[Matplotlib-users] efficient redrawing?

[Jeff P. <jef...@se...>]

Hello, I'm not sure I have the most efficient method for changing my
plot settings.  I have an application I wrote with maplotlib that allows
a user to plot data and change different plot settings like color and
line width etc.  Initially when the program is created I create a
default axes with no data plotted.  The user then loads the data and
presses a plot button.

Once the data is plotted, each time the user changes the settings (for
example they change the line color from red to blue) I call
axes.clear(), then I call plot() again and this time I use the keywords
to change the settings to (change the line color to blue) and then I
call canvas.draw() to redraw the canvas.

axes.clear()
axes.plot(array,color=color, linestyle=pattern, linewidth=width,
marker='None')
canvas.draw()

Is this the best way to do this?

Thanks.

Jeff
