为了讲解方便,我先附上源代码和效果图。
代码如下:
using System;
using System.Drawing;
using System.Collections;
using ZedGraph;
namespace ZedGraph.Demo
{
///<summary>
/// Summary description for SimpleDemo.
///</summary>
public class InitialSampleDemo : DemoBase
{
public InitialSampleDemo() : base( "Code Project Initial Sample",
"Initial Sample", DemoType.Tutorial )
{
GraphPane myPane = base.GraphPane;
// Set the title and axis labels
myPane.Title = "My Test Graphn(For CodeProject Sample)";
myPane.XAxis.Title = "My X Axis";
myPane.YAxis.Title = "My Y Axis";
// Make up some data arrays based on the Sine function
PointPairList list1 = new PointPairList();
PointPairList list2 = new PointPairList();
for ( int i=0; i<36; i++ )
{
double x = (double) i + 5;
double y1 = 1.5 + Math.Sin( (double) i * 0.2 );
double y2 = 3.0 * ( 1.5 + Math.Sin( (double) i * 0.2 ) );
list1.Add( x, y1 );
list2.Add( x, y2 );
}
// Generate a red curve with diamond
// symbols, and "Porsche" in the legend
LineItem myCurve = myPane.AddCurve( "Porsche",
list1, Color.Red, SymbolType.Diamond );
// Generate a blue curve with circle
// symbols, and "Piper" in the legend
LineItem myCurve2 = myPane.AddCurve( "Piper",
list2, Color.Blue, SymbolType.Circle );
base.ZedGraphControl.AxisChange();
}
}
}
