Examples with IAxis org.swtchart.IAxis used on opensource projects

Example 1 with IAxis

use of org.swtchart.IAxis in project linuxtools by eclipse.

the class PieChart method setSeriesNames.

 * Sets this chart's category names such that the number of names
 * is equal to the number of pies. This method will only make changes
 * to category series if they are not already properly set.
 * @param numExpected The number of pies / the expected number of category names.
