Python Visualization: Determining Data Attributes Visually by Mouse Hover and Click

I am rendering very large X,Y,Z scientific datasets in the lateral plane and would like to click on the results to obtain greater textual detail about the area chosen by mouse-click.

So, for example, imagin开发者_Python百科e a scientific dataset which is rendered as a filled contour plot and there is a bright spot. I would like to click on that spot to obtain a link or other textual information.

This would necessitate having another plane that would provide attribute information.

I would be most appreciative for any direction that others have used in similar cases. I expect this problem has been solved previously so I would prefer not reinventing the wheel.

Sounds like you'll need to dive into matplotlib's event handling code. This allows you to take some action when you click on a piece of the plot, or press a key, or whatever. Here are the example programs on the matplotlib site that have to do with event handling.
