I am a new rooter.
I got a 2D histogram with the fixed bin size in x and y axis. But I want to set a condition on the entries of each bin, e.g. if bin #1 contains entries more than some value, then divide this bin to satisfy this condition, if bin #2 contains entries less than some value, then merge the adjacent bin to achieve that.
In one word, how can I choose the binning adaptively to allow the equal number of entries in each bin in a 2D histogram?
Thanks in advance
