Slowly but surely, things are starting to gel...

Next, can I display a meter with more than one needle (Or is that just displaying several meters at the same location?)?

Have a situation where I need to display 3 variables with the same comparative scale. The comparison between the indicators is important, so I want to display all 3 meters on the same dial face.

You can add as many RTMeterNeedleIndicator objects to a chart as you want. If they reference the same meter frame they will appear in the same meter.

RTMeterNeedleIndicator meterneedle1 = new RTMeterNeedleIndicator(meterframe1, processVar1);
...
RTMeterNeedleIndicator meterneedle2 = new RTMeterNeedleIndicator(meterframe1, processVar2);
...
RTMeterNeedleIndicator meterneedle3 = new RTMeterNeedleIndicator(meterframe1, processVar3);
...

chartVu.addChartObject(meterneedle1);
chartVu.addChartObject(meterneedle2);
chartVu.addChartObject(meterneedle3);
