I want to make a graph where I plot an x variable against a Y, but also have a z-axis or ideally
a contour plot, where this extra axis is number of entries.
Or to put it another way I have the Y axis vaiable as a histogram and want to plot this histogram
for different values of the x-axis to make a kind of a either 2d TGraph or 1D cotour TGraph (ideally).
Does anyone have any suggestions to the right way to do this, as my plots are not working.
