JFreeChart:缩放图表时添加和同步滚动条(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);
}

我想在用户放大时向我的图表添加滚动，但到目前为止我找到的所有示例(在演示包中，here 和其他来源)基于 Swing 处理 JPanes 和 ChartPanel.

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.

如何在我只有一个 Composite 的视图的 createPartControl() 函数中实现相同的功能.是否可以仅在 SWT 中执行，或者我应该将 SWT 与 SWING 或 AWT 混合(需要弄清楚如何)?

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

你可以看看SlidingXYDataset，在此处提到a>，或此处所示的分页方法.

You might look at SlidingXYDataset, mentioned here, or the paging approach shown here.
