XYPlot.datasetChanged介绍

[英]Receives notification of a change to the plot's dataset.

The axis ranges are updated if necessary.
[中]接收绘图数据集更改的通知。
如有必要，将更新轴范围。

代码示例

public void updateChart() {
  // synchronized (plot) {
  plot.datasetChanged(new DatasetChangeEvent(this, series));
  lastUpdate = System.currentTimeMillis();
  // }
}
