您需要将
GantTrender
转换为setCompletePaint(c色)
,因此现在您要转换为Ballenderer
完整示例
添加图表自定义程序以获取JFreeChart
对象。(注意,您使用的集合已弃用)
我已经添加了标签jfreechart(这是使用的库)se例如this:Thanx用于回复,实际上我正在尝试更改进度条的颜色(任何任务的完成百分比),它在我的图表图像中是绿色的。如何更改此颜色?我正在使用动态报表api生成报表。在报告中,我需要实现甘特图。但是没有合适的文档来定制图表。所以,请检查这个链接,并帮助我,我如何才能做到这一点。基本上你需要在JFreeChart上搜索,这是你需要玩的对象,我已经给你一个答案,祝你玩得开心。。。。。
chart2.addCustomizer(new DRIChartCustomizer() {
private static final long serialVersionUID = 1L;
@Override
public void customize(JFreeChart chart, ReportParameters arg) {
//Here we got the JFreeChart object and we can modify it as we like
CategoryPlot plot = (CategoryPlot) chart.getPlot();
//Cast to GanttRenderer
GanttRenderer renderer = (GanttRenderer) plot.getRenderer();
//Set colors as desired.
renderer.setIncompletePaint(Color.CYAN);
renderer.setCompletePaint(Color.MAGENTA);
}
});
