求c#大神，Dev的chartControl画曲线图，x坐标不按顺序，3.5应该在3和4之间啊，这条线是最后一个画的，就这个效果，怎样才能画在他应该在的位置

Answer 1

Series series1 = new Series(this.Text, ViewType.Spline);
series1.ArgumentScaleType = ScaleType.DateTime;//x轴类型
series1.ValueScaleType = ScaleType.Numerical;//y轴类型
//X轴的数据字段
series1.ArgumentDataMember = "StatisticsTime";
//Y轴的数据字段
series1.ValueDataMembers[0] = "StatisticsSum";
//定义线条上点的标识形状是否需要
((LineSeriesView)series1.View).LineMarkerOptions.Visible = false;
//定义线条上点的标识形状
((LineSeriesView)series1.View).LineMarkerOptions.Kind = MarkerKind.Circle;
//不显示X、Y轴上面的交点的值
((PointSeriesLabel)series1.Label).Visible = false;
//线条的类型，虚线，实线
((LineSeriesView)series1.View).LineStyle.DashStyle = DashStyle.Solid;
