Sets the trace name. The trace name appears as the legend item and on hover.

Determines whether or not this trace is visible. If 'legendonly', the trace is not drawn, but can appear as a legend item (provided that the legend itself is visible).

Determines whether or not an item corresponding to this trace is shown in the legend.

Sets the reference to a legend to show this trace in. References to these legends are 'legend', 'legend2', 'legend3', etc. Settings for these legends are set in the layout, under `layout.legend`, `layout.legend2`, etc.

Sets the legend rank for this trace. Items and groups with smaller ranks are presented on top/left side while with 'reversed' `legend.traceorder` they are on bottom/right side. The default legendrank is 1000, so that you can use ranks less than 1000 to place certain items before all unranked items, and ranks greater than 1000 to go after all unranked items. When having unranked or equal rank items shapes would be displayed after traces i.e. according to their order in data and layout.

Sets the legend group for this trace. Traces and shapes part of the same legend group hide/show at the same time when toggling legend items.

If there are less than 20 points and the trace is not stacked then the default is 'lines+markers'. Otherwise, 'lines'.

Assigns id labels to each datum. These ids for object constancy of data points during animation. Should be an array of strings, not numbers or any other type.

Sets the layer on which this trace is displayed, relative to other SVG traces on the same subplot. SVG traces with higher `zorder` appear in front of those with lower `zorder`.

Sets the x coordinates.

If an array of string, the items are mapped in order to the this trace's (x,y) coordinates. If trace `hoverinfo` contains a 'text' flag and 'hovertext' is not set, these elements will be seen in the hover labels.

Sets the positions of the `text` elements with respects to the (x,y) coordinates.

Template string used for rendering the information text that appear on points. Note that this will override `textinfo`. Variables are inserted using %{variable}, for example "y: %{y}". Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-format/tree/v1.4.5#d3-format for details on the formatting syntax. Dates are formatted using d3-time-format's syntax %{variable|d3-time-format}, for example "Day: %{2019-01-01|%A}". https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format for details on the date formatting syntax. Every attributes that can be specified per-point (the ones that are `arrayOk: true`) are available.

Sets hover text elements associated with each (x,y) pair. If a single string, the same string appears over all the data points. If an array of string, the items are mapped in order to the this trace's (x,y) coordinates. To be seen, trace `hoverinfo` must contain a 'text' flag.

Determines which trace information appear on hover. If `none` or `skip` are set, no information is displayed upon hovering. But, if `none` is set, click and hover events are still fired.

Template string used for rendering the information that appear on hover box. Note that this will override `hoverinfo`. Variables are inserted using %{variable}, for example "y: %{y}" as well as %{xother}, {%_xother}, {%_xother_}, {%xother_}. When showing info for several points, 'xother' will be added to those with different x positions from the first point. An underscore before or after '(x|y)other' will add a space on that side, only when this field is shown. Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-format/tree/v1.4.5#d3-format for details on the formatting syntax. Dates are formatted using d3-time-format's syntax %{variable|d3-time-format}, for example "Day: %{2019-01-01|%A}". https://github.com/d3/d3-time-format/tree/v2.2.3#locale_format for details on the date formatting syntax. The variables available in `hovertemplate` are the ones emitted as event data described at this link https://plotly.com/javascript/plotlyjs-events/#event-data. Additionally, every attributes that can be specified per-point (the ones that are `arrayOk: true`) are available. Anything contained in tag `<extra>` is displayed in the secondary box, for example "<extra>{fullData.name}</extra>". To hide the secondary box completely, use an empty tag `<extra></extra>`.

Sets the hover text formatting rulefor `x` 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'By default the values are formatted using `xaxis.hoverformat`.

Sets the hover text formatting rulefor `y` 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'By default the values are formatted using `yaxis.hoverformat`.

Assigns extra meta information associated with this trace that can be used in various text attributes. Attributes such as trace `name`, graph, axis and colorbar `title.text`, annotation `text` `rangeselector`, `updatemenues` and `sliders` `label` text all support `meta`. To access the trace `meta` values in an attribute in the same trace, simply use `%{meta[i]}` where `i` is the index or key of the `meta` item in question. To access trace `meta` in layout attributes, use `%{data[n[.meta[i]}` where `i` is the index or key of the `meta` and `n` is the trace index.

Assigns extra data each datum. This may be useful when listening to hover, click and selection events. Note that, 'scatter' traces also appends customdata items in the markers DOM elements

Sets a reference between this trace's x coordinates and a 2D cartesian x axis. If 'x' (the default value), the x coordinates refer to `layout.xaxis`. If 'x2', the x coordinates refer to `layout.xaxis2`, and so on.

Sets a reference between this trace's y coordinates and a 2D cartesian y axis. If 'y' (the default value), the y coordinates refer to `layout.yaxis`. If 'y2', the y coordinates refer to `layout.yaxis2`, and so on.

Only relevant in the following cases: 1. when `scattermode` is set to 'group'. 2. when `stackgroup` is used, and only the first `orientation` found in the `stackgroup` will be used - including if `visible` is 'legendonly' but not if it is `false`. Sets the stacking direction. With 'v' ('h'), the y (x) values of subsequent traces are added. Also affects the default value of `fill`.

Only relevant when `stackgroup` is used, and only the first `groupnorm` found in the `stackgroup` will be used - including if `visible` is 'legendonly' but not if it is `false`. Sets the normalization for the sum of this `stackgroup`. With 'fraction', the value of each trace at each location is divided by the sum of all trace values at that location. 'percent' is the same but multiplied by 100 to show percentages. If there are multiple subplots, or multiple `stackgroup`s on one subplot, each will be normalized within its own set.

Set several traces linked to the same position axis or matching axes to the same alignmentgroup. This controls whether bars compute their positional range dependently or independently.

Set several traces linked to the same position axis or matching axes to the same offsetgroup where bars of the same position coordinate will line up.

Set several scatter traces (on the same subplot) to the same stackgroup in order to add their y values (or their x values if `orientation` is 'h'). If blank or omitted this trace will not be stacked. Stacking also turns `fill` on by default, using 'tonexty' ('tonextx') if `orientation` is 'h' ('v') and sets the default `mode` to 'lines' irrespective of point count. You can only stack on a numeric (linear or log) axis. Traces in a `stackgroup` will only fill to (or be filled to) other traces in the same group. With multiple `stackgroup`s or some traces stacked and some not, if fill-linked traces are not already consecutive, the later ones will be pushed down in the drawing order.

Only relevant when the axis `type` is 'date'. Sets the period positioning in milliseconds or 'M<n>' on the x axis. Special values in the form of 'M<n>' could be used to declare the number of months. In this case `n` must be a positive integer.

Only relevant when the axis `type` is 'date'. Sets the alignment of data points on the x axis.

Only relevant when the axis `type` is 'date'. Sets the base for period positioning in milliseconds or date string on the x0 axis. When `x0period` is round number of weeks, the `x0period0` by default would be on a Sunday i.e. 2000-01-02, otherwise it would be at 2000-01-01.

Only relevant when the axis `type` is 'date'. Sets the period positioning in milliseconds or 'M<n>' on the y axis. Special values in the form of 'M<n>' could be used to declare the number of months. In this case `n` must be a positive integer.

Only relevant when the axis `type` is 'date'. Sets the alignment of data points on the y axis.

Only relevant when the axis `type` is 'date'. Sets the base for period positioning in milliseconds or date string on the y0 axis. When `y0period` is round number of weeks, the `y0period0` by default would be on a Sunday i.e. 2000-01-02, otherwise it would be at 2000-01-01.

Has an effect only if in `marker.color` is set to a numerical array. In case `colorscale` is unspecified or `autocolorscale` is true, the default palette will be chosen according to whether numbers in the `color` array are all positive, all negative or mixed.

• cauto
  Parent: data[type=scatter].marker
  Type: boolean

  Determines whether or not the color domain is computed with respect to the input data (here in `marker.color`) or the bounds set in `marker.cmin` and `marker.cmax` Has an effect only if in `marker.color` is set to a numerical array. Defaults to `false` when `marker.cmin` and `marker.cmax` are set by the user.

• cmax
  Parent: data[type=scatter].marker
  Type: number

  Sets the upper bound of the color domain. Has an effect only if in `marker.color` is set to a numerical array. Value should have the same units as in `marker.color` and if set, `marker.cmin` must be set as well.

• cmid
  Parent: data[type=scatter].marker
  Type: number

  Sets the mid-point of the color domain by scaling `marker.cmin` and/or `marker.cmax` to be equidistant to this point. Has an effect only if in `marker.color` is set to a numerical array. Value should have the same units as in `marker.color`. Has no effect when `marker.cauto` is `false`.

• cmin
  Parent: data[type=scatter].marker
  Type: number

  Parent: data[type=scatter].marker
  Type: subplotid

  Sets a reference to a shared color axis. References to these shared color axes are 'coloraxis', 'coloraxis2', 'coloraxis3', etc. Settings for these shared color axes are set in the layout, under `layout.coloraxis`, `layout.coloraxis2`, etc. Note that multiple color scales can be linked to the same color axis.

  • dtick
    Parent: data[type=scatter].marker.colorbar
    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

  • labelalias
    Parent: data[type=scatter].marker.colorbar
    Type: number or categorical coordinate string

    Replacement text for specific tick or hover labels. For example using {US: 'USA', CA: 'Canada'} changes US to USA and CA to Canada. The labels we would have shown must match the keys exactly, after adding any tickprefix or ticksuffix. For negative numbers the minus sign symbol used (U+2212) is wider than the regular ascii dash. That means you need to use −1 instead of -1. labelalias can be used with any axis type, and both keys (if needed) and values (if desired) can include html-like tags or MathJax.

  • nticks
    Parent: data[type=scatter].marker.colorbar
    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'.

  • tickangle
    Parent: data[type=scatter].marker.colorbar
    Type: angle
    Default: 'auto'

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 whether or not markers and text nodes are clipped about the subplot axes. To show markers and text nodes above axis lines and tick labels, make sure to set `xaxis.layer` and `yaxis.layer` to 'below traces'.

Determines whether or not gaps (i.e. {nan} or missing values) in the provided data arrays are connected.

Sets the area to fill with a solid color. Defaults to 'none' unless this trace is stacked, then it gets 'tonexty' ('tonextx') if `orientation` is 'v' ('h') Use with `fillcolor` if not 'none'. 'tozerox' and 'tozeroy' fill to x=0 and y=0 respectively. 'tonextx' and 'tonexty' fill between the endpoints of this trace and the endpoints of the trace before it, connecting those endpoints with straight lines (to make a stacked area graph); if there is no trace before it, they behave like 'tozerox' and 'tozeroy'. 'toself' connects the endpoints of the trace (or each segment of the trace if it has gaps) into a closed shape. 'tonext' fills the space between two traces if one completely encloses the other (eg consecutive contour lines), and behaves like 'toself' if there is no trace before it. 'tonext' should not be used if one trace does not enclose the other. Traces in a `stackgroup` will only fill to (or be filled to) other traces in the same group. With multiple `stackgroup`s or some traces stacked and some not, if fill-linked traces are not already consecutive, the later ones will be pushed down in the drawing order.

Sets the fill color. Defaults to a half-transparent variant of the line color, marker color, or marker line color, whichever is available. If fillgradient is specified, fillcolor is ignored except for setting the background color of the hover label, if any.

• start
  Parent: data[type=scatter].fillgradient
  Type: number

  Sets the gradient start value. It is given as the absolute position on the axis determined by the orientiation. E.g., if orientation is 'horizontal', the gradient will be horizontal and start from the x-position given by start. If omitted, the gradient starts at the lowest value of the trace along the respective axis. Ignored if orientation is 'radial'.

• stop
  Parent: data[type=scatter].fillgradient
  Type: number

  Sets the gradient end value. It is given as the absolute position on the axis determined by the orientiation. E.g., if orientation is 'horizontal', the gradient will be horizontal and end at the x-position given by end. If omitted, the gradient ends at the highest value of the trace along the respective axis. Ignored if orientation is 'radial'.

• type
  Parent: data[type=scatter].fillgradient
  Type: enumerated , one of ( 'radial' | 'horizontal' | 'vertical' | 'none' )

• bgcolor
  Parent: data[type=scatter].fillpattern
  Type: color or array of colors

  When there is no colorscale sets the color of background pattern fill. Defaults to a `marker.color` background when `fillmode` is 'overlay'. Otherwise, defaults to a transparent background.

• fgcolor

• shape
  Parent: data[type=scatter].fillpattern
  Type: enumerated or array of enumerateds , one of ( '' | '/' | '\' | 'x' | '-' | '|' | '+' | '.' )

    Parent: data[type=scatter].hoverlabel.font
    Type: enumerated or array of enumerateds , one of ( 'normal' | 'word caps' | 'upper' | 'lower' )
    Default: 'normal'

    Sets capitalization of text. It can be used to make text appear in all-uppercase or all-lowercase, or with each word capitalized.

  • variant
    Parent: data[type=scatter].hoverlabel.font
    Type: enumerated or array of enumerateds , one of ( 'normal' | 'small-caps' | 'all-small-caps' | 'all-petite-caps' | 'petite-caps' | 'unicase' )
    Default: 'normal'

    Sets the variant of the font.

  • weight
    Parent: data[type=scatter].hoverlabel.font
    Type: integer or array of integers between or equal to 1 and 1000
    Default: normal

    Sets the weight (or boldness) of the font.

• namelength
  Parent: data[type=scatter].hoverlabel
  Type: integer or array of integers greater than or equal to -1
  Default: 15

  Sets the default length (in number of characters) of the trace name in the hover labels for all traces. -1 shows the whole name regardless of length. 0-3 shows the first 0-3 characters, and an integer >3 will show the whole name if it is less than that many characters, but if it is longer, will truncate to `namelength - 3` characters and add an ellipsis.

Do the hover effects highlight individual points (markers or line points) or do they highlight filled regions? If the fill is 'toself' or 'tonext' and there are no markers or text, then the default is 'fills', otherwise it is 'points'.

Only relevant when `stackgroup` is used, and only the first `stackgaps` found in the `stackgroup` will be used - including if `visible` is 'legendonly' but not if it is `false`. Determines how we handle locations at which other traces in this group have data but this one does not. With 'infer zero' we insert a zero at these locations. With 'interpolate' we linearly interpolate between existing values, and extrapolate a constant beyond the existing values.

Sets the calendar system to use with `x` date data.

Sets the calendar system to use with `y` date data.

Controls persistence of some user-driven changes to the trace: `constraintrange` in `parcoords` traces, as well as some `editable: true` modifications such as `name` and `colorbar.title`. Defaults to `layout.uirevision`. Note that other user-driven trace attribute changes are controlled by `layout` attributes: `trace.visible` is controlled by `layout.legend.uirevision`, `selectedpoints` is controlled by `layout.selectionrevision`, and `colorbar.(x|y)` (accessible with `config: {editable: true}`) is controlled by `layout.editrevision`. Trace changes are tracked by `uid`, which only falls back on trace index if no `uid` is provided. So if your app can add/remove traces before the end of the `data` array, such that the same trace has a different index, you can still preserve user-driven changes if you give each trace a `uid` that stays with it as it moves.
