INTRODUCTION
The WAVEFORM chart is a special type of numeric indicator that displays one or more plots of data typically acquired at a constant rate.
Waveform charts can display single or multiple plots. The below Figure shows the elements of a multiplot waveform chart. Two plots are displayed: Raw Data and Running Avg. The waveform chart maintains a history of data or buffer from previous updates.
DISPLAYING A SINGLE PLOT ON WAVEFORM CHARTS
You can wire a scalar output directly to a waveform chart. The waveform chart terminal shown in below Figure matches the input data type. If you pass the chart a single value or multiple values at a time, LABVIEW interprets the data as points on the
chart and increments the x index by one starting at x = 0. The chart treats these inputs as new data for a single plot. The waveform chart accepts the WAVEFORM DATA TYPE which carries the data, start time and delta t of a waveform.
