Graph Application Help

[marshg]

I have a real time controller is running at 4kHz, which means that every 250uSec (1/4kHz) the real time controller will be storing a data point from position (and force, output, etc.).  The block size that is defined is 512, which means I will be reading 512 data points every 128mSec (250uSec * 512 = 128mSec).  I want to display this data on the graph; however, I do not need to do this in real time.  I can buffer this data and update the graph every 1 second if I need to.  The only thing that is important is that the data waveform display correctly with a time stamp, which I can easily calculate.  What type of chart should I use (i.e. ChartY, ChartXY, ChartXvsY, or something else)?

Thanks in advance the help!!

If you can generate the time stamp then it really depends on which function you think would do what you want the best.  It's really a matter of what your goal is.  You can read about each of the different methods in the documentation.

Copy and paste this link (ms-help://MS.VSCC.2003/NI.MeasurementStudio/NIVCUI/Objects/CNiGraph/Main.htm) into your browser and you'll be able to search the CNiGraph class for all the Charting functions. 

You will probably need one that takes in a vector as opposed to a single point.  Since you are reading 512 points off the buffer.  You are on the right track with the charting though.  Plotting will override your data.
