3-format/tree/v1.4.5#d3-format. And for dates see: https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format. We add two items to d3's date formatter: "%h" for half of the year as a decimal number as well as "%{n}f" for fractional seconds with n digits. For example, "2016-10-13 09:15:23.456" with tickformat "%H~%M~%S.%2f" would display "09~15~23.46"

      Determines where tick labels are drawn with respect to their corresponding ticks and grid lines. Only has an effect for axes of `type` "date" When set to "period", tick labels are drawn in the middle of the period between ticks.

    • ticklabeloverflow
      Parent: layout.yaxis
      Type: enumerated , one of ( "allow" | "hide past div" | "hide past domain" )

      Determines how we handle tick labels that would overflow either the graph div or the domain of the axis. The default value for inside tick labels is "hide past domain". Otherwise on "category" and "multicategory" axes the default is "allow". In other cases the default is "hide past div".

    • ticklabelposition
      Parent: layout.yaxis
      Type: enumerated , one of ( "outside" | "inside" | "outside top" | "inside top" | "outside left" | "inside left" | "outside right" | "inside right" | "outside bottom" | "inside bottom" )
      Default: "outside"

      Determines where tick labels are drawn with respect to the axis Please note that top or bottom has no effect on x axes or when `ticklabelmode` is set to "period". Similarly left or right has no effect on y axes or when `ticklabelmode` is set to "period". Has no effect on "multicategory" axes or when `tickson` is set to "boundaries". When used on axes linked by `matches` or `scaleanchor`, no extra padding for inside labels would be added by autorange, so that the scales could match.

    • ticklen
      Parent: layout.yaxis
      Type: number greater than or equal to 0
      Default: 5

      Sets the tick length (in px).

    • tickmode
      Parent: layout.yaxis
      Type: enumerated , one of ( "auto" | "linear" | "array" )

      Sets the tick mode for this axis. If "auto", the number of ticks is set via `nticks`. If "linear", the placement of the ticks is determined by a starting position `tick0` and a tick step `dtick` ("linear" is the default value if `tick0` and `dtick` are provided). If "array", the placement of the ticks is set via `tickvals` and the tick text is `ticktext`. ("array" is the default value if `tickvals` is provided).

    • tickprefix
      Parent: layout.yaxis
      Type: string
      Default: ""

      Sets a tick label prefix.

    • ticks
      Parent: layout.yaxis
      Type: enumerated , one of ( "outside" | "inside" | "" )

      Determines whether ticks are drawn or not. If "", this axis' ticks are not drawn. If "outside" ("inside"), this axis' are drawn outside (inside) the axis lines.

    • tickson
      Parent: layout.yaxis
      Type: enumerated , one of ( "labels" | "boundaries" )
      Default: "labels"

      Determines where ticks and grid lines are drawn with respect to their corresponding tick labels. Only has an effect for axes of `type` "category" or "multicategory". When set to "boundaries", ticks and grid lines are drawn half a category to the left/bottom of labels.

    • ticksuffix
      Parent: layout.yaxis
      Type: string
      Default: ""

      Sets a tick label suffix.

    • ticktext
      Parent: layout.yaxis
      Type: dataframe column, list, vector

      Sets the text displayed at the ticks position via `tickvals`. Only has an effect if `tickmode` is set to "array". Used with `tickvals`.

    • tickvals
      Parent: layout.yaxis
      Type: dataframe column, list, vector

      Sets the values at which ticks on this axis appear. Only has an effect if `tickmode` is set to "array". Used with `ticktext`.

    • tickwidth
      Parent: layout.yaxis
      Type: number greater than or equal to 0
      Default: 1

      Sets the tick width (in px).

    • title
      Parent: layout.yaxis
      Type: named list containing one or more of the keys listed below.
      • font
        Parent: layout.yaxis.title
        Type: named list containing one or more of the keys listed below.

        Sets this axis' title font. Note that the title's font used to be customized by the now deprecated `titlefont` attribute.

        • color
          Parent: layout.yaxis.title.font
          Type: color
        • family
          Parent: layout.yaxis.title.font
          Type: string

          HTML font family - the typeface that will be applied by the web browser. The web browser will only be able to apply a font if it is available on the system which it operates. Provide multiple font families, separated by commas, to indicate the preference in which to apply fonts if they aren't available on the system. The Chart Studio Cloud (at https://chart-studio.plotly.com or on-premise) generates images on a server, where only a select number of fonts are installed and supported. These include "Arial", "Balto", "Courier New", "Droid Sans",, "Droid Serif", "Droid Sans Mono", "Gravitas One", "Old Standard TT", "Open Sans", "Overpass", "PT Sans Narrow", "Raleway", "Times New Roman".

        • size
          Parent: layout.yaxis.title.font
          Type: number greater than or equal to 1
      • standoff
        Parent: layout.yaxis.title
        Type: number greater than or equal to 0

        Sets the standoff distance (in px) between the axis labels and the title text The default value is a function of the axis tick labels, the title `font.size` and the axis `linewidth`. Note that the axis title position is always constrained within the margins, so the actual standoff distance is always less than the set or default value. By setting `standoff` and turning on `automargin`, plotly.js will push the margins to fit the axis title at given standoff distance.

      • text
        Parent: layout.yaxis.title
        Type: string

        Sets the title of this axis. Note that before the existence of `title.text`, the title's contents used to be defined as the `title` attribute itself. This behavior has been deprecated.

    • type
      Parent: layout.yaxis
      Type: enumerated , one of ( "-" | "linear" | "log" | "date" | "category" | "multicategory" )
      Default: "-"

      Sets the axis type. By default, plotly attempts to determined the axis type by looking into the data of the traces that referenced the axis in question.

    • uirevision
      Parent: layout.yaxis
      Type: number or categorical coordinate string

      Controls persistence of user-driven changes in axis `range`, `autorange`, and `title` if in `editable: TRUE` configuration. Defaults to `layout.uirevision`.

    • visible
      Parent: layout.yaxis
      Type: boolean

      A single toggle to hide the axis while preserving interaction like dragging. Default is TRUE when a cheater plot is present on the axis, otherwise FALSE

    • zeroline
      Parent: layout.yaxis
      Type: boolean

      Determines whether or not a line is drawn at along the 0 value of this axis. If "TRUE", the zero line is drawn on top of the grid lines.

    • zerolinecolor
      Parent: layout.yaxis
      Type: color
      Default: "#444"

      Sets the line color of the zero line.

    • zerolinewidth
      Parent: layout.yaxis
      Type: number
      Default: 1

      Sets the width (in px) of the zero line.
