Hello,

I am trying to do a 3d plot of an m x n matrix. I know that each point is plotted as an elevation on the z axe versus its respecctive row (x axis) and column y axis index. The values in the matrix are very diffrent, i mean i have -62 1.2 1 and 5.7 *10^9, and i don't find for example the poin (1,1,-62) on the plot. Is it because the max values are so diffrent from the min values? Thank you

Please post the worksheet. It's all but impossible to give you any advice without seeing the problem.

This is the data that i was talking about. I don't think that point is visible due to the differences between the max and min values.

Very Likely.

Can you manually set the lower limit in Prime? Here's what you get when you turn off Auto Grid in M15. You still can't really make out which values are the smallest, but at least you can see what the minimum value is.
