Hover template for chart with "base"

Hello!

I am creating a figure which is a Waterfall chart.

In this Waterfall chart, I am using the ‘base’ parameter.

This works perfectly for me, but I noticed a problem with the hovertemplate…
As soon as I have data below my ‘base’, the hover doesn’t work well… It doesn’t work when I am on the bar, I will let you see this in the video.

Here is the code:

import plotly.graph_objects as go

x_values = ['Waiting on union or regulatory problem', 'Up log wireline to depth inside drillstring',
                'Drill to depth', 'Slickline run other activities', 'Service Well Control Equipment',
                'Trip in to depth', 'Trip out to depth', 'Run in casing to depth', 'Drilling run other activities',
                'Rig up to run slickline', 'Run in slickline to depth', 'Make up BHA', 'Circulate to condition hole',
                'Waiting on cement to develop strength', 'Circulate to condition drilling fluid',
                'Smallest differences combined']
y_values = [-4.83333333, 1.14583333, 1.125, 1.08333333, 0.75, 0.5625, 0.5, -0.45833333, 0.41666667, 0.375, 0.35416667, -0.33333333, 0.33333333, -0.33333333, 0.29166667, 0.875]

fig = go.Figure(
        go.Waterfall(
            orientation="v",
            base=17.5625,
            x=x_values,
            y=y_values,
            customdata=y_values,
            hovertemplate=(
                    "%{x}<br>" + "Initial: %{initial:.2f}<br>" + "Final: %{final:.2f}<br>" + "Delta: %{delta:.2f}<extra></extra>"
            ),
        ),
        layout={"height": 800}    

    )
fig.show()

Thanks!

base、y_values、および initial、final、delta を含む hovertemplate を使用する、提供された go.Waterfall の例から始めます。base より小さい値でホバーの動作を再現し、その後、各バーにホバーしたときに期待される template の値が表示され、チャート全体で一貫して動作することを確認します。
