ThresholdSlider 

A ThresholdSlider is for the bar-like depiction of a state or an integer value. The color changes in accordance with defined threshold values. The interval between two of these Threshold values is a unit and the size of this interval is determined in pixels by the property unitWidth. A ThresholdSlider aggregates Thresholds. The Thresholds determine the color changes of the ThresholdSlider for example.

The total tooltip of the ThresholdSlider is ThresholdSlider.tooltip plus tooltip of the active Threshold.

The small markings under a ThresholdSlider are TickMarks, which help the underside of the ThresholdSlider to look like a ruler. You can use the showTickmarks property to determine whether these TickMarks should be shown or not. The distance in units between two TickMarks is determined by the TickMarkSpacing property.

The width of a ThresholdSlider is determined by the number of TickMark intervals, which is set by the maxTickMarks property. The width of a ThresholdSlider in Pixels can therefore be calculated as follows:

maxTickMarks * TickMarkSpacing * unitWidth
