I appreciate both of your prompt answers. I am going to continue to work with this for awhile but after playing with the examples for a bit I'm still afraid I'm having trouble. I think i don't properly understand the way the data from my DAQ is being output and the way the analog graph is being updated.
You are completely correct that tossing the output of the DAQ into an array as its being plotted so that 100 points later it can be replotted with the new data is what I am trying to do. I just don't think I understand the fine points of array management. Like how do you make sure the 50th, 150th, and 250th etc. measurments (correspondingto 50 AMU on the x axis) are all falling into the 50th position on the array, and then how do you make sure that the graph looks for that data in the 50th position? I'll keep playing with it but thank you both I believe you have saved me quite a few hours of beating my head against the desk. -Paul
