Re: [Matplotlib-users] move legend

S=E6ll !


I was simply planning to be able to move between the default positions 'upp=
er right', 'upper left', etc
But I believe I can use _offset.

However it did not produce much effect

I have defined the legend the following way:
canvas.leg=3DFigure.legend(canvas.figure,tuple([i[1] for i in d]),tuple([i[=
0] for i in d]),'best')


And then when I toggle a button I apply the following move with the canvas =
object, which is just  a test offset

    def toggle_legend(self, event):
      """ Toggle the label in the legend button=20
          between Upper Right and Upper Left """
           =20
      if self.Legend_button.get_active()=3D=3D1:
         self.Legend_button.set_label("Upper Right")
      else:
         self.Legend_button.set_label("Upper Left")

      self.leg._offset(0.1,0.56)
      self.draw()
 =20
    return

When I toggle the button, the label changes, but the legend is unmoved.


Am I missing something ?=20
