Is there any limitation on number of pens we can add in power chart ? if i add 100 pens and then enable/disable them based on checkbox selection then is it okay ?
There's no hard limit. But as these power charts will run in a browser you'll start to have issues on displaying a huge amount of points and causing your browser to get very slow or crash.
Make sure to turn the point count way down on these trends if you do display this many.
Also I'm not sure how you'd colour 100 pens, You probably won't be able to tell the difference between them after about 20, but whether that matters or not is up to you.
Thanks. actually i show in one of the demo project(building automation demo project) they are enabled/disable with checkbox. i have try to use similar concept. you concern about colour 100 pens is valid and i have not thought about it yet but i think it can be changed during runtime also ?
it will never all 100 enable at a time. it will enable only which check box are ticked. and i would say out of 100 it will be 10 max at a time but just user will have flexibility to choose 10 from 100 pen.
