Color Semicircle Meters


          

This example demonstrates semicircle meters in various gradient colors, as well as various color scales and pointer types.

The background color in this example changes from a specified color at the border, to a brighter version of the color at the center. The brighter color is derived from the specified color using BaseChart.adjustBrightness. To achieve the radial gradient effect, these two colors are passed to AngularMeter.relativeRadialGradient to create a radial gradient color. The gradient color is then passed to AngularMeter.addScaleBackground to fill the background.

BaseMeter.addColorScale is used to create the color scales in this example. The color scales are created by with different colors, different end point positions and different widths at the end points.

Two pointer types are shown in these meters - a sharp very thin triangular pointer, and a line pointer. They are created using AngularMeter.addPointer2 with TriangularPointer2 and LinePointer2 as parameters.
