Chart/Graph for time-stamped data
> My LabVIEW version is 6.0.2. Will you inform me how to change dt
The key is to make the basic element a waveform rather than a scalar
number. If you currently have a scalar double wired to your chart, go
to the waveform palette and drop a Build Waveform node. This will allow
you to wire up a timestamp and a deltaTime. For single points, only the
timestamp is used. Doing this, you now have timestamped points and the
chart will place them on the time scale based upon this value. There
are a few assumptions such as -- time marches forward. A timestamp
before others written to the chart will clear the chart assuming that
you are starting over again.
If you are currently updating the chart with an array, you can drop the
same node and give the amplitudes a timestamp as well as a dT to
describe the time between the elements of the array.
If you currently have a cluster wired to the chart, take the point of
each cluster, make a waveform, and build an array of the waveforms.
If you currently have an array of clusters, then you will want to build
an array of waveforms similarly.
