dev ChartControl 备忘

一个chartControl 里包括以个diagram(图表)

diagram里可以设置 x-axis与y-axis ，另外还可以设置SecondaryXAxis与SecondaryYAxis,在Series属性里可以选择使用Secondary Axis

一个diagram里包括多少个Series，一个Series表示一组（x,y)取值集合

一个diagram里可以添加多个Panel, 二Series可以设置呈现在那个panel里

Series的主要属性是DataSource，指定 ArgumentDataMember(X-Axis),ValuesDataMembers(Y-Axis)

1.自定义标注显示内，首相要设置series.LablesVisibility=True

            chartControl1.CustomDrawSeriesPoint += (s, e) =>

            {

                if (e.Series == chartControl1.Series["Real"])

                {

                    var it = e.SeriesPoint;

                    var obj = it.Tag as QualifiedInfo; //Tag里是当前点的记录

                    e.LabelText = string.Format("{0}|{2}|{1}", obj.Disqualification, obj.Amount,obj.DisqualificationWithoutOtherDuty);

                }

            };
