Issue Details

I am reading in amplitude and frequency data and want to display it on a sine wave graph in LabVIEW. 


Use the Simulate Signal function and select the type of wave you want to display. This function can simulate a sine wave, square wave, triangle wave, sawtooth wave, or noise signal. Drag the drop down arrows at the bottom of the function to display configuration options, such as amplitude and frequency, and wire your desired values here. To display your data, right click on the outgoing wire for type of wave you selected and select Create >> Graph Indicator. This will display your data on the front panel. 


Additional Information

You can also use the SubVIs Sine Wave and Sine Waveform to display frequency and amplitude data.
