Setting Y-Axis Title from persistent global variable [message #976800]

I have a graph in a table. One of the detail rows is the column "Units". I have a persistent global variable name "Y_AXIS_UNITS". I set it onRender for that row. It works b/c I used it incorrectly to set the labels. I was using the method beforeDrawAxisLabel. Now I am using beforeDrawAxisTitle and I am trying to set the Y Axis Title to "Value <Units Value>". The problem is that normally to get the global variable I would normally use the following code:

value = context.getExternalContext().getScriptable().getPersistentGlobalVariable("Y_AXIS_UNITS")

However, the last method, getPersistentGlobalVariable is not available to me through icsc. How can I get this value and set the title? I have the following code:

beforeDrawAxisTitle( axis, label, icsc )
{
importPackage(Packages.org.eclipse.birt.chart.model.attribute);
   if(axis.getType() == AxisType.LINEAR_LITERAL)
   {
        label.getCaption().setValue("Units go here");
   }
}

It doesn't show it, but it's there.

icsc.getExternalContext().getScriptable().getPersistentGlobalVariable("varName"); should still get you what you're wanting.
