suggestion for the toolbar

Hi John,

What do you think of adding a button to the standara toolbar allowing the plotted data to be save in CSV format?

It woul be very convenient when the user wants to take the data to another plotting program, and the plot is a good place to save because the data is already sorted out. In some types of plots such as the histogram, the plot woul allow for saving the actual data that represents the histogram (such as class intervals or mid points and frequencies) instead of the raw data.

What do you think?

Talking about plots, I am writing a module to calculate Kernel density estimates (a kind of continuous histogram) would you be interested in adding it to matplotlib?
