Hi, I am outputting data from a spectrometer onto a graph and wanted to add some vertical lines in the background to designate the peaks I am looking for. I was able to to use the "plot images: back" property node and "map xy to coordinates" but how do I draw lines not starting from the origin? Any suggestions are appreciated.
it depends on what graph you are using; for XY you can add something like (x1, y1), (x1, y2), (nan, nan), and so on,...the height of the line would be y2-y1
Thanks for the reply. The problem is that I'm using a waveform graph and the input to the "draw line vi" is the endpoint. I'm not sure how to start the line anywhere other than the origin.
