Basic Tutorials-section II: ModInitialSampleDemo.cs Introduction

In order to explain the convenience, I enclose the source code and the effect chart first.

The code is as follows:

Using System;

Using System.Drawing;

Using System.Collections;

Using Zedgraph;

Namespace Zedgraph.demo

{

Summary description for Simpledemo.

public class Modinitialsampledemo:demobase

{

Public Modinitialsampledemo (): Base ("Code Project Modified Initial Sample",

"Modified Initial Sample", demotype.tutorial)

{

Graphpane Mypane = base. Graphpane;

Set up 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);

Change the color of the title

MyPane.FontSpec.FontColor = Color.green;

ADD gridlines to the plot, and make them gray

MyPane.XAxis.IsShowGrid = true;

MyPane.YAxis.IsShowGrid = true;

MyPane.XAxis.GridColor = Color.lightgray;

MyPane.YAxis.GridColor = Color.lightgray;

Move the legend location

Base. Pane.Legend.Position = ZedGraph.LegendPos.Bottom;

Make both curves thicker

MyCurve.Line.Width = 2.0F;

MyCurve2.Line.Width = 2.0F;

Fill the area under the curves

MyCurve.Line.Fill = new Fill (Color.White, color.red, 45F);

MyCurve2.Line.Fill = new Fill (Color.White, Color.Blue, 45F);

Increase the symbol sizes, and fill them with solid white

MyCurve.Symbol.Size = 8.0F;

MyCurve2.Symbol.Size = 8.0F;

MyCurve.Symbol.Fill = new Fill (color.red);

MyCurve2.Symbol.Fill = new Fill (color.white);

Add a background gradient fill to the axis frame

Mypane.axisfill = new Fill (Color.White,

Color.FromArgb (255, 255, 210), -45f);

ADD a caption and an arrow

Textitem myText = new Textitem ("Interestingnpoint", 23F, 7F);

MyText.FontSpec.FontColor = color.red;

MyText.Location.AlignH = Alignh.center;

MyText.Location.AlignV = Alignv.top;

MYPANE.GRAPHITEMLIST.ADD (MyText);

Arrowitem Myarrow = new Arrowitem (color.red, 12F, 7F, 5F, 20F, 8F);

MYPANE.GRAPHITEMLIST.ADD (Myarrow);

Base. Zedgraphcontrol.axischange ();

}

}
