I have a set of data that comes in group of 3, "high", "Low", and "end". I want to treat them as a unit. However, when I display my chart, there is no spacing 
In the above image, you can see that I want to have some spacing between "6A" (3 bars) and "6B" (also 3 bars). I tried the following code but it does not work for me. The bargap squeezes the entire chart together (no spacing) and bargroupgap separates each bar individually.
fig.update_layout(barmode='group', bargap=0.1,bargroupgap=0.0)
