I have two sets of data each is a time and a value. The range of times for the two sets overlaps but the time points in each set are different. I want to plot the values on a time scale to compare them. So to be clear I have
a timestamp in col. A and a value in col. B a timestamp in col. C and a value in col. D.
I’d like to plot two lines for col.s B and D with the x axis being the time scale in the columns A and C.
Any hints on how this can be done? I effectively want my x-axis to be a merge of of the col. A and C values.
