I am working to develop a program to demonstrate physiologic effects using a spring model. Part of the output will be 3 - 5 waveforms as if looking at an oscilloscope. I was considering the use of particles or changing pixels on a bmap. I do not wish to reinvent the wheel. Does anyone have a solution or the ability to direct me to a solution. My students, residents, fellows and I will be very grateful. Thank you in advance.

I would do this with the "draw_line" (http://www.conitec.net/beta/draw_line.htm) instructions in combination with some simple math function to create the coordinates.

Here I made small example:

Works well. Thank you very much. Will build your routine in my project. I might return if success eludes me.
