C# 有没有3坐标的图表控件？
2坐标的可以用ZedGraph，不知道三坐标的有没有比较好用的控件
不求多复杂，只做简单的显示，谢谢

------解决方案--------------------
3坐标得zedgraph也可以做得。
------解决方案--------------------
核心代码：zedgraph得：
GraphPane myPane = base.GraphPane;

// Set the titles and axis labels
myPane.Title.Text = "Demonstration of Multi Y Graph";
myPane.XAxis.Title.Text = "Time, s";
myPane.YAxis.Title.Text = "Velocity, m/s";
myPane.Y2Axis.Title.Text = "Acceleration, m/s2";

// Make up some data points based on the Sine function
PointPairList vList = new PointPairList();
PointPairList aList = new PointPairList();
PointPairList dList = new PointPairList();
PointPairList eList = new PointPairList();

// Fabricate some data values
for ( int i=0; i<30; i++ )
{
double time = (double) i;
double acceleration = 2.0;
double velocity = acceleration * time;
double distance = acceleration * time * time / 2.0;
double energy = 100.0 * velocity * velocity / 2.0;
aList.Add( time, acceleration );
vList.Add( time, velocity );
eList.Add( time, energy );
dList.Add( time, distance );
}

// Generate a red curve with diamond symbols, and "Velocity" in the legend
LineItem myCurve = myPane.AddCurve( "Velocity",
vList, Color.Red, SymbolType.Diamond );
// Fill the symbols with white
myCurve.Symbol.Fill = new Fill( Color.White );

// Generate a blue curve with circle symbols, and "Acceleration" in the legend
myCurve = myPane.AddCurve( "Acceleration",
aList, Color.Blue, SymbolType.Circle );
// Fill the symbols with white
myCurve.Symbol.Fill = new Fill( Color.White );
// Associate this curve with the Y2 axis
myCurve.IsY2Axis = true;

// Generate a green curve with square symbols, and "Distance" in the legend
myCurve = myPane.AddCurve( "Distance",
dList, Color.Green, SymbolType.Square );
// Fill the symbols with white
myCurve.Symbol.Fill = new Fill( Color.White );
// Associate this curve with the second Y axis
myCurve.YAxisIndex = 1;

// Generate a Black curve with triangle symbols, and "Energy" in the legend
myCurve = myPane.AddCurve( "Energy",
eList, Color.Black, SymbolType.Triangle );
// Fill the symbols with white
myCurve.Symbol.Fill = new Fill( Color.White );
// Associate this curve with the Y2 axis
myCurve.IsY2Axis = true;
// Associate this curve with the second Y2 axis
myCurve.YAxisIndex = 1;

// Show the x axis grid
myPane.XAxis.MajorGrid.IsVisible = true;

// Make the Y axis scale red
myPane.YAxis.Scale.FontSpec.FontColor = Color.Red;
myPane.YAxis.Title.FontSpec.FontColor = Color.Red;
// turn off the opposite tics so the Y tics don't show up on the Y2 axis
myPane.YAxis.MajorTic.IsOpposite = false;
myPane.YAxis.MinorTic.IsOpposite = false;
// Don't display the Y zero line
myPane.YAxis.MajorGrid.IsZeroLine = false;
// Align the Y axis labels so they are flush to the axis
myPane.YAxis.Scale.Align = AlignP.Inside;
myPane.YAxis.Scale.Max = 100;

// Enable the Y2 axis display
myPane.Y2Axis.IsVisible = true;
// Make the Y2 axis scale blue
myPane.Y2Axis.Scale.FontSpec.FontColor = Color.Blue;
myPane.Y2Axis.Title.FontSpec.FontColor = Color.Blue;
// turn off the opposite tics so the Y2 tics don't show up on the Y axis
myPane.Y2Axis.MajorTic.IsOpposite = false;
myPane.Y2Axis.MinorTic.I
