Hi everyone,
I want to use SciChart to build an digital oscilloscope. For this aim I’m trying to set up a triggering-functionality for periodic signals. I didn’t find any information about this in the documentation and in the knowledgebase articles either. Does SciChart have such a function at all?
Thanks for your help,
Ralf

Hi Ralf,
We don’t actually have a trigger function built in to SciChart, think of what we do as just providing the front-end chart control and any underlying behaviours you can configure via our API.
For instance:
- You get your data from a source (e.g. data acquisition card)
- You cycle through your data and when a trigger (threshold) value is met you can append the next N-points as a window to the SciChart DataSeries
To append a window to a DataSeries is no more complex than calling DataSeries.Clear() followed by DataSeries.Append()
The number of points to append depends on the window size (e.g. 20 milliseconds) and the time-interval between samples.
We have a lot of Examples on repeatedly updating a dataseries.
Does this help?
