Advice needed for presenting multiple tables in an organized way

A multi page layout (Igor 7 or later) with a table on each page might do what you're looking for. You could add additional text to each page using either an annotation or drawing text. Or you could just put all three tables on the same page with text.

As for #3, there's no practical way to do this in Igor. One approach would be to create a control panel with a list box. The list box requires a text wave, but it does allow you to use styled text and can display the styled text. Here's an example (tested with Igor 8) that gives you an idea of what I'm thinking.

For a simple presentation, an option is to use a formatted notebook, possibly as a subwindow in a control panel.

To get started, create a standalone formatted notebook manually and enter and format sample text as you wish manually. Then choose Notebook->Generate Commands, then paste into procedure window to see the commands needed to recreate that notebook.

Actually for operation #3, my supervisor gave a good solution by using just the color map, and I code it into the below:

I will explore the other two features suggested above, thanks a lot for the ideas!
