LabVIEW
How can I plot multiple curves using the XY graph?
Your graph is only showing the last point(s) because that's all you're feeding it. Just because you build a single point into an array doesn't make the array bigger. Now it's an array with one data point rather than a scalar. To the graph there's no difference. What you want to do is to expand those build arrays and concatenate the new data into arrays coming from a shift register. That way you have a history building up that gets plotted each iteration.
EDIT: Be aware that concatenating into an array like this is memory inefficient. There's not much choice when you have unknown amounts of data coming in but it's something to be aware of. If a VI like this runs for long periods you may run out of memory because of the copies LabVIEW will make in the name of data security. There are numerous threads on the subject.

Sorry, I am not familiar with the simulation toolkit, but tthere are a couple of things that don't make sense.
Why is there a FOR loop with 1 iteration and autoindexing outputs? That adds another dimension to your plot data without adding new data. remove it!
Each wire data seems to be a cluster of x and y arrays, directly compatible with an xy graph. To create an xy multiplot with all three, simply form an array fo these clusters.
Hello,
I don't understand why you are using a for loop with one iteration. Just collect the signals you want to display into an array and use either the simulation time waveform or the collector with an XY graph.
Hope this helps.
It looks like the problem is in your cluster to graph sub-vi.
I have replicated your code here (creating dummy xy data in the for loops). Notice the difference in the thickness of the pink lines when compared to the images you posted. Without seeing your code, I am guessing that you have overcomplicated the data formatting in the sub-vi.
