IsHStack
当有多个显示项的时候设置 Y 轴数据是叠加的还是分开的
Xaxis
图表区域的 X 轴相关信息设置

Cross
坐标的原点，可以设置坐标的偏移程度

IsImageMap
不清楚干吗用的
AxisChaneged
是否允许自动绘图（没试过，一般都 true，动态绘图）
CacheDuration
Cache 保存时间0
OutputFormat
输出格式
RenderedImagePath
输出路径
RenderMode
输出模式，不太清楚一般都是 ImageTag，另一个输出的是乱码不是图片。对于图表而言，一般是三种表现形式：柱状图、饼状图和点线图。
//-----------------------------------------------------------//附：在vs中使用ZedGraph控件的一些记录（转）
//
//几个注意点：
//
//图片的保存路径设置：RenderedImagePath 属性中设置，程序对该文件夹应该是有写和修改权限的
//
//图片的输出格式：OutputFormat 属性中设置，Png 的推荐，比较清晰。
//myPane.YAxis.MajorGrid.IsZeroLine = false; // Don't display the Y zero line
// (填充数据点)
// myCurve.Symbol.Fill = new Fill(Color.White);
//声明画笔
//GraphPane myPane = zgc.GraphPane;
// 设定坐标组
//PointPairList list1 = new PointPairList();
//zgc.PointValueEvent += new ZedGraphControl.PointValueHandler(MyPointValueHandler); //修改右键
//先清除
//zedChart.GraphPane.CurveList.Clear();
//zedChart.GraphPane.GraphItemList.Clear();
//重新绘制
//zedChart.AxisChange();
//zedChart.Refresh();
//刷新控件
