使用MsWeb图表的轴标签堆积柱形图

我正在使用Ms Web Chart来创建堆叠柱状图。如果列数<=9.如果它超过9，那么lables就不能正常出现。

for(int pointIndex = 0; pointIndex < 10; pointIndex++)
{
    Chart1.Series["Series1"].Points.AddY(Math.Round((double)random.Next(45, 95),0));
    Chart1.Series["Series2"].Points.AddY(Math.Round((double)random.Next(5, 75),0));
    Chart1.Series["Series3"].Points.AddY(Math.Round((double)random.Next(5, 95), 0));
    Chart1.Series["Series4"].Points.AddY(Math.Round((double)random.Next(35, 95), 0));
    Chart1.Series["Series1"].Points[pointIndex].AxisLabel = "test" + pointIndex;  
}
Chart1.Series["Series1"].ChartType = "StackedColumn";
Chart1.Series["Series2"].ChartType = "StackedColumn";
Chart1.Series["Series3"].ChartType = "StackedColumn";
Chart1.Series["Series4"].ChartType = "StackedColumn";

如果点索引小于=9，那么它就可以了。如果它>9，那么轴标签就可以正确地到达
