Event Connections and subplots in matplotlib

Question

I have what seems to be a simple task yet I am not sure how and where to start. What I currently have is a series of subplots displayed on one figure. Now I want to add/connect an event handler on each subplot, such that when the user clicks on one of the subplots the plot that was selected would be opened in a separate figure/window.
I want to know if this is possible and if someone could formulate a small simple code to illustrate how this can be done. I should also mention that the only type of plot that I am using and interested in are colormaps (using imshow()).

You should read this tutorial.

Basically you need to define function which takes one arguement event and then attach it to your figure's canvas:

def open_new_figure(event):
    if event.inaxes is not None:
        ax = event.inaxes
        # you now have the axes object for that the user clicked on
        # you can use ax.children() to figure out which img artist is in this
        # axes and extract the data from it

cid = fig.canvas.mpl_connect('button_press_event', open_new_figure)
