Importing and 3D graphing x,y,z data from a csv

Hello everyone,

I'm very new to Igor and am really struggling with my first task. Please forgive a probably very stupid question:

I need to import a csv file that contains 3 variables, x,y,z and about 16,000 lines of data. Once imported, I would like to create a 3D plot, i.e. with an x, y and z axis. Please could someone tell me how I do this? I've been starting with Data>Load Waves>Load Delimited Text, then trying to graph it through Windows>New>3D Plots, but nothing lights up (it is all grayed out, except other), so I'm guessing I'm doing something wrong.

If someone could help me out, I would be extremely grateful.

Many thanks

Jon
If you choose Windows->New->3D Plots->3D Help, the Visualization help file is displayed. It says:

Single column waves can not be used for 2D or 3D plots (e.g., surface plots). If you have 1D waves that you want to plot as 2D or 3D, please read this section carefully.


Read that section for details.

If you don't see the Windows->New->3D Plots->3D Help then you should update to the latest version of Igor.

I've just followed the video tutorial and create my first 3D plot! Thank you very much for your help. I'm very grateful.

Thanks again, Jon
