JFreeChart - 创建移动图表时出现问题
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.
