Hi everybody, I want to modify a matplotlib.lines.Line2D and update the plot. I have used Line2D._y member to modify the line. It works. But by doing canvas.draw() (see example below), the line is not updated on the plot. To update it, I have to do autoscale_view(). But I do not want the x and y ranges of the plot to be changed.
How to do this? Thanks in advance, Julien ################### from pylab import * import matplotlib ion() f = figure() s = f.add_subplot("111") X1 = arange( 0.0, 5.0, 0.1 ) # print X1, X1**2 line = matplotlib.lines.Line2D( X1, X1**2 ) s.add_line( line ) draw() raw_input("\npress a key to transform y in y+10") line._y += 10 raw_input("\npress a key to do canvas.draw()") s.figure.canvas.draw() draw() print "The line y has not been updated in y+10" raw_input("\npress a key to do relim, autoscale and canvas.draw()") s.relim() s.autoscale_view() s.figure.canvas.draw() draw() print "The line y has been updated in y+10" print "But the subplot x and y range has changed" print "I want the line to be updated without changing x and y ranges" raw_input("\npress a key to quit") ################# -- python -c "print ''.join([chr(154 - ord(c)) for c in '*9(9&(18%.\ 9&1+,\'Z4(55l4('])" "When a distinguished but elderly scientist states that something is possible, he is almost certainly right.
