2D plot draw command using 2 1D histograms

[ksmith]

I posted an example of two different 2D histograms that produce similar 1D histograms, demonstrating that this is not possible. I thought it might be relevant / educational here.

Rebinning of 2D ROOT histogram in Python

This is still not possible. For example, you cannot know if the low values of x correspond to the low values of y, or the high values (slope positive or negative). Having the two distributions does provide some information about what situations can be excluded, but will not provide a single relation between x and y. Take this example: { TH2D* h2d_A = new TH2D("h2d_A","Dist A", 100, -2, 2, 100, -2, 2); TH2D* h2d_B = new TH2D("h2d_B","Dist B", 100, -2, 2, 100, -2, 2); for (int i=0;i<5…
