As the attached figure shows, the minimum box is too small to see, how can I adjust the the relative size of the box when using the drawing option “BOX”, I mean making the overall size double or triple times larger for every one.
Change the bin width or set Logz() both work for adjust the size. Well is there any way to draw z axis to show box size representing values if using Logz() way?
No, it is not provided because the scale is always the same: the bins with maximum content are drawn with a box equal to the surface of the bin and the smaller values generate box proportional (in surface) to the bin content. May be you should use COLZ instead
