JavaScript Figure Reference: scatter Traces
scatter trace is an object with the key "type" equal to "scatter" (i.e. {"type": "scatter"}) and any of the keys listed below. The scatter trace type encompasses line charts, scatter charts, text charts, and bubble charts. The data visualized as scatter point or lines is set in `x` and `y`. Text (appearing either on the chart or on hover only) is via `text`. Bubble charts are achieved by setting `marker.size` and/or `marker.color` to numerical arrays.
- type
Parent:data[type=scatter]
Type: "scatter" - name
Parent:data[type=scatter]
Type: stringSets the trace name. The trace name appears as the legend item and on hover.
- visible
Parent:data[type=scatter]
Type: enumerated , one of (true|false|"legendonly")
Default:trueDetermines 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=scatter]
Type: boolean
Default:trueDetermines whether or not an item corresponding to this trace is shown in the legend.
- legend
Parent:data[type=scatter]

- legendrank
Parent:data[type=scatter]
Type: number
Default:1000Sets 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.

- texttemplate
Parent:data[type=scatter]
Type: string or array of strings
Default:""Template string used for rendering the information text that appears 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. Variables that can't be found will be replaced with the specifier. For example, a template of "data: %{x}, %{y}" will result in a value of "data: 1, %{y}" if x is 1 and y is missing. Variables with an undefined value will be replaced with the fallback value. All attributes that can be specified per-point (the ones that are `arrayOk: true`) are available.
- texttemplatefallback
Parent:data[type=scatter]
Type: number or categorical coordinate string
Default:-Fallback string that's displayed when a variable referenced in a template is missing. If the boolean value 'false' is passed in, the specifier with the missing variable will be displayed.
- hovertext
Parent:data[type=scatter]
Type: string or array of strings
Default:""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.
- hoverinfo
Parent:data[type=scatter]
Type: flaglist string. Any combination of"x","y","z","text","name"joined with a"+"OR"all"or"none"or"skip".
Examples:"x","y","x+y","x+y+z","all"
Default:"all"Determines what trace information appears 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=scatter]
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. Variables that can't be found will be replaced with the specifier. For example, a template of "data: %{x}, %{y}" will result in a value of "data: 1, %{y}" if x is 1 and y is missing. Variables with an undefined value will be replaced with the fallback value. 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, all 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>`.
- hovertemplatefallback
Parent:data[type=scatter]
Type: number or categorical coordinate string
Default:-Fallback string that's displayed when a variable referenced in a template is missing. If the boolean value 'false' is passed in, the specifier with the missing variable will be displayed.
- xhoverformat
Parent:data[type=scatter]
Type: string
Default:""Sets the hover text formatting rule for `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=scatter]
Type: string
Default:""Sets the hover text formatting rule for `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.

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=scatter]
Type: number or categorical coordinate stringAssigns 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=scatter]
Type: data arrayAssigns 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
- xaxis
Parent:data[type=scatter]
Type: subplotid
Default:xSets 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
Parent:data[type=scatter]
Type: subplotid
Default:ySets 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.
- orientation
Parent:data[type=scatter]
Type: enumerated , one of ("v"|"h")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`.
- groupnorm
Parent:data[type=scatter]
Type: enumerated , one of (""|"fraction"|"percent")
Default:""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.
- alignmentgroup
Parent:data[type=scatter]
Type: string
Default:""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.
- offsetgroup
Parent:data[type=scatter]
Type: string
Default:""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.
- stackgroup
Parent:data[type=scatter]
Type: string
Default:""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.
- xperiod
Parent:data[type=scatter]
Type: number or categorical coordinate string
Default:0Only 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.

Default:"middle"Only relevant when the axis `type` is "date". Sets the alignment of data points on the x axis.
- xperiod0
Parent:data[type=scatter]
Type: number or categorical coordinate stringOnly 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.
- yperiod
Parent:data[type=scatter]
Type: number or categorical coordinate string
Default:0Only 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.
- yperiodalignment
Parent:data[type=scatter]
Type: enumerated , one of ("start"|"middle"|"end")
Default:"middle"Only relevant when the axis `type` is "date". Sets the alignment of data points on the y axis.
- yperiod0
Parent:data[type=scatter]
Type: number or categorical coordinate stringOnly 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.
- marker
Parent:data[type=scatter]
Type: object containing one or more of the keys listed below.- angle
Parent:data[type=scatter].marker
Type: angle
Default:0Sets the marker angle in respect to `angleref`.
- angleref
Parent:data[type=scatter].marker

- autocolorscale
Parent:data[type=scatter].marker
Type: boolean
Default:trueDetermines whether the colorscale is a default palette (`autocolorscale: true`) or the palette determined by `marker.colorscale`. 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
Default:trueDetermines 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: numberSets 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: numberSets 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: numberSets 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=scatter].marker
Type: color or array of colorsSets 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=scatter].marker
Type: subplotidSets 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=scatter].marker
Type: object containing one or more of the keys listed below.- bgcolor
Parent:data[type=scatter].marker.colorbar
Type: color
Default:"rgba(0,0,0,0)"Sets the color of padded area.

Parent:data[type=scatter].marker.colorbar
Type: color
Default:"#444"Sets the axis line color.
- borderwidth
Parent:data[type=scatter].marker.colorbar
Type: number greater than or equal to 0
Default:0Sets the width (in px) or the border enclosing this color bar.
- dtick
Parent:data[type=scatter].marker.colorbar
Type: number or categorical coordinate stringSets 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"
