How too find out which bin was clicked in a TH2D histogram

Hi, You can take a look at these tutorials: graphics/triangles.C, hist/exec2.C, hist/DynamicSlice.C and graphics/mandelbrot.C Cheers, Bertrand.

Mandelbrot macro

Dear all, while preparing a small ROOT course, I have written the following macro, that draws the fractal Mandelbrot set, and allows for zoom/unzoom operations. Runs with root mandelbrot.C+ I attach the macro and a screenhsot, just in case someone is interested (maybe a new ROOT tutorial on TExec/TComplex ? [8)] ) Bye Luigi [image] mandelbrot.C (3.24 KB)
