请教一个绘制多图zedGraph的问题

pestlyn 2012-04-05 09:59:12

我在绘制一个多图的zedGraph的时候无法控制其中的的 GraphPane的高度和宽度，老是会出现图的纵坐标显示不全，各个图的大小不好控制的情况。
我现在想显示3个曲线图在一个控件上。前两个图的大小太大，最后一个图的大小又太小，求教各位啦。



private void Form1_Load(object sender, EventArgs e)

        {

            MasterPane master = zedGraphControl1.MasterPane;

            master.PaneList.Clear();

            master.Title.IsVisible = true;

            master.Title.Text = "感光电压曲线图";

            master.Margin.All = 10;

            master.InnerPaneGap = 0;

            ColorSymbolRotator rotator = new ColorSymbolRotator();

            for (int j = 0; j < 3; j++)

            {

                GraphPane myPaneT = new GraphPane(new Rectangle(40, 40, 500, 250),

                    "Case #" + (j+1).ToString(),
