MSChart使用 对图形样式的部分设置,一般对series设置

使用雷达图样式:System.Web.UI.DataVisualization.Charting.SeriesChartType.Radar

            chart.ChartAreas[0].AxisX.Interval = 1;   //设置X轴坐标的间隔为1
            chart.ChartAreas[0].AxisX.IntervalOffset = 1;  //设置X轴坐标偏移为1
            chart.ChartAreas[0].AxisX.LabelStyle.IsStaggered = true;   //设置是否交错显示,比如数据多的时间分成两行来显示
