Drawing a chart with fast data

Good afternoon (o;

Played now around with the ChartDirector plugin but couldn’t get anything useful as there is pure no documentation for starting…especially the realtime chart example…

Is there another way to plot incoming data from USB in Xojo? Especially when data speed goes up to few 100k samples/sec?

Or has someone came across a good guide for ChartDirector plugin when it comes to real life data?

Last resort, and where I have more experience, is to do it again in PyQt5 (o;
But then again installation with all dependencies isn’t easy for other users knowing nothing about Python…so that’s why I wanted to give Xojo a try first.

thanks in advance
