Suppress default hover_data

[alecfwilson]

Is there any way to suppress the default hover_data when the hover_data argument is passed? For example, my plot doesn't need the x, y, and color args in the hover_data, but I can't figure out how to remove them.

At the moment there's no way to do this from the arguments, but this is something I'll look into. You can modify the hoverlabel contents fairly easily by modifying the hovertemplate attribute of the traces.

Right now the default value of hover_data is None, and it accepts an array of columns to add to the existing set of key-value pairs listed (which currently include every value mapped to some visual attribute in the chart). In terms of API, I could imagine either adding a new kwarg hover_data_exclusion or having hover_data accept a dict which would control if/how values are displayed. Someone recently suggested the idea of this kind of API to control the precision/formatting of numbers in hover labels with e.g. hover_data={"column": "format"} and this would fit in pretty nicely as hover_data={"column": False}

Will be completed in plotly/plotly.py#1774

For px.choropleth_mapbox, there is no hovertemplate parameter, right? I hope to do custom formatting like in go.Choroplethmapbox.

And I found that px.choropleth_mapbox has a template parameter, but I can't find any doc about it. Is there something I missed? Thanks.

I have the same issue with px.scatter_mapbox as well. Currently, lat, lon and color are also being included in the hover text and there is no corresponding hovertemplate.
