C＃的Winforms - 创建与多个Y轴的图表（3个或更多）(C# Winforms - Cre

我有一个需要使用图表超过2个Y轴的客户端。

我已经使用已经内置Y2轴和其工作部件中的一个（C1Chart）图

大。

做了图表控制，可以显示3以上的Y图表上轴的任何人都知道？

Answer 1:

微软图表控件样的环境中包含多个例如Y轴。
一些代码片段：

    private void checkBoxUseMultipleYAxis_CheckedChanged(object sender, System.EventArgs e)
    {
        if(checkBoxUseMultipleYAxis.Checked)
        {
            // Set custom chart area position
            Chart1.ChartAreas["Default"].Position = new ElementPosition(25,10,68,85);
            Chart1.ChartAreas["Default"].InnerPlotPosition = new ElementPosition(10,0,90,90);

            // Create extra Y axis for second and third series
            CreateYAxis(Chart1, Chart1.ChartAreas["Default"], Chart1.Series["Series2"], 13, 8);
            CreateYAxis(Chart1, Chart1.ChartAreas["Default"], Chart1.Series["Series3"], 22, 8);
        }
        else
        {
            // Set default chart areas
            Chart1.Series["Series2"].ChartArea = "Default";
            Chart1.Series["Series3"].ChartArea = "Default";

            // Remove newly created series and chart areas
            while(Chart1.Series.Count > 3)
            {
                Chart1.Series.RemoveAt(3);
            }
            while(Chart1.ChartAreas.Count > 1)
            {
                Chart1.ChartAreas.RemoveAt(1);
            }

            // Set default chart are position to Auto
            Chart1.ChartAreas["Default"].Position.Auto = true;
            Chart1.ChartAreas["Default"].InnerPlotPosition.Auto = true;

        }
    }

public void CreateYAxis(Chart chart, ChartArea area, Series series, float axisOffset, float labelsSize)
    {
        // Create new chart area for original series
        ChartArea areaSeries = chart.ChartAreas.Add("ChartArea_" + series.Name);
        areaSeries.BackColor = Color.Transparent;
        areaSeries.BorderColor = Color.Transparent;
        areaSeries.Position.FromRectangleF(area.Position.ToRectangleF());
        areaSeries.InnerPlotPosition.FromRectangleF(area.InnerPlotPosition.ToRectangleF());
        areaSeries.AxisX.MajorGrid.Enabled = false;
        areaSeries.AxisX.MajorTickMark.Enabled = false;
        areaSeries.AxisX.LabelStyle.Enabled = false;
        areaSeries.AxisY.MajorGrid.Enabled = false;
        areaSeries.AxisY.MajorTickMark.Enabled = false;
        areaSeries.AxisY.LabelStyle.Enabled = false;
        areaSeries.AxisY.IsStartedFromZero = area.AxisY.IsStartedFromZero;


        series.ChartArea = areaSeries.Name;

        // Create new chart area for axis
        ChartArea areaAxis = chart.ChartAreas.Add("AxisY_" + series.ChartArea);
        areaAxis.BackColor = Color.Transparent;
        areaAxis.BorderColor = Color.Transparent;
        areaAxis.Position.FromRectangleF(chart.ChartAreas[series.ChartArea].Position.ToRectangleF());
        areaAxis.InnerPlotPosition.FromRectangleF(chart.ChartAreas[series.ChartArea].InnerPlotPosition.ToRectangleF());

        // Create a copy of specified series
        Series seriesCopy = chart.Series.Add(series.Name + "_Copy");
        seriesCopy.ChartType = series.ChartType;
        foreach(DataPoint point in series.Points)
        {
            seriesCopy.Points.AddXY(point.XValue, point.YValues[0]);
        }

        // Hide copied series
        seriesCopy.IsVisibleInLegend = false;
        seriesCopy.Color = Color.Transparent;
        seriesCopy.BorderColor = Color.Transparent;
        seriesCopy.ChartArea = areaAxis.Name;

        // Disable drid lines & tickmarks
        areaAxis.AxisX.LineWidth = 0;
        areaAxis.AxisX.MajorGrid.Enabled = false;
        areaAxis.AxisX.MajorTickMark.Enabled = false;
        areaAxis.AxisX.LabelStyle.Enabled = false;
        areaAxis.AxisY.MajorGrid.Enabled = false;
        areaAxis.AxisY.IsStartedFromZero = area.AxisY.IsStartedFromZero;
        areaAxis.AxisY.LabelStyle.Font = area.AxisY.LabelStyle.Font;

        // Adjust area position
        areaAxis.Position.X -= axisOffset;
        areaAxis.InnerPlotPosition.X += labelsSize;

    }

结果：
