Reverse Axis for TGraph and Fit

@couet TGraphPainter has a baked in option for reversing x and y axes. I’m struggling to get TObjects (like my fit, or various lines/boxes) to match the reversed axes.

TGraphErrors *g = new TGraphErrors(n,x,y,ex,ey);
g->Draw("ALP RX");

the above code will produce the TGraph reversed, but the fit with the original axes.

Dear all,
what should I do to flip the y-axis in the case of a TGraph2D, please?
I have tried:

TGraph2D gr("potential.txt");
gr.Draw("colz RY");

But the y axis is not flipped

I am using ROOT 6.18/04

Many thanks in advance and kind regards,

This is not possible for TGraph2D
