You can modify an example to fit an application, or you can copy and paste from one or more examples into a VI that you create. Labview provides common visualization elements and functions for measurement data (such as strip chart recorders), which must be reinvented in other languages. Next, create a MainWindow and add the following code:Try to use the array to cluster function on your 1D array and wire that into your waveform chart. The only thing that makes this a "real-time" chart is that the x axis is displaying. I've been programming LV for years, but have never done much with strip charts. Options.
