How do i add a graph behind my waveform .

[visualrhythm]

This is what i'm trying to achieve .

anyone out there to help ? because i really don't get it .

What don't you get?  Your latest attachment shows you are plotting two waveforms simultaneously.

Are you just trying to get grid marks on your chart? If so just right click your chart and select properties. Select the scales tab>>y axies and click a color (T) on grid styles and colors major grid. The T designates transparent so choose white.

Hope this helps

I've seen that SupervisorsExample before. It's a homework assignment and the task is to make a VI work in a similar manner. The op's code is the VI called melvin. It seems there are several problems - including not having another plot.

Now i'm kind of stuck i still don't know how to make my temperature plot like this green line

You've got a working example and you have no clue how it works. One hint because I think the whole point of this is for you to learn LabVIEW. Right click on the plot legend. One of the options is how the points are connected.

What im trying to ask for is . for my temp plot . i need to make like curve shape similar to the supervisor example but i cannot use everything from there . but i dont know how .

Well, it looks like the plot interpolation is actually correct. The basic problem is the way you are generating the temperature value.
