Hi,
I have some problems to combine a matshow object with a canvas. Here is a little piece of code that illustrates my problem. It displays a matshow object when pressing a button.
I would like to embed the matshow object into a canvas of a fixed dimension. The code I wrote does the opposite i.e. it is the canvas that adapts its size and not the matshow object. Would you have any hints ?
···
from Tkinter import *
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
import pylab
def display():
mat = pylab.zeros((100,100))
pylab.ioff()
image = pylab.matshow(mat)
pylab.ion()
can = FigureCanvasTkAgg(image, master=frame)
can.show()
can.get_tk_widget().grid(row = 0,column = 0)
root = Tk()
frame =
Frame(root)
frame.grid(row = 0,column = 0)
canvas = Canvas(frame, width = 240, height = 240, relief = “sunken”, bg = “white”)
canvas.grid()
button = Button(root,text=“DisplayMatrix”,command = display)
button.grid(row = 1,column = 0)
Thank you very much
Eric

I suspect this problem will be solved by a change I made to svn last night, providing a matshow Axes method that you would use in place of pylab.matshow. Axes.matshow() simply makes and returns the image; it does not make a figure or set its dimensions, so you have full control over that.
