Plotting data

[GHernandez]

Hey all,
I am looking for some advice on how to plot resistance data for 4 channels, each with 8 sensors. Ideally, I could plot for each 4 channel, but not sure how cpu intensive is plotting on the PDA.  What is the best method to plot 8 different data points updated every 20 seconds or so??

GHernandez,

If you're only updating the plots every 20 seconds or so you should be able to graph these signals pretty much any way you want.  The only time that you might run into problems would be if you were aquiring data at a fast rate and wanted to plot each point as it comes in real-time.  Plotting data is more cpu intensive than most operations but at the slow rate that you're talking about you shouldn't have any problems at all.

Hope this helps,
