delete and add data points to the original file interactively

Hi all,

I’m a python programmer and I was trying to delete and add data points to a file interactively by making plots. For instance, if I have a plot like this:

How could I delete a point from the file by clicking on the figure? And could I mark it as other symbols

if I delete it or select it? After selecting appropriate points, I want to put these information into

a new file.

Thanks a lot for the help.

Would love to know the answer as well. I will be looking at some regression history, and if i see one funky data point, i would like to remove it from the list/database if the user deletes it interactively.

Thanks
