Changing the scale for graph?

ROOT
2

I have a PyROOT function which accomplishes the X-axis rescaling, you could re-write it in C++ (basically add curly braces and types).

def rescaleaxis(g,scale=50e-12/1e-9):
    """This function rescales the x-axis on a TGraph."""
    N = g.GetN()
    x = g.GetX()
    for i in range(N):
        x[i] *= scale
    g.GetHistogram().Delete()
    g.SetHistogram(0)
    return

Here are some references on how I obtained that code:

For the Y-axis, I think you can do the same thing but with GetY(). I tried doing another trick by converting to a TH1, TH1::Scale, then converting back to TGraph, but it didn’t work for some reason. I’ll admit I didn’t try very hard to make this trick work.
