Origin Ver. and Service Release (Select Help-->About Origin): v8 SR0
Operating System: windows XP

the txt data are composed of three columns, which are x, y, z, respectively.It is acturally 640x480 pixels. Thus x values changes from 0 to 639 while y is fixed at 0, and again x changes from 0 to 639 while y is fixed at 1, and so on and so forth. So how to use the three columns to plot a 3D figure, or how to convert the data into a 640x480 matrix?
Thanks a lot.

Hi,

You can convert the data into matrix by using XYZ gridding first. And then plot 3D figure with the result matrix.

By the way, you can update to Origin 8 SR6 from this page.
