篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了ZedGraph的常用属性相关的知识,希望对你有一定的参考价值。
前面有一篇文章介绍ZedGraph的官网,以及控件的使用文档。

现在,通过一个案例了解ZedGraph的常用属性。话不多数,直接上图。
这个是官网的一个案例,实现了多个Y轴同时在使用。
public partial class Form1 : Form
Graphpane myPane ;
PointPairList vlist ;
PointPairList alist ;
PointPairList dlist ;
PointPairList elist ;
YAxis yAxis3;
Y2Axis yAxis4;
public Form1()
InitializeComponent();
InitZedGraph();
btnNew.Click += new EventHandler(btnNew_Click);
#region 初始化图表控件
private void InitZedGraph()
myPane = myZedgraph.GraphPane;
myPane.Title.Text = "Domonstration of Multi Y Graph";
myPane.XAxis.Title.Text = "Time,s";
myPane.YAxis.Title.Text = "Velocity, m/s";
myPane.Y2Axis.Title.Text = "Acceleration, m/s2";

elist = new PointPairList();
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);
