Colleagues,

Could you recommend a 2D chart control for my application that can work with VB6? I need to plot an EEG signal on the screen in real time. The update rate of the chart will be on the order of 200ms to 1000ms, and I want to display 1000 points. Ideally, the whole chart would scroll to the left as new values are added on the right.

I’ve tried the MSChart, it would work ok, but I don’t know how to get rid of flickering. Flickering is a real problem, because somebody will be staring at the chart for hours.

Thanks and have a happy new year!

Try DynaPlot ActiveX Control

I've use it last year in my PIC-based Logic Analyzer

Have a nice day.:D

I saw it in my search, but I didn't pick it, becasue the trial version is time-limited, and I couldn't figure out how much is a fee for the commercial version.

I ended up choosing the freeware RMCart (http://www.rmchart.com). It's not geared specifically towards the engineering or real-time application, but I found some rokarounds that allow it to work for my signals (which are relatively slow most of the time, although they are sampled at a relatively high rate). If you're curious, I have a thread on the RMChart forum, where I've posted some perfoprmance data: http://www.rmchart.com/webpages/forum/forum_posts.asp?TID=400
