Im playing with this amizing tool.
Not doing something special yet.

Now I'm trying to set background image.

I'm want to avoid reploting it. Is the background is reploting when calling replot?

I didn't find in the examples image loading so I used this question as reference


The image is actually loading.
But when I zomming in, in some point the image disappearing.
And when I zoom out, the drawing is takes a while and the windows some time freeze until it load back.

Can some explain the logic behind the image drawing? And how to avoid it.
