Automatically labeling plot legend using XY Graphs?

Question

I want to plot:
Time Amp
1       2
2       4
3       9
How do I get the legend to automatically say Amp, instead of Plot 0? I went to property node -> legend and I don't see any option
that would read the "column" header and label the legend accordingly.
In my example, the X array (Time) and Y array (Amp) are fed into Bundle which is then fed to the XY Graph input. The X array (1,2,3) and Y array (2,4,9)
obviously carry no information about their respective column names (Time, Amp). So, the legend must read this information separately, but I don't know
how to feed this information to the plot legend.

Answer 1

You simply need a property node for "plot.name". You have only one plot, so the following is sufficient (of course you would replace the string diagram constant with whatever you read from the column header in the file)
(If you have several plots, you would do it in a loop, setting the active plot from the iteration terminal, first, then writing the name)
Since this is an xy graph, I would actually hide the legend and simply label the two axes according to their header. This can be done in a similar way with property nodes. See if you can figure it out.
(Of course if the labels never change, enter them once manually and they will be saved with the VI. No code needed.)
