Hello @July
Are you still working on this or were you able to find a solution?
I think that @prantika_sinha 's example above is the closest solution but I’m not sure I totally understand the end objective. To clarify, you want a stacked bar chart with 6 segments sorted from highest to lowest, with the first 5 being actually category names and the 6th saying “Other” by month.
If the above is the case, ultimately, I don’t think there is a way to control the order of the segments in the bars via sort orders in the field well. It seems to be based on alphabetical/numeric order of the field value i.e. A, B, C, D or 1, 2, 3 etc… This topic still has what I think is the best solution:
