Hi all,

I have built a small event handler to zoom in on a graph on pyplot figure, and then I use the builtin pickline event handler to select a line. I plot multiple lines from a large dataset of ordered series, so when I choose one, I need my program to recognize which column of the original data array this is coming from. Because I'm zoomed in, when I perform the following metaoperation

thisline = event.artist
xdata, ydata = thisline.get_data()

The xdata and ydata are now subsets of the full curve, because I've zoomed in, the full data set is not being shown in the figure. What I'd like to do is
have thisline.get_data() return some sort of identifier so I know immediately which column of the full data matrix I am in.

If there is no built-in way to do it, I need to think of a clever way to take a subset of the ydata for example:

ydata=[100.4, 104.2, 503.4, 980.0]

And figure out to which column this belongs in my original array. I don't want to reinvent the wheel on this, as it seems that a very pythonic solution is lurking somewhere.
