Demonstrates how to add borders to sectors, and to set background and border colors for the sector label text boxes.
This example demonstrates how to add borders to sectors, and to set background and border colors for the sector label text boxes.
- The sector borders are set using PieChart.setLineColor.
- The sector label background and border colors are set using the Box.setBackground method of the TextBox object representing the sector label prototype. This TextBox object is returned by the PieChart.setLabelStyle method.
- The background color is set to SameAsMainColor, which means the background color is the same as the corresponding sector fill color.
