Graph component

Description

Graph can be used to render any plotly.js-powered data visualization. You can define callbacks based on user interaction with Graphs such as hovering, clicking or selecting

Usage

dccGraph(id=NULL, responsive=NULL, clickData=NULL,
clickAnnotationData=NULL, hoverData=NULL,
clear_on_unhover=NULL, selectedData=NULL, relayoutData=NULL,
extendData=NULL, restyleData=NULL, figure=NULL, style=NULL,
className=NULL, animate=NULL, animation_options=NULL,
config=NULL, loading_state=NULL)

Arguments

id

Character. The ID of this component, used to identify dash components in callbacks. The ID needs to be unique across all of the components in an app.

responsive

A value equal to: true, false, 'auto'. If True, the Plotly.js plot will be fully responsive to window resize and parent element resize event. This is achieved by overriding 'config.responsive' to True, 'figure.layout.autosize' to True and unsetting 'figure.layout.height' and 'figure.layout.width'. If False, the Plotly.js plot not be responsive to window resize and parent element resize event. This is achieved by overriding 'config.responsive' to False and 'figure.layout.autosize' to False. If 'auto' (default), the Graph will determine if the Plotly.js plot can be made fully responsive (True) or not (False) based on the values in 'config.responsive', 'figure.layout.autosize', 'figure.layout.height', 'figure.layout.width'. This is the legacy behavior of the Graph component.

Needs to be combined with appropriate dimension / styling through the 'style' prop to fully take effect.

clickData

Named list. Data from latest click event. Read-only.

clickAnnotationData

Named list. Data from latest click annotation event. Read-only.

hoverData

Named list. Data from latest hover event. Read-only.

clear_on_unhover

Logical. If True, 'clear_on_unhover' will clear the 'hoverData' property when the user "unhovers" from a point. If False, then the 'hoverData' property will be equal to the data from the last point that was hovered over.

selectedData

Named list. Data from latest select event. Read-only.

relayoutData

Named list. Data from latest relayout event which occurs when the user zooms or pans on the plot or other layout-level edits. Has the form '<attr string>: <value>' describing the changes made. Read-only.

extendData

Unnamed list | named list. Data that should be appended to existing traces. Has the form '[updateData, traceIndices, maxPoints]', where 'updateData' is an object containing the data to extend, 'traceIndices' (optional) is an array of trace indices that should be extended, and 'maxPoints' (optional) is either an integer defining the maximum number of points allowed or an object with key:value pairs matching 'updateData' Reference the Plotly.extendTraces API for full usage: https://plotly.com/javascript/plotlyjs-function-reference/#plotlyextendtraces

restyleData

Unnamed list. Data from latest restyle event which occurs when the user toggles a legend item, changes parcoords selections, or other trace-level edits. Has the form '[edits, indices]', where 'edits' is an object '<attr string>: <value>' describing the changes made, and 'indices' is an array of trace indices that were edited. Read-only.

figure

'config' is set separately by the 'config' property

style

Named list. Generic style overrides on the plot div

className

Character. className of the parent div

animate
