GaugeMarkerBase.calcOffset

Syntax

calcOffset ();

Description

The calcOffset method calculates radial offset from the scale center.

Example

To execute the example, the page must contain the Speedometer component named speed1 (see Example of Creating a Fuel Gauge Unit). Add to the page a button, clicking which shows values of speedometer parameters:

<input TYPE="button" VALUE="Calc" ONCLICK="calc()">
<script>
function calc()   
{
	var arrow = speed1.getScales(0).getArrows(0);
	var marker = speed1.getCenter();
	var str = "GaugeArrowBase.calcRadius() = " + arrow.calcRadius() + "\n";
	str += "GaugeMarkerBase.calcSize() = " + marker.calcSize() + "\n";
	str += "GaugeMarkerBase.calcOffset() = " + marker.calcOffset() + "\n";
	alert(str);
}
</script>

Clicking the Calc button shows a message that contains values of speedometer parameters, returned by the calcRadius, calcSize, and calcOffset methods:

GaugeArrowBase.calcRadius() = 140

GaugeMarkerBase.calcSize() = 17

GaugeMarkerBase.calcOfset() = 0
