XY Graph Multiplot Help

No problem, it'd be fine to have them in there then.

Cheers!

Hi,

We are working with the HP4195A network analyzer and are trying to display the readout information using a multiple x-y graph. We would like to display redaout from registers A and B (Y domain) in correlation with the readout from register X that contains frequency information (X domain). We succeeded in displaying A i B while the X domain was defined by sample number (from 0 to 400). We are not sure how to use the graph to show A i B in correlation with frequency that we are reading from the X register. Please see the 'NWAnalyzer Read Trace.vi' in the attachment.

Thank you.

Hi Petra and Daria,

From my understanding it sounds like you want to be able two display two plots (A and B; Y values) correlated to a X axis (frequency values). I looked at your attached .vi. It looks like you need to send your XY graph x values. Right now you are only sending your chart Y values for 2 plots and by default the chart is using 0,1,2...400 (sample number) for the X axis. 

XY Graph.vi in the example finder should be of much assistance; this is for a graph but you should be able to convert these ideas to a chart (the difference between programing for charts and graphs is explained in this Knowledge Base). You need to Bundle your X values with both sets of your Y values, and cluster these together. I have downgraded the XY Graph.vi to LV 8.2 and attached it. Hope this helps.
