Java jfreechart stick scatterplot？ [英] Java jfreechart stick scatterplot?

问题描述

我现在正在使用jfreechart，想要生成一种散点图。我有100000个数据点。现在我想通过将点z值作为杆高度将每个2D点更改为（3D-）杆。整个情节应该是可缩放的！
多数民众赞成吧。这可能在jfreechart中吗？
我怎样才能在缩放动作中没有屈服或延迟？

感谢您的任何建议！

对于~10 ⁶ 数据点， FastScatterPlot 是个不错的选择。对于较大的数字，你必须进行测试。

附录：好消息是缩放效果非常好，你可以根据需要设置初始缩放区域。 / p>

附录：对于速度， FastScatterPlot 使用内部 render（） 方法，而不是插件渲染器。不要渲染形状，而应考虑使用饱和度或透明度不同的颜色光谱。

I am using jfreechart at the moment and want to generate a kind of scatterplot. I have 100000s of datapoints. Now I want to change each 2D point into a (3D-) stick by usind the points z-value as the stick height. The whole plot should be zoomable! Thats it. Is this possible in jfreechart? How can I do this without bucking or delay within the zooming action?

Thanks for any suggestions!

解决方案

For ~10⁶ data points, FastScatterPlot is a good choice. For larger numbers, you'll have to test.

Addendum: The good news is that zooming works very well, and you can set the initial zoom area as needed.

Addendum: For speed, FastScatterPlot uses an internal render() method, instead of a plug-in renderer. Rather than rendering a shape, consider using a spectrum of colors that vary in saturation or transparency.
