MATLAB Figure Reference: splom Traces

A splom trace is a struct inside fig.data which has type equal to 'splom'. This section lists all of the valid keys that a splom struct can contain.

Splom traces generate scatter plot matrix visualizations. Each splom `dimensions` items correspond to a generated axis. Values for each of those dimensions are set in `dimensions[i].values`. Splom traces support all `scattergl` marker style attributes. Specify `layout.grid` attributes and/or layout x-axis and y-axis attributes for more control over the axis positioning and style.

  • type
    Parent: data[type=splom]
    Type: 'splom'
  • name
    Parent: data[type=splom]
    Type: string

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

  • visible
    Parent: data[type=splom]
    Type: enumerated , one of ( true | false | 'legendonly' )
    Default: true

    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).

  • showlegend
    Parent: data[type=splom]
    Type: boolean
    Default: true

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

  • legend
    Parent: data[type=splom]
    Type: subplotid
    Default: 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.

  • legendrank
    Parent: data[type=splom]
    Type: number
    Default: 1000

    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.

  • legendgroup
    Parent: data[type=splom]
    Type: string
    Default: ''

    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.

      Type: string

      Sets the label corresponding to this splom dimension.

    • name
      Parent: data[type=splom].dimensions[]
      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.

    • templateitemname
      Parent: data[type=splom].dimensions[]
      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`.

      Sets the dimension values to be plotted.

    • visible
      Parent: data[type=splom].dimensions[]

    Examples: 'x', 'y', 'x+y', 'x+y+z', 'all'
    Default: 'all'

    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.

  • hovertemplate
    Parent: data[type=splom]
    Type: string or array of strings
    Default: ''

    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>`.

  • xhoverformat
    Parent: data[type=splom]
    Type: string
    Default: ''

    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`.

  • yhoverformat
    Parent: data[type=splom]
    Type: string
    Default: ''

    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`.

  • meta
    Parent: data[type=splom]
    Type: number or categorical coordinate string

    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.

  • customdata
    Parent: data[type=splom]
    Type: array

    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

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=splom].marker
      Type: boolean
      Default: true

Defaults to `false` when `marker.cmin` and `marker.cmax` are set by the user.

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

      Sets the lower 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.cmax` must be set as well.

    • color
      Parent: data[type=splom].marker
      Type: color or array of colors

      Sets the marker color. It accepts either a specific color or an array of numbers that are mapped to the colorscale relative to the max and min values of the array or relative to `marker.cmin` and `marker.cmax` if set.

    • coloraxis
      Parent: data[type=splom].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.

    • colorbar
      Parent: data[type=splom].marker
      Type: struct containing one or more of the keys listed below.
      • bgcolor

        Parent: data[type=splom].marker.colorbar
        Type: color
        Default: '#444'

        Sets the axis line color.

      • borderwidth
        Parent: data[type=splom].marker.colorbar
        Type: number greater than or equal to 0
        Default: 0

        Sets the width (in px) or the border enclosing this color bar.

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

      • labelalias
        Parent: data[type=splom].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.

        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'.

        Default: 'normal'

        Sets whether a font should be styled with a normal or italic face from its family.

      • textcase
        Parent: data[type=splom].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=splom].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 weight (or boldness) of the font.

    • namelength
      Parent: data[type=splom].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.

  • uirevision
    Parent: data[type=splom]
    Type: number or categorical coordinate string

    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.
