This sparked a follow-up question for me, not sure if it should be posted as a separate post or not. Posting it here for now. So Splitting the series on the type of event produce the visualization I need. However I noticed something strange. Looking at the visualization below the cumulative sum drops for certain types of events which doesn't make sense to me.
It's like if the last bucket doesn't have any values it defaults to 0 instead of the previous cumulative sum from the last bucket.
Zooming in on last 24 hours makes this even more apparent (previous image was last 30 days)
Is there anyway to get around this or is it intended behavior?
