METHODS

TO_JSON

Serialize the trace to JSON. This method should be called only by JSON serializer.

type

Trace type.

ATTRIBUTES

• a

  Sets the x coordinates.

• a0

  Alternate to `x`. Builds a linear space of x coordinates. Use with `dx` where `x0` is the starting coordinate and `dx` the step.

• asrc

  Sets the source reference on Chart Studio Cloud for `a`.

• atype

  If *array*, the heatmap's x coordinates are given by *x* (the default behavior when `x` is provided). If *scaled*, the heatmap's x coordinates are given by *x0* and *dx* (the default behavior when `x` is not provided).

• autocolorscale

  Determines whether the colorscale is a default palette (`autocolorscale: true`) or the palette determined by `colorscale`. 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.

• autocontour

  Determines whether or not the contour level attributes are picked by an algorithm. If *true*, the number of contour levels can be set in `ncontours`. If *false*, set the contour level attributes in `contours`.

• b

  Sets the y coordinates.

• b0

  Alternate to `y`. Builds a linear space of y coordinates. Use with `dy` where `y0` is the starting coordinate and `dy` the step.

• bsrc

  Sets the source reference on Chart Studio Cloud for `b`.

• btype

  If *array*, the heatmap's y coordinates are given by *y* (the default behavior when `y` is provided) If *scaled*, the heatmap's y coordinates are given by *y0* and *dy* (the default behavior when `y` is not provided)

• carpet

  The `carpet` of the carpet axes on which this contour trace lies

• coloraxis

  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

• colorscale

  Sets the colorscale. The colorscale must be an array containing arrays mapping a normalized value to an rgb, rgba, hex, hsl, hsv, or named color string. At minimum, a mapping for the lowest (0) and highest (1) values are required. For example, `[[0, 'rgb(0,0,255)'], [1, 'rgb(255,0,0)']]`. To control the bounds of the colorscale in color space, use `zmin` and `zmax`. Alternatively, `colorscale` may be a palette name string of the following list: Blackbody,Bluered,Blues,Cividis,Earth,Electric,Greens,Greys,Hot,Jet,Picnic,Portland,Rainbow,RdBu,Reds,Viridis,YlGnBu,YlOrRd.

• contours

• customdata

  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

• customdatasrc

  Sets the source reference on Chart Studio Cloud for `customdata`.

• da

  Sets the x coordinate step. See `x0` for more info.

• db

  Sets the y coordinate step. See `y0` for more info.

• fillcolor

  Sets the fill color if `contours.type` is *constraint*. Defaults to a half-transparent variant of the line color, marker color, or marker line color, whichever is available.

• hovertext

  Same as `text`.

• hovertextsrc

  Sets the source reference on Chart Studio Cloud for `hovertext`.

• ids

  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.

• idssrc

  Sets the source reference on Chart Studio Cloud for `ids`.

• legendgroup

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

• legendgrouptitle

• legendrank

  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.

• line

• pmeta

  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.

• metasrc

  Sets the source reference on Chart Studio Cloud for `meta`.

• name

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

• ncontours

  Sets the maximum number of contour levels. The actual number of contours will be chosen automatically to be less than or equal to the value of `ncontours`. Has an effect only if `autocontour` is *true* or if `contours.size` is missing.

• opacity

  Sets the opacity of the trace.

• reversescale

  Reverses the color mapping if true. If true, `zmin` will correspond to the last color in the array and `zmax` will correspond to the first color.

• showlegend

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

• showscale

  Determines whether or not a colorbar is displayed for this trace.

• stream

• text

  Sets the text elements associated with each z value.

• textsrc

  Sets the source reference on Chart Studio Cloud for `text`.

• transpose

  Transposes the z data.

• uid

  Assign an id to this trace, Use this to provide object constancy between traces during animations and transitions.

• uirevision

  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.

• visible

  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).

• xaxis

  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.

• yaxis

  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.

• z

  Sets the z data.

• zauto

  Determines whether or not the color domain is computed with respect to the input data (here in `z`) or the bounds set in `zmin` and `zmax` Defaults to `false` when `zmin` and `zmax` are set by the user.

• zmax

  Sets the upper bound of the color domain. Value should have the same units as in `z` and if set, `zmin` must be set as well.

• zmid

  Sets the mid-point of the color domain by scaling `zmin` and/or `zmax` to be equidistant to this point. Value should have the same units as in `z`. Has no effect when `zauto` is `false`.

• zmin

  Sets the lower bound of the color domain. Value should have the same units as in `z` and if set, `zmax` must be set as well.

• zsrc

  Sets the source reference on Chart Studio Cloud for `z`.
