Graph Control Flickers After PlotBitmap() Has Been Used.

[Julio Jansson]

 Hi there,

My application requires me to update Plots in a graph control at a defined refresh rate in real time (currently 10 Hz, but to be soon changed to a higher frequency) . In normal operation mode this does not pose a problem, until I call PlotBitmap() in which case, regardless whether the plotted bitmap is on or off the screen, all subsequent plots make the graph control to flicker whilst being update. In which case it only returns back to normal if the applications is restarted. I suspect that some "behind the scenes" attribute gets set once PlotBitmap() is called and unfortunately from there on the final result is almost unusable. I wonder if this is a bug or some attribute that could be reset in order to make it respond normally? I am using CVI 7.0, so would version 8.0 or even 7.1 have a solution for my problem?

Cheers,

Hello,

I tried to reproduce this behavior in the latest version of CVI, but wasn't able to (I'm attaching my attempt below). Can you try running it, and see if it happens for you?

If you can't reproduce it with my test program, would you be able to post a small version of your program that does reproduce it?

Thanks,

Luis
