Zedgraph，不止一根柱

Question

我正在尝试用 zedgraph 制作一个 stackedbar 。我使用了在本网站的一个问题中找到的一些编码示例。我做了一些改变，但我无法让我按照我想要的方式工作。图表上的输出是相互堆叠的条形。当该方法第二次运行时，第一次的柱仍然存在，并且新的柱构建在旧柱的顶部。

想要的输出：我想看到列表中每个整数的堆积条。但必须确保 listA 中的第一个整数与 listB 中的第一个整数位于同一柱上。

        zedGraphControl1.GraphPane.CurveList.Clear();
        zedGraphControl1.GraphPane.GraphObjList.Clear();
        //I want to clear my chart, and write a new one. I dont think the above works??^^^

        GraphPane myPane = zedGraphControl1.GraphPane;

        myPane.BarSettings.Type = BarType.PercentStack;
        myPane.XAxis.Type = ZedGraph.AxisType.Date;

        PointPairList PPLa = new PointPairList();
        PointPairList PPLb = new PointPairList();
        PointPairList PPLc = new PointPairList();
        PointPairList PPLd = new PointPairList();
        PointPairList PPLf = new PointPairList();
        List<int> listA = new List<int>();
        List<int> listB = new List<int>();

        int Max = listA.Count;
        //^^ I've made this line to control how many times the loop should run.

        for (int i = 0; i < Max; i++)
        {

            }

            int som3;
            for (som3 = 0; som3 <= (listC.Count - 1); som3++)
            {
                int c = listC[i];
                PPLc.Add(date, (double)c);

            }

            int som4;
            for (som4 = 0; som4 <= (listD.Count - 1); som4++)
            {
                int d = listD[i];
                PPLd.Add(date, (double)d);

            }

            int som5;

            {
                int f = listF[i];
                PPLf.Add(date, (double)f);

            }



            BarItem myBara = myPane.AddBar("A", PPLa, Color.Red);

            BarItem myBarf = myPane.AddBar("F", PPLf, Color.Pink);


            zedGraphControl1.AxisChange();



        }
        zg1.AxisChange();

    private void graph2()
    {
        zedGraphControl1.GraphPane.CurveList.Clear();
        zedGraphControl1.GraphPane.GraphObjList.Clear();
        // clearing not tested

        GraphPane myPane = zedGraphControl1.GraphPane;

        myPane.BarSettings.Type = BarType.PercentStack;
        //      myPane.XAxis.Type = ZedGraph.AxisType.Date;
        // Date wont work in our case

        PointPairList PPLa = new PointPairList();
        PointPairList PPLb = new PointPairList();

        }
        // above is used to fill up the lists (for example)
        // be aware that listA[0] = 0 for i = 1, (will be vissible in chart)


        // when you us < instead of <= you dont need a listA.Count - 1
        // below is not failsafe, if any list is smaller than listA an error may appear
        // this is just a sample so i thought it wouldnt matter
        for (int i = 0; i < listA.Count; i++)
        {

    }

Answer 2

我做的（一个）Zedgraph 项目，我总是做类似的事情：

master = zedGraphDruck.MasterPane;
master.GraphObjList.Clear();
master.PaneList.Clear();
GraphPane g = new GraphPane(gpr, titel, null, null);
...
master.Add(g);
zedGraphDruck.AxisChange();
zedGraphDruck.Invalidate();

gpr 是一个（新）矩形，具有所需的大小和标题字符串；
