Eclipse rcp 如何在RCP视图中更新jfree折线图

我在EclipseRCP应用程序中有四个视图。在该视图中，3个视图负责显示多行图。我使用开关盒连续绘制图形，直到其他视图聚焦。但该视图未显示更新的图表。 以下是更新图表的情况。我有两个数据集用于视图的示例更新

案例1：

System.out.println("in Case "+selectedViewId);
while(selectedViewId==1){
    try {
        Display.getDefault().syncExec(new Runnable() {
        public void run() {
        while(count<20) {
            count++;
            System.err.println("Countttttttt "+count);
            if(count%2==0){
                System.err.println(".....Oneeeeeeee");
                IViewPart vp =  PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().findView("RCP.CPU");
                PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().hideView(vp);
                PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().resetPerspective();
                try {
                    PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().showView("RCP.CPU");
                } catch (PartInitException e1) {
                    e1.printStackTrace();
                }
                int value = CPU.value=1;
                CPU cpuView = CPUSingleton.getCPUObject();
            }
            else {
                System.err.println(".....tWOOOOOOOOOOOOOO");
                IViewPart vp =  PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().findView("RCP.CPU");
                PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().hideView(vp);
                PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().resetPerspective();
                try {
                    PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().showView("RCP.CPU");
                } catch (PartInitException e) {
                    e.printStackTrace();
                }
                int value = CPU.value=2;
                CPU cpuView = CPUSingleton.getCPUObject();
            }
        }
        }
        });
    } catch (Exception e) {
        e.printStackTrace();
    }
}

break;
