Time Scale Graph questions

[heepofajeep]

    Hi, I am VERY new to Labview.  I am using Labview 7.0  with a PCI 6220 card.  I have a VERY simple VI that plots input voltage [+/- 10V] with respect to time. Currently the graph plots continuosly each time a measurement is taken [Tmax - Tmin = ~1ms].  I want to graph to instead plot a continuous graph with a curve that starts at Tmin = 0, and ends at Tmax=1min, giving me a complete curve.

Your help would be very much appreciated!!!

Hi heepofajeep,
    Here's a screenshot I hope will help you.  Basically, if you append the waveform each time through the loop, you can display it all on the graph at the same time.

Thank you, the picture is very helpful.  My only question is, how do I insert the constant 'block' that is outside the While loop with the pink outline?  Thanks!

You can't with 7.0. It's a waveform constant but in 7.0, you can only have a waveform control on the front panel. Just go to the front panel and select it from the I/O palette.

The other way to graph continuously is to right click on your graph and replace the graph with a chart. You don't have to use the build array then. You do have to set the chart history length to be large enough though.
