Gauges
A number of different gauge types are available within the gauge series type and can be specified by the Series.GaugeType property. Each series on a gauge chart can use a different gauge type setting.
Automatic Padding Feature

Generally many of these gauge types are used by themselves without a legend or other features. When the chart detects that the legend is not visible and the chart area is not drawn (by using ChartArea.ClearColors()), it will automatically get rid of additional padding around the gauge.
