multiple plots in one graph (LabVIEW to Excel)

[emerida]

Hi All-

Reference this initial discussion: https://forums.ni.com/t5/LabVIEW/Place-Multiple-Data-Sets-on-One-Graph-LabVIEW-to-Excel/td-p/2164380

Problem description: Generated multiple 2D arrays with different x-axis and y-axis values cannot be placed into ONE excel graph (looking for LabVIEW solution). 

We tried several options.  1) Coercing the data to have the same x-axis works in the sense that I get a graph (of the multiple data sets) but the graph is bogus since the x-values are different enough that the graph isn't correct.  (This was suggested in the referenced post).  The x-values are output power and y-values are efficiency.  2) We can feed the x-values and y-values into a bundle element and wire the output into a waveform graph element which works great but again the output needs to be fed into excel.  (also suggested by the reference post).  3) Lastly, we tried using the Excel Update Graph.vi but unfortunately we were only able to plot the last data set because it looks like the graph gets updated on each loop run and ultimately we only get the last data set.  4) As a final effort we tried looking into the sub.vi but that didn't get us any closer to x-values and y-values plotted in excel with LabVIEW generated data.

Any suggestions?

Thanks!

Hi,

You attempted to invoke nodes? Add a  invoke node of the waveform graph, so this add data to excel. There are several types of  invoke  nodes that can be used, such as  invoke node "Export data to Excel" or the invoke node "Export data to excel Plot".
