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 show=
s 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 buf=
fer from previous updates.
DISPLAYING A SINGLE PLOT ON WAVEFORM CHARTS
You can wire a scalar output directly to a waveform chart. The waveform cha=
rt 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 t=
he data as points on the chart and increments the x index by one starting a=
t x =3D 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, star=
t time and delta t of a waveform.
