How to plot two signals i.e x vs y

[tronoh]

Dear sir

I want to plot two signals (one is current and other is voltage). How I can plot current vs voltage. For example,  Attach is the general diagram in which one vi is Simulated Signal and other vi is Simulated Signal 2. So how I plot output of simulated signal vs simulated signal2. 

Kind Regards

You need to bundle each x and y point into a cluster and then build an array of the xy pair clusters. You can then pass this to the XY graph.

OR

Pass your X data and Y data into the "BUILD XY GRAPH" express VI. (this is the EX XY GRAPH in your graph palette).

Dear Sir

 I have try according to your instructions. But it is giving error of different data type. Attach is the block diagram for your reference.

I cannot open the VI as I am using an older version of LabVIEW. If you save it for version 11 I can take a look.

You just made a longer 1D array instead of making a 2D array. Everything you need is clearly explained in the LabVIEW Help file, which is immediately available by right-clicking on the function(s) of interest and selecting Help.

Hi, Tronoh,

I replace your waveform graph with xy graph, and then insert the Convert to Dynamic Data.vi within the dynamic data flow, convert it into 1D double array; then bundle both signals and wire the result to the graph.

Is it what you want?
