I also may be wrong.
I thought ax.plot(..) would redraw everything (ticks, labels, etc) to
do with the plot.
I've been using set_data as I thought it was meant to be quicker.
self.cline[0].set_data(rX, myabs) # I have to make sure
I use correct line
:: ::
self.canvas.draw()
To just change the data associated with a specific line on plot.
I stored the lines on my graph in a list called cline, I captured the
line at time of creating of the plot
r = self.axis.plot( rX, myabs ,self.linestyle, color='b')
self.cline.append( r[0] )
