making two graps into one

[labview1958]

I have attached a vi. I am trying to have only one graph. Is that possible? When I choose the frames, I automatically also choose which graph. Possible in labVIEW 6.0?

Yes, it is possible, but first we need to find out what you actually want. 😉

• What is this VI supposed to do?
• What is your definition of "when I choose the frames"?
• What data should be on the charts (both, one or the other, etc.)?
• Charts don't make much sense in a VI that only runs once.
• Shouldn't the code be in a while loop for example?

Questions and answers. * What is this VI supposed to do? Measure three things. * What is your definition of "when I choose the frames"? My electronic circuit has a switch, thus I sometimes RUN program A and sometimes program B depending on which circuit is switched on. * What data should be on the charts (both, one or the other, etc.)? One chart should have data (x,y1) and the other (x,y2) * Charts don't make much sense in a VI that only runs once. There is a for loop with n iterations that have been omitted to save space. * Shouldn't the code be in a while loop for example? The code is supposed to be in a for loop. I need to have only one graph but my program is supposed to collect data (x,y1) or (x,y2). I do not want to collect x, y1 and y2 together only either (x,y1) or (x,y2) for any one test.

If you make the data type the same in each case, you can wire the output of all cases to a single output tunnel. Since you have an Acquire Waveform, you can make the data types in the other cases a waveform datatype with the Build Waveform function. Here's a picture of what you could do in the cases that don't normally return that data type.
