I'm analyzing a series of events that have a start time and an end time. I would like to plot an area chart with time on the x axis and on the y axis the number of events that are ongoing at that moment (start < x < end). Is this possible at the moment?
The result would be something similar to de date histograms only we count how many times x lies between two values instead of counting how many times a value lies in an interval.
Help would be greatly appriciated
