篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Jfreechart柱状图如何让变成纯色相关的知识,希望对你有一定的参考价值。

这是我用freechart画的柱状图,柱子的颜色显得有点立体,如何让它变成纯色,就像下图:

BarRenderer renderer = new BarRenderer();

renderer.setBarPainter(new StandardBarPainter());

亲测有效!希望能帮到你!

参考技术A BarRenderer3D renderer = new BarRenderer3D();
renderer.setSeriesPaint(0, new Color(0, 0, 255));本回答被提问者和网友采纳
参考技术B 这个问题解决了吗?请教下
