Finding peak with cgHistoplot and bin confusion [message #87111]

I'm using cgHistoplot with the binsize value set like so:

cgHistoplot, data, binsize=100, xrange=[0, 8000]

Is there a simple way to find the x value where the histogram peaks?

I thought using the histdata keyword would have worked and then something like find=where(histdata EQ max(histdata)).

The problem though is then knowing which bin that subscript refers to. I assumed because I specify xrange starting from 0 then my first bin would be 0-99. However, if I use the omin keyword it returns a value of 698.045. Does that mean by first bin is 600-699? or 698.045-797.045?

Cheers
