ChartDirector 6.2 (.NET Edition)

Color Vertical Bar Meters


          

This example demonstrates horizontal bar meters in various colors, with different color scales, and with title and value readout.

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

The title and value readout are created as TextBox objects using BaseChart.addTitle and BaseChart.addTitle2, with the text box background set to the same color as that of the chart border.
