is it possible to generate a histogram with 2 parameters and plot it as stack columns? For instance: one parameter is time and second parameter is binary (ON or OFF). The histogram should plot columns for each bin. Each column hight should correspond to the number of events in a bin and each column should also give the number of events which were ON and OFF, i.e. X Y1(ON) Y2(OFF) 0-10 2 1 10-20 3 2 20-30 1 3
So basically you want to perform frequency count using a 2nd grouping variable....the current frequency count tool does not support grouping, but you can do this with the 2D Frequency Count/Binning tool under Statistics->Descriptive Statistics menu. In the picture below the On/Off data was set up as 0 and 1 and then bin centers were used in the dialog to set centers to be 0 and 1 for the on/off. Then once you get the output sheet with counts you can make column plots from it.
