XY graph multiplot by "for" loop

[Joycezh]

Hi, All,

I have a questions about XY graph. Please kindly see the block diagram attached.

This question is from the same project and is similar to that I asked before: http://forums.ni.com/t5/LabVIEW/XY-graph-multiplot/m-p/1679222/highlight/true#M597705

However, now, at each iteration, the program will generate two sets of X-Y data: one measured and one fitted (polynomial fit to the measured data), and I wanted to plot all sets of X-Y data inside one graph.  According to the answers that I got from last thread, I am able to plot all the curves into one plot. However, this time is about the legend. How can I assign two plot names at each iteration-say after first iteration, the two curves should be "-1 measured" and "-1 fitted"? Right now, the result is as attached.

Thanks,

Joyce

Hi Joycezh,

I have a attached a link to a knowledge based article that describes how programmatically set the names of multiple plots.
