如何在MS图表中为多个系列添加图例C＃

Question

我一直在从事ASP.NET MVC剃须刀项目，C＃，Visual Studio2012。我有一个包含两个系列的图表。

我的代码是：

var chartCentersByYear = new Chart
            {
                Width = 1000,
                Height = 450,
                RenderType = RenderType.ImageTag,
                AntiAliasing = AntiAliasingStyles.Graphics,
                TextAntiAliasingQuality = TextAntiAliasingQuality.High


            };

            chartCentersByYear.Series.Add("Count");
            chartCentersByYear.Series.Add("Cases");
            chartCentersByYear.Series[0].ChartType = SeriesChartType.Column; 
            chartCentersByYear.Series[1].ChartType = SeriesChartType.Line;
var totalCentersByYearResult = new Repository().GetTotalCentersByYear();

            foreach (IGD_spInternationalReportCenterWithTots_Result item in totalCentersByYearResult)
            {
                chartCentersByYear.Series[0].Points.AddXY(item.YearEcmo, item.Count);
                chartCentersByYear.Series[1].Points.AddY(item.Cases);
            }

...等等。 我必须在图表中插入图例以在同一图例中显示两个系列。 我需要在图例符号旁边显示值，每年用于计数83,86,93 ...等，对于案例1644,1775,1933等。 我怎样才能做到这一点？ 预先感谢您的任何帮助。

Answer 1

Legend secondLegend = new Legend("MyLegend");

this.Chart1.Legends.Add("MyLegend");

// Associate Series 2 with the second legend 
chartCentersByYear.Series[0].Legend = "MyLegend";
chartCentersByYear.Series[1].Legend = "MyLegend";
chartCentersByYear.Series[2].Legend = "MyLegend";
chartCentersByYear.Series[3].Legend = "MyLegend";
