Multigraph with a linear & a log axis (data set)

I worked it out by using the transparent pad method:

How to plot with a linear and log scale on two different axes on same plot?

I am trying to figure out how to plot something on a linear axis and then plot another quantity on a log axis on the same plot and then have the two y-axes be on different scales as well. I’m currently attempting to do this with drawing the first histogram on a TPad and then drawing the second histogram on a transparent TPad above it. However, I am not sure how to get a log scale for the second histogram (the log scale is a property of the TCanvas I think, not a TPad) and then how to use TGaxis …

However, there are 2 X-axes that are created since the 1st dataset is in X-range of [0,50] and 2nd dataset is in [20,30]. How to plot the 2nd dataset on the X-axis of the 1st dataset?
