Oscilloscope display


i’m looking for a possibility to display some analog values on the screen.
Colored graphs are easier to watch than flickering numbers.
A kind of an oscilloscope would be nice.
Are there any examples, apps or is everyone programming that for itself?

Take a look at @Roger Meier DataPlot class (http://opensource.the-meiers.org/)

Also @Christian Schmitz ChartDirector (https://www.monkeybreadsoftware.de/xojo/plugin-chartdirector.shtml)

I’ve used both and they are pretty good. I think DataPlot may serve you well (if you are familiar with Matlab-type plotting).

That looks great!
Maybe a little complex and a lot to read.
But a lot of good suggestions!
