Ranges

In addition to the face and pointer ranges, gauges may contain additional ranges that show zones within the gauge (like 'bad', 'average', and 'good').

Depending on the setting of the showRanges property, these additional ranges may be shown at all times or used to determine the color of the pointer range based on the current gauge value.
