Pass Legend clicked value to a drilldown report
I have a pie chart.Now I want to show another pie report when clicked on a legend of first pie chart. For this, in the Interactivity window, I selected drill-down on mouse click and selected a different report. But the challenge I am facing here is that how can I pass the clicked legend value to my drilldown report as a parameter. Any help or suggestion would be greatly helpful.
I read one of the post that using the Optional datapoints URL parameters we can achieve, but for some reason my category series is disabled in drilldown edit window.
