Java 为什么可以';我的CSV文件是否在我的图表上显示内容?
基本上,我的程序所做的是,我有一个csv文件,可以在 毫秒(我已转换)和表示区域的字母。我试图将其显示为条形图,但每个字母(区域)都有不同的选项卡。我的 问题是试图将信件(从文件)发送到我在选项卡中创建的特定区域。也许我遗漏了什么,但我不确定。任何帮助都将不胜感激 这是我的密码:Java 为什么可以';我的CSV文件是否在我的图表上显示内容?,java,swing,csv,Java,Swing,Csv,基本上,我的程序所做的是,我有一个csv文件,可以在 毫秒(我已转换)和表示区域的字母。我试图将其显示为条形图,但每个字母(区域)都有不同的选项卡。我的 问题是试图将信件(从文件)发送到我在选项卡中创建的特定区域。也许我遗漏了什么,但我不确定。任何帮助都将不胜感激 这是我的密码: @SuppressWarnings({ "serial", "deprecation" }) public class InductionTreeGraph extends JFrame { static TimeS

对于(int i=0,n=zones.length;i我的第一个建议是关于这条线:
setContentPane(chartPanel);
不要弄乱内容窗格。请改用此行:
getContentPane().add(chartPanel);
我在您的代码中看到的问题是,inclusiontreegraph
从JFrame
扩展而来,您将此chartPanel
设置为此框架的内容窗格,但随后使用新的JFrame
局部变量(称为frame
),并将此chartPanel
添加到此框架:
JFrame frame = new JFrame("Induction Zone Chart");
...
frame.getContentPane().add(chartPanel);
Swing组件旨在“按原样使用”,因此最好是继承而不是继承。已经说过,应该在类声明中考虑删除<代码>扩展jFrase>代码,并将所有组件(图表面板、按钮等)添加到本地“代码>帧< /COD>”。
