Winform中设置ZedGraph的曲线为折线、点折线、散点图

场景

在上面设置单条曲线为散点图后的思路，继续扩展设置曲线为折线、点折图、散点图。

效果

注：

实现

读取配置文件内容获取设置的曲线样式后

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

根据配置文件设置曲线类型

myCurve = setCurveType(myCurve, yList[i].Type, yList[i].Color);

然后调用设置曲线样式的方法，在方法里

private static LineItem setCurveType(LineItem myCurve, string p,string color)
        {
            switch(p)
            {
                case "折线":
                    myCurve.Symbol.Type = SymbolType.None;
                    myCurve.Line.IsVisible = true;
                    break;
                case "点折线":
                    myCurve.Symbol.Type = SymbolType.Circle;
                    myCurve.Symbol.Fill = new Fill(System.Drawing.ColorTranslator.FromHtml(color));
                    myCurve.Symbol.Size = 3;
                    break;
                case "点离散":
                    myCurve.Symbol.Type = SymbolType.Circle;
                    myCurve.Symbol.Fill = new Fill(System.Drawing.ColorTranslator.FromHtml(color));
                    myCurve.Symbol.Size = 3;
                    myCurve.Line.IsVisible = false;
                    break;
                default :
                    myCurve.Symbol.Type = SymbolType.None;
                    myCurve.Line.IsVisible = true;
                    break;

            }
            return myCurve;
        }
