EasyChart Disctontinuous Digital

Hi !

Here I am again with a question about EasyChart:
I need to show some status (basic on/off) and see when there is data lost.
Is there a way to obtain a discontinuous digital pen ?
I tried the line w/ gaps and some adjusments on gap threshold, but it has not the digital look (and I don’t want to flood the database, it’s already 1 per 15s).
I searched a little in the JFreeChart doc but i didn’t find the digital part.

Thank you !
