A variation of this would be to be able to plot multiple signals on the same chart. For instance, here I would like to compare multiple signals to see which one if the more prevalent: QUICK_ACTIONS_RECROP or QUICK_ACTIONS_DELETE? Unfortunately, the time series shows the total. Maybe if we can say group by signal type this would be a variation of the previous one.
