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 XYAreaChart ,当我们开始绘制数据时,域轴(x轴)应自动水平滚动。
I want to plot a XYAreaChart whose domain axis (x-axis) should scroll horizontally automatically when we start plotting the data.
我在 TimeSeriesCharts 中看到了相同的内容,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.
你需要创建自己的 SlidingXYDataset
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
.
Addendum: As noted in a comment, a typical implementation can be found here.
