Re: CSS Boy scripting, clear XY-Graph automatically

[Hinxx <hinkocevar@gmail.com>]

Hi Christian,

if you attached the script to the button you should do something like 
this in your script ("GridWires" is the widget name set in CSS):
importPackage(Packages.org.csstudio.opibuilder.scriptUtil);

var w = display.getWidget("GridWires");
ConsoleUtil.writeInfo("widget: " + w);
w.clearGraph();
ConsoleUtil.writeInfo("widget: " + w + " cleared!");


Hope this helps,
Hinko
