Mapbox access token (required to plot mapbox trace types) If using an Mapbox Atlas server, set this option to '' so that plotly.js won't attempt to authenticate to the public Mapbox server.

Define fully custom mode bar buttons as nested array, where the outer arrays represents button groups, and the inner arrays have buttons config objects or names of default buttons See ./components/modebar/buttons.js for more info.

Add mode bar button using config objects See ./components/modebar/buttons.js for list of arguments. To enable predefined modebar buttons e.g. shape drawing, hover and spikelines, simply provide their string name(s). This could include: *v1hovermode*, *hoverclosest*, *hovercompare*, *togglehover*, *togglespikelines*, *drawline*, *drawopenpath*, *drawclosedpath*, *drawcircle*, *drawrect* and *eraseshape*. Please note that these predefined buttons will only be shown if they are compatible with all trace types used in a graph.

Remove mode bar buttons by name. See ./components/modebar/buttons.js for the list of names.

Set on-graph logging (notifier) level This should ONLY be set via Plotly.setPlotConfig Available levels: 0: no on-graph logs 1: warnings and errors, but not informational messages 2: verbose logs

Set the pixel ratio during WebGL image export. This config option was formerly named `plot3dPixelRatio` which is now deprecated.

When set it determines base URL for the 'Edit in Chart Studio' `showEditInChartStudio`/`showSendToCloud` mode bar button and the showLink/sendData on-graph link. To enable sending your data to Chart Studio Cloud, you need to set both `plotlyServerURL` to 'https://chart-studio.plotly.com' and also set `showSendToCloud` to true.

Determines whether to change the layout size when window is resized. In v3, this option will be removed and will always be true.

Determines whether mouse wheel or two-finger scroll zooms is enable. Turned on by default for gl3d, geo and mapbox subplots (as these subplot types do not have zoombox via pan), but turned off by default for cartesian subplots. Set `scrollZoom` to *false* to disable scrolling for all subplots.
