For me, doing:
sum(Value)/ sum(Total Value)
results in a bar chart ranging from 0 to 1 with each segment broken by dimension 2.
The percentages of this is what I am looking for, but I still want the bars to vary in length as if it was being plotted by sum(Value)
The reason for this is that we want to see the magnitude of differences between dimension 1 while still understanding per bar, the percentage of each segment contributing to that dimension 1.
