I managed to build Bora's Sunburst chart but I want to add a few additional filters to it. In his sales example, I added a 'country' filter and the chart works fine with single value filter selected. However, I want the chart to show correctly when 'All' /multiple values in the filter are selected. Right now it seems to show a sunburst chart for each individual value on top of each other instead of combining them.
How can I modify the calculation so that it shows the chart correctly?
