xy graph to xy chart

[Perykin]

I need work with a xy graph and at the same time, I need to see point to point's graphicaton like in a waveform chart.
How can I do it? I think that using global variables it is posible, but, how???

I'm not exactly sure what you mean by "point to point's graphicaton like in a waveform chart", but there are a couple of shipping examples that make an XY graph act like a chart as far as incremental updates, scrolling, etc. They are called Variable-Time Chart XY and XY Chart. Select Help>Find Examples, click the Search tab and enter XY as the keyboard to find them.
