Histogram hovertext

Dash Python
1

Hi there,

I am hoping someone can give me some help on this one - with hovertemplate, how do I reference the start/end of a bin, and the y value (when the y value is not an input).

                go.Histogram(
                    x=values,
                    name=group,
                    xbins=dict(
                        start=0,
                        end=maximum,
                        size=binsize,
                    ),
                    histnorm='percent',
                    bingroup=1,
                    opacity=0.2,
                    cumulative=dict(enabled=True,
                                    direction='decreasing'),
                ),

so on hover I want it to say “25-50, 15%”, which is equivalent of something like “{x_start}-{x_end}, {y:.0%}”

My problem is I don’t understand how to get x_start and x_end, and y doesn’t exist!

Many thanks
