Python Matplotlib MouseEvent xy vs. xydata -


i working on project make mouse click interactive pixel map (created pyplot) using python 3.4 , matplotlib 1.4.3. using matplotlib.backend_bases.mouseevent class make figure interactive. i'm getting started, , far have:

# define on_click() function print event data upon mouseclick  def on_click(event):         """print event data on mouseclick"""         print(event)

when click on figure, here's kind of output get:

mpl mouseevent: xy=(289,265) xydata=(24.5956632653,21.9489795918) button=1 dblclick=false inaxes=axes(0.141923,0.1;0.603077x0.8)

can tell me xy part means? it's 50x50 pixel map, xydata pixel position of mouse click.

it position left , bottom of canvas, respectively.

here documentation:

the following attributes

x- x position - pixels left of canvas
y- y position - pixels bottom of canvas

canvas- figurecanvas instance generating event
