Changing xlim & ylim of axes sluggish
3 views (last 30 days)
I implemented my own pan & zoom functionality which adjusts the xlim & ylim of an axes as the user moves the mouse. Although this works OK, it's a bit sluggish & "laggy". I'm guessing that the data coming from the mouse is overwhelming the systems ability to change the axes properties.
Does this sound reasonable? If so, does the axes have a "busy updating" flag I can test? Or is there some other explanation?

You have too many processes trying to run at the same time. Even when it sounds incoherent, insert a very short pause right after reading the mouse position
That will refresh the buffer ( or something like that ) and the graphics will be plotted less "laggy".

Not sure if this is exactly the effect you're going for, but for panning around an image via mouse movement, I've found this function: zoom2cursor to be very well-done, and I've used that code as a template to pan around some very large images without any noticeable latency.
