I have a collection of timestamped events being part of two categories. I can filter on a field to get the events of any and display them as a histogram aggregated by timestamp. So far so good.
I can't plot both on the same plot though. I only managed to add global filters. I would simply like to see at any given time what proportion of one I get over the other.
How could I do that? I can't seem to find any filter at the metrics level.
