thickness property

dynamic thickness
getter/setter pair

In a gauge chart, this option sets the width of the plot band stretching along the perimeter. It can be given as a percentage string, like "10%", or as a pixel number, like 10. The default value 10 is the same as the default tickLength, thus making the plot band act as a background for the tick markers.
