How to export entire chart history?

[msiwk]

I was reading the help ( http://zone.ni.com/reference/en-XX/help/371361L-01/lvconcepts/customizing_graphs_and_charts/#Exporti... ) 

on waveform charts and I came across this little bit: "For graphs and charts, you can export only data that is visible in the front panel window".

So I guess that means I can only right click->export the data that is visible on the chart. Is there any way to right click-> export all the data in the chart history? I would like to export all the data from the chart history without stopping the program.

There is a property node for the chart called History Data. You can use that. You can also use an App method to set Windows clipboard data. With these two nodes and a format into string you can program your vi to do what you want.

What if I have multiple charts from a dropdown menu? Will the history data node just hold values for the selected chart or for all the charts?

The property node is only for the chart that is referenced.  But the history will include all of the plots that are in that chart.

Is there a way to have only one plot from the chart?

Nevermind, I figured out a solution.

I will get a history data node for each plot from the chart and select each one from a case structure. Thanks for your help!
