Video: Cross-Filtering from a Combo Bar Chart by Selected Column Using Transpose

A Sigma user recently reached out in my support chat for advice on this filtering action. They had a combo bar chart with multiple value columns and wanted to dynamically filter another part of their workbook based on exactly which bar was clicked. The challenge: when several columns share the same Y-axis, an on-select action can’t tell which column was actually selected since they all refer to the same row.
