如何在Zedgraph中同步选定窗格的X轴?

[英]How to Synchronize X Axis of Selected Panes in Zedgraph?

我正在尝试同步Zedgraph中选定窗格的X轴,

目前,我有三个窗格:

在此处输入图片说明

借助follwoing属性,我可以同步所有可用窗格的X轴:

zedGraphControl1.IsSynchronizeXAxes = true;

但我只想同步Pane-1和Pane-3 ,可以吗?

非常感谢您的时间... :)

  1. 项目清单

是的。

基本上,您必须挂钩到ZoomEvent,然后使用FindPane捕获已平移或缩放的窗格,将其Scale Min和Max属性应用到其他AxisChange如果将其他一些Scale属性设置为Auto ,则执行AxisChange

假设要排除的GraphPane对象被excludedGraphPane

void zedGraphControl1_ZoomEvent(ZedGraph.ZedGraphControl z, ZedGraph.ZoomState oldState, ZedGraph.ZoomState newState)
{
    GraphPane pane;

    using (var g = z.CreateGraphics())
        pane = z.MasterPane.FindPane(z.PointToClient(MousePosition));

    // The excludedGraphPane has to remain independant
    if (pane == null || pane == excludedGraphPane)
        return;

    foreach (var gp in z.MasterPane.PaneList)
    {
        if (gp == pane || gp == excludedGraphPane)
            continue;

        gp.XAxis.Scale.Min = pane.XAxis.Scale.Min;
        gp.XAxis.Scale.Max = pane.XAxis.Scale.Max;
        gp.AxisChange(); // Only necessary if one or more scale property is set to Auto.
    }

    z.Invalidate();
}

当然,由于同步现在是手动完成的,因此您需要设置

zedGraphControl1.IsSynchronizeXAxes = false;
