JFreeChart：在缩放图表时添加并同步一个滚动条（Eclipse插件/ SWT） [英] JFreeChart: Add and sync a srollbar when zooming a chart (Eclipse plugin / SWT)

问题描述

我正在使用JFreeChart库在Eclipse视图中绘制一些东西，目前我的视图初始化代码如下所示：

I am using JFreeChart library to plot something in an Eclipse view and currently my code for view initialization looks as follows:

@Override
public void createPartControl(Composite parent)
{
    JFreeChart chart = null;

    // Created via different object     
    chart = graph.createLineChart("Test Graph", "x", "y");

    ChartComposite frame = new ChartComposite(parent, SWT.NONE, chart, true);
    frame.setRangeZoomable(false);      
    parent.layout(true);
}

当用户放大时，我想添加滚动到我的图形，但是我发现的所有例子（在演示包中，这里和其他来源）基于Swing处理JPanes和ChartPanels。

I wanted to add scrolling to my graph when the user zooms in, but so far all the examples that I found (in the demo package, here, and other sources) are based on Swing dealing with JPanes and ChartPanels.

如何在 createPartControl（）我的视图功能，我只有一个复合。是否可以在SWT中进行，或者应该将SWT与SWING或AWT混合使用吗？

How can I achieve the same in the createPartControl() function of my view where I have only a Composite. Is it possible to do it in SWT only or should I mix (need to figure out how) SWT with SWING or AWT?

谢谢
