python - Change range withouth scaling in matplot -


i have question, making program displays zoomed area of peru axis shown in range of image (e.g. 7000x7500) want in utm range (e.g. x-axis between 500000-600000 , y-axis 9500000-9700000) have tried using plt.set_xlim , plt.sety_lim no success, think have use plt.autoscale(false) didn't work or used wrong.

i create figure , axes out of main program

f = plt.figure(figsize=(5,5)) axe = f.add_axes([0, 0, 1, 1])

this function call everytime want plot

def plotear(self, mapa):      axe.clear()     axe.imshow(mapa, cmap='gray', interpolation='nearest')     axe.set_xlim(0,10000) #this testing     axe.set_ylim(0,10000) #this testing     plt.autoscale(false)     self.canvas.draw()

from imshow documentation you'd find there argument extent can used scale image.

extent : scalars (left, right, bottom, top), optional, default: none
location, in data-coordinates, of lower-left , upper-right corners. if none, image positioned such pixel centers fall on zero-based (row, column) indices.

in case you'd use 

ax.imshow(mapa, extent=[5e5, 6e5, 9.5e6, 9.7e6])
