我有6个以不同区域（A，B，C，S，SH，W）命名的选项卡，每个选项卡都显示来自csv文件的数据。在csv文件中，我有＃milliseconds列，我将其转换为Hour和minutes，另一列是Zone的字母（与制表符相同）。我可以在选项卡上显示数据，但它只是在一个选项卡中显示每个区域数据。我试图在每个标签中显示每个区域的数据。我该怎么做呢？我已经看过这个主题，但它没有解决我的问题：Adding ChartPanel to JTabbedPane using JPanel

答案 0 :(得分：2)
您有一个TimeSeries，ts的静态实例，您可以向其中添加所有数据。然后，您可以使用该单个实例创建每个图表面板。结果，图表都显示相同的数据。而是创建一个TimeSeriesCollection的单个实例，为每个区域添加TimeSeries。您可以将区域名称用作系列键，然后在构建每个图表面板时按名称检索每个系列。
顺便说一下，考虑编码到集合界面，例如
Map<String, Map<Integer, List<Integer>>> zoneMap = new TreeMap<>();
附录：我是否为每个区域创建了 TimeSeries ？
是。鉴于以下声明，
private static final String titles[] = {
"Zone A", "Zone B", "Zone C", "Zone S", "Zone SH", "Zone W"};
private final TimeSeriesCollection all = new TimeSeriesCollection();
您可以为每个区域的集合添加一个空系列，并使用区域名称作为每个TimeSeries的键。遇到CSV文件中的区域名称时，请按名称获取相应的TimeSeries并添加其数据。
private void createInduction() {
for (String s : titles) {
all.addSeries(new TimeSeries(s));
}
// while parsing the CSV file
String zone = …;
TimeSeries ts = all.getSeries(zone);
// add data to this zone's series
}
稍后，使用区域名称获取构建图表所需的数据集。
private ChartPanel createPane(String title) {
TimeSeriesCollection dataset = new TimeSeriesCollection(all.getSeries(title));
JFreeChart chart = ChartFactory.createXYBarChart(…. dataset. …);
// decorate chart
return new ChartPanel(chart);
}
最后，使用区域名称创建每个窗格。
private void display() {
…
JTabbedPane jtp = new JTabbedPane();
for (String s : titles) {
jtp.add(createPane(s));
}
…
}
