TChart多纵坐标排开显示，怎么实现啊？

Answer 1

TeeChart6.0的pro版本就可以，CustomAxis, 你需要升级到这个版本。不过较大...

private Steema.TeeChart.Styles.FastLine fastLineSeries2;
private Steema.TeeChart.Styles.FastLine fastLineSeries3; private Steema.TeeChart.Axis Green;
private Steema.TeeChart.Axis Blue; public void tChart(Steema.TeeChart.TChart tChart,string headerName,string title1,string title2,string title3,DataTable dt,string x,string y1,string y2,string y3)
{
tChart.Header.Lines = new string[] {headerName};
Steema.TeeChart.Axis axis = tChart.TChart.Axes.Left;
axis.AxisPen.Color = Color.Red;
axis.StartPosition = 0;
axis.EndPosition = 30;
Green = new Steema.TeeChart.Axis();
tChart.Axes.Custom.Add(Green);
Green.AxisPen.Color = Color.Green;
Green.StartPosition = 34;
Green.EndPosition = 65;
Blue = new Steema.TeeChart.Axis();
tChart.TChart.Axes.Custom.Add(Blue);
Blue.AxisPen.Color = Color.Blue;
Blue.StartPosition = 70;
Blue.EndPosition = 100;
this.fastLineSeries1 = new Steema.TeeChart.Styles.FastLine();
this.fastLineSeries1.Cursor = System.Windows.Forms.Cursors.Cross;
this.fastLineSeries1.LinePen.Color = System.Drawing.Color.Red;
this.fastLineSeries1.Title = title1;
this.fastLineSeries1.XValues.Order = Steema.TeeChart.Styles.ValueListOrder.Ascending;
this.fastLineSeries1.VertAxis = Steema.TeeChart.Styles.VerticalAxis.Left; this.fastLineSeries2 = new Steema.TeeChart.Styles.FastLine();
this.fastLineSeries2.Cursor = System.Windows.Forms.Cursors.Cross;
this.fastLineSeries2.LinePen.Color = System.Drawing.Color.Green;
this.fastLineSeries2.Title = title2;
this.fastLineSeries2.XValues.Order = Steema.TeeChart.Styles.ValueListOrder.Ascending;
this.fastLineSeries2.CustomVertAxis = Green; this.fastLineSeries3 = new Steema.TeeChart.Styles.FastLine();

this.fastLineSeries3.Title = title3;
this.fastLineSeries3.XValues.Order = Steema.TeeChart.Styles.ValueListOrder.Ascending;
this.fastLineSeries3.CustomVertAxis = Blue; tChart.Series.Add(fastLineSeries1);
tChart.Series.Add(fastLineSeries2);
tChart.Series.Add(fastLineSeries3);
fastLineSeries1.DataSource = dt;
fastLineSeries1.LabelMember = x;
fastLineSeries1.YValues.DataMember = y1; fastLineSeries2.DataSource = dt;
fastLineSeries2.LabelMember = x;
fastLineSeries2.YValues.DataMember = y2; fastLineSeries3.DataSource = dt;
fastLineSeries3.LabelMember = x;
fastLineSeries3.YValues.DataMember = y3;
}

追问

看不懂啊，我只会C++。
你这里到底定义了几根Y轴啊？

你用TChart做啥啊？

你自己改着用吧，建议你去找TChart手册看看
void InitChart(TChart *Chart)
{
#define YAXIS_WIDTH 40
char Buf[256];
int Color,ColorList[]={clRed,clBlue,clGreen};
int VisibleYAxis=0;
TChartAxis *YAxis;
TFastLineSeries *Series;
for( int n = 0;n < 3;n++)
{
Color=ColorList[n];
YAxis=new TChartAxis(Chart->CustomAxes);
YAxis->Maximum=100;
YAxis->Minimum=0;
YAxis->Automatic=false;
YAxis->Axis->Color=Color;
YAxis->Axis->Width=1;
YAxis->LabelsAngle=90;
YAxis->LabelsFont->Color=Color;
YAxis->Ticks->Color=Color;
sprintf(Buf,"YAxis%d",n);
YAxis->Title->Caption=Buf;
YAxis->Title->Font->Color=Color;
YAxis->Title->Angle=90;
YAxis->MinorGrid->Visible=false;
YAxis->Grid->Visible=false;
YAxis->PositionUnits=muPixels;
YAxis->PositionPercent=-YAXIS_WIDTH*VisibleYAxis;
VisibleYAxis++;
Series = new TFastLineSeries(Chart);
Series->Color=Color;
Series->LinePen->Width=1;
Series->CustomVertAxis=YAxis;
Series->XValues->DateTime=true;
Chart->AddSeries(Series);
}
Chart->BottomAxis->DateTimeFormat="hh:nn:ss:zzz";
Chart->BottomAxis->Grid->Visible=false;
Chart->MarginUnits=muPixels;
Chart->MarginLeft=YAXIS_WIDTH*VisibleYAxis;
}
