I am developing a VI for Heart Rate Variability Analysis. I have plotted a Power spectrum Density plot. I however am not not able to select frequency ranges by sliding bars on the waveform graph. I would like to select a part of the displayed signal and process it (calculate power). It seems simple yet I cant get it. I think ti is to do with property node, but there are so many, I cannot figure out the right one.
You could try to create your own sliding bars, but I think it will be easier to simply use the built-in Graph Palette which contains a zoom tool to allow you to select ranges of a graph. Once it's zoomed in you can get the zoomed range from the XScale.Range.Minimum and XScale.Range.Maximum.
