place 6 traces on one graphic

 

i need to place 6 different RF traces on one graphic. This is a P1 db test system that tests gain compression at three frequencies and I need to record gain and output power versus input power for all three freq, six traces in all. 

 

I would idealy like to scale the left side y axis for gain and the right side y axis for output power. 

 

so is it possible to scale the y axis of a graphic in two different ways and then place six arrays of data on the graphic. three scaled to the left side y axis and three scaled to the right side?

 

thanks

Hi Sloppy,

 

I have a couple of questions for clarification that will help us all be able to help you more quickly. Are you wanting to generate this plot to place into a TestStand Report? Or is this plot to be displayed at run-time by LabVIEW (or through another code adapter)?

 

Thanks!

Thanks for the reply

 

I'm using LV 6.1 and I'm not familiar with TestStand.  

 

I was just trying to find a way to display these traces on a single waveform or X-Y plot, whichever is suitable. the problem is three of them are for amplifier gain compression, with gain of around 45-55 dB and the other three traces are for output power of the amplifier ranging from 30-60 dBm

 

So I would like to scale one side of the y-axis for power (30-60) and the other for gain (45-55), as i do now in an older compiler (which I'm trying to get this code out of and into LV).

 

So for the moment I would just like to be able to display it, but eventually be able to save it for later re-call and display, as well as move it into a spread sheet perhaps or produce a hard copy perhaps. 

 

dunno if this helps or not. I hope I'm posting in the correct forum as well

thanks.

Since you posted to the TestStand board, you obviously posted to the wrong one if you are not familar with TestStand.Smiley Wink

 

Right click on your existing scale and select 'Duplicate Scale'. You can then click on a scale and select 'Swap Sides'. You would then click on the plot legend for each plot and go to the Y scale to assign the appropriate scale to each plot.
