Answer 2

简单折线图显示去年销售额与今年销售额的条形图。

        chart1.Series.Clear();

        string[] months = { "Jan", "Feb", "Mar", "Apr" };
        double[] thisYearSales = { 10000.23, 98000, 95876, 78097 };
        double[] lastYearSales = { 99000, 99000, 90876, 88097 };

        Series thisYear = chart1.Series.Add("this year");
        thisYear.Points.DataBindXY(months, thisYearSales);

        Series lastYear = chart1.Series.Add("last year");
        lastYear.Points.DataBindXY(months, lastYearSales);
        lastYear.ChartType = SeriesChartType.Line;
