What is the problem or goal the end user is trying to solve or accomplish?
With cross-filter enabled, when the user clicks on a value, it will apply a cross-filter against that value to other charts. For Bubble and Histogram charts, cross-filter can be applied to the chart, but it is not possible to set a cross-filter value from the chart itself.
How are they solving it currently?
It is not possible at the moment.
What is the recommended solution by the Customer?
Enable applying cross-filter FROM Bubble and Histogram Chart.
