QUOTE(torekp @ Apr 16 2007, 10:00 AM) It is not exactly what I need to do, because there is the necessity to plot many lines, not only one like in the example. Following the way of example, I got it, using the wave chart graph, but I need independent auxiliaries lines. Any ideas? Thank you.

I am in trouble with a multi plot graph. There is a wave chart, and I have to plot an auxiliary line when the user clicks over the graphic. I know how to get the initial point and the final point of the auxiliar line, I get the Y scale range and X absolute value, in other words, the X value of the place that I click. My doubt is in how can I plot this auxiliary line in the same graph? There is no problem if I have to use another labView object to do this task. Any ideas, sugestions or examples? Thank you in advance
