I have a grouped stacked bar chart, as illustrated here: Grouped + Stacked Bar chart
Traces are on the same xaxis, and same yaxis
Each group (A, B C) has 4 stacked bars.
First, how can I get rid of the mention “group1” at the top of the x unified hover?
I found a lot of discussion about this, listed in a post here : Customizing text on x unified hovering - #19 by etonblue
Second, is there a way to get the spike line displayed on a specific group of stacked bar? Currently, there is one single dashed vertical line, above the group in the middle.
Third, it would be better to use a box plot for this, but is there a way to color the different segment of a box plot ?
