## 场景 ##

Winforn中设置ZedGraph曲线图的属性、坐标轴属性、刻度属性：

Winform中实现ZedGraph的多条Y轴(附源码下载)：

添加多条曲线后，会默认生成不带任何Symbol的曲线，如果要修改其曲线的Symbol。

## 实现 ##

LineItem myCurve = myPane.AddCurve(yList[i].Title, DataChartHelper.SetCurveText(interval, xAttribute.TitleKey, yList[i].TitleKey), System.Drawing.ColorTranslator.FromHtml(yList[i].Color), SymbolType.None);

其中：

SymbolType.None

就是不带任何标志，如果要修改其标识。

SymbolType.Circle 圆形
    SymbolType.Default 正方形
    SymbolType.Diamond 菱形
    SymbolType.HDash 短横线
    SymbolType.Plus 加号
    SymbolType.Square 正方形
    SymbolType.None 没有
    SymbolType.Star 星号 *
    SymbolType.Triangle 等边三角形
    SymbolType.TriangleDown 倒等边三角形
    SymbolType.UserDefined 默认为正方形
    SymbolType.VDash 竖线
    SymbolType.XCross 叉号 ×

枚举变量对应的数字：

Square = 0,
    Diamond = 1,
    Triangle = 2,
    Circle = 3,
    XCross = 4,
    Plus = 5,
    Star = 6,
    TriangleDown = 7,
    HDash = 8,
    VDash = 9,
    UserDefined = 10,
    Default = 11,
    None = 12,

LineItem myCurve = myPane.AddCurve("曲线1", list1, Color.Red, SymbolType.Circle);
