Hi,

I have a file, containing 762 lines and 3 columns.

The columns are x,y,z respectively and I want to plot z on x,y grid which is a surface!

I know that I can use surf but in my case 762 z values cannot be reshaped to a matrix.

If I reshape it to 20*39 then I would lack 18 lines. (20*39)-762=18

Is there a way I can plot it directly?
