MS 차트 여러 Y 축

Question

하나의 차트에 2 Y 축을 생성하는 방법이 있습니까?

같은 그래프에 2 축 이상을 추가하는 것은 불가능한 것처럼 보입니다.

실마리?

고마워요.

Answer 1

당신은 ... 마이크로 소프트에서 mschart samples를 다운로드하고

차트 기능 봐야한다 -> 축 -> 다중 Y 축의 여기

그것의 코드 추출

using System.Windows.Forms.DataVisualization.Charting; 
... 

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 area position to Auto 
    Chart1.ChartAreas["Default"].Position.Auto = true;
