charting behavior

[densmore]

I have the guts of my DAQ programing working. Just a few questions. Right now I'm using a real simple scatterplot but it doesnt update as often as I would like. It should update the plot in groups of ~100 points or so. but instead in updates the plot in groups of 1000. I need the display to be smooth, otherwise the bossman is going to want to output the display values to the DACs so he can see them on a CRT. Could this be do to the ASync behavior of EndRead???

Right now I'm using a 6024e DAQCard om a 800Mhz laptop. And this simple program is using 99% of the processor and 33MB of memory to run. We are planning on buying a 16bit pci card. Will the DMA on the pci card effect the performance?

Last question for now. If I rewrite the code in a
more OOP manner, how will that affect the performance? Thanks for all your help.

I noticed that you mentioned in another post that you found a solution for the charting issue. Just out of curiosity, what did you find that made the difference? Thanks.

I didn't fix the problem. I need to take more data points than 1012. But when I do, the plot doesn't update.

Sorry - in your other post I read "... and I've been able to get a waveform to plot smoothly" and I thought that you resolved the original problem and that the issue with plotting more than 1012 points was a new problem.
