添加到MSChart的我想补充3 Y轴为以不同的比例图。如何更Y轴与不同的刻度在左侧或右侧
我想获得一个X轴和不同的Y轴。我做了类似下面的代码，但我想说明一个Y轴一样，我连着第二图像中..
我的C＃至今代码：
private void checkBoxUseMultipleYAxis_CheckedChanged(object sender, EventArgs e)
{
if (checkBoxUseMultipleYAxis.Checked)
{
// Set custom chart area position
chart1.ChartAreas["ChartArea1"].Position = new ElementPosition(25, 10, 68, 85);
chart1.ChartAreas["ChartArea1"].InnerPlotPosition = new ElementPosition(10, 0, 90, 90);``
// Create extra Y axis for second and third series
CreateYAxis(chart1, chart1.ChartAreas["ChartArea1"], chart1.Series["Current"], 13, 8);
CreateYAxis(chart1, chart1.ChartAreas["ChartArea1"], chart1.Series["Capacity"], 22, 8);
}
else
{
// Set default chart areas
chart1.Series["Current"].ChartArea = "ChartArea1";
chart1.Series["Capacity"].ChartArea = "ChartArea1";
// 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["ChartArea1"].Position.Auto = true;
chart1.ChartAreas["ChartArea1"].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;
}
};
你叫CreateYAxis两次，以创建两个additionY轴。相反，您可以将其中的一个放在次Y轴（右侧）。只是一个想法，既然你已经定制你的图表到这个扩展，你可以添加单独的图例/轴标题甚至注释和定位他们为指示目的。 – uqji
@ TaW，是的，代码不是我的，有些是由我改变的。我对这个更新。所以我不能维护我希望的代码。我想重新安排这个代码，就像我给出的第二张图片。要在图表区右侧获得容量轴。其他轴都可以。如果可以的话，请纠正它。它将有助于克服我的问题。感谢您的先生 – SNP
