How to autoscale matplotlib X&Y axis after set_data() call
After calling set_data() or set_ydata() in matplotlib the axis scale is not updated automatically. Use
ax.relim()
ax.autoscale_view(True,True,True)
to update both the X and the Y scale.
Full example:
line.set_data(x, y)
# Autoscale view
ax.relim()
ax.autoscale_view(True,True,True)
# Redraw
figure.canvas.draw()
figure.canvas.flush_events()
