[Matplotlib-users] Event attributes

[Martin W. <mp...@bh...>]

Hi,

I'm using matplotlib in a GTK gui canvas with the GTKAgg backend.  I'm 
connecting a mouse click 'button_press_event' to the click function.  If 
I choose print event.x everything works fine.  However I'm after the x 
value in terms of the x-axis not pixels.  When I try print event.xdata I 
get an error message.  Am I making a stupid mistake or is this a bug?

Thanks

Martin

  
    self.canvas.connect('button_press_event',self.click)

def click(self,widget,event):
        print 'you clicked', event.xdata, event.ydata
        #print 'you clicked', event.x, event.y


Traceback (most recent call last):
  File "./dangerplotpy", line 120, in click
    print 'you clicked', event.xdata, event.ydata
AttributeError: xdata
