JFreeChart - 创建移动图表时出现问题

2022-01-11 00:00:00 time-series java jfreechart

我在我的 java 应用程序中使用 JFreeChart.

I am using JFreeChart in my java application.

问题

我想绘制一个 XYAreaChart,当我们开始绘制数据时,它的 域轴(x 轴) 应该会自动水平滚动.

I want to plot a XYAreaChart whose domain axis (x-axis) should scroll horizontally automatically when we start plotting the data.

我在 TimeSeriesCharts 中看到了同样的内容,但我不想要任何 timeSeriesChart.我只想要滚动的 x 轴.

I saw the same thing in TimeSeriesCharts but I don't want any timeSeriesChart. I just want the scrolling x-axis.

推荐答案

您需要创建自己的 SlidingXYDataset 来实现 XYDataset 的方式类似于 SlidingCategoryDataset 实现 CategoryDataset.

You'll need to create your own SlidingXYDataset that implements XYDataset in a manner similar to how SlidingCategoryDataset implements CategoryDataset.

附录:如 评论中所述,一个典型的实现可以在here找到.

Addendum: As noted in a comment, a typical implementation can be found here.
