graph??

[Viller]

argh!! I'm a little frustrated... here is my problem: Im measuring voltages using a cDAQ and in order to get the filter to work Im using "N (3) samples with 1000 hz" - What I want is to be able to display this input on a graph!! but I cant get it to display a "continous graph"?? instead it shows the 3 samples and then its like it just overrides these samples with the new ones?? instead of creating a "smooth" graph! I have tried using a chart waveform and playing around with the different display mode, but no luck?

can you attach the vi that you are using? Also let us know what version of LabVIEW you are using.

Its not really possible for me to attach the VI, but Im using 8.2........ on my graph the 3 samples are displayed as connected dots, but they are not connected to the next 3 samples. So for each iteration of my while loop 3 samples are displayed as connected dots! hope this makes sense!?

A graph has no history unless you create one. A graph expects an array as an input and if with each iteration, you pass a new array, the old data is lost. A chart is what should be used to display your data. You say you've tried a chart but don't give any explanation of what doesn't work. You will have to provide your VI, an image of the block diagram, or lot more details.
