Hi Sebastiaan,
If you use a custom hovertemplate then it's possible using d3 format.
More info:
https://plotly.com/javascript/reference/#scatter-hovertemplate
and
https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#d3_format
hovertemplate should be used inside the data-object, so put the json in the advanced tab of the series item.
f.e.:
{
"hovertemplate": "<b>%{x|%d %b}</b><br>%{fullData.name}: %{y} <extra></extra>"
}
GL!
Hey Sebastiaan,
Not sure if you found a solution but maybe have a look at the ‘Tooltip form’ option under ‘Events’ for the chart widget (at least for Pie charts)
Here you can just add a custom page and show any values you want on hover.
Let me know if that solves it?
