Once I tried developing a component to do just this in VFP. What I found was there is a small memory leak when drawing dots or lines to create the SIN wave. The longer it ran, the more memory it consumed. I reported this to the VFP team, and I guess they felt it was not important enough, at the time, to merit the time to fix. The last time I ran my sample, using VFP 8.0, the leak was still there. So be careful.

>I develop an application for medical needs. User wants the results to display as a chart dynamicly during measurments. Is it possible to do that in VFP? I never play with MS Chart or similar controls.
