jSP中做ppt图 表时的一个小问题

Question

我做了一共横纵类型的PPT图表，但现在出现了一个问题就是横轴下的汉字标识格式不满意，现在的样式是“第一季度”而我希望汉字能够竖排如下
第
一
季
度
请问怎么搞啊
目前的代码是
oChart1 = ChartSpace2.Charts.Add();
oChart1.HasTitle = true;
oChart1.Title.Caption = "<%="分布情况"%>";
                        oChart1.Title.font.name="楷体";
                        oChart1.Title.font.color="yellow";
                        oChart1.Title.font.bold=true;
                        oChart1.Title.font.size=20;
oChart1.Type = c2.chChartTypeColumnClustered3D;                        oChart1.border.Color = "#ffffff";
                       var yValueAxis = ChartSpace2.Charts(0).Axes(c2.chAxisPositionValue);
                       yValueAxis.MajorUnit = 500;
                       yValueAxis.MajorGridlines.Line.Color = "#ffffff";
                       yValueAxis.font.bold=true;
                       yValueAxis.font.size=12;
                       yValueAxis.font.color="white";
                       yValueAxis.line.color="white";       var xValueAxis = ChartSpace2.Charts(0).Axes(c2.chAxisPositionCategory);
                       xValueAxis.font.bold=true;
                       xValueAxis.font.size=10;
                       
                       xValueAxis.font.color="white";
                       xValueAxis.line.color="white";
应该是在
var xValueAxis = ChartSpace2.Charts(0).Axes(c2.chAxisPositionCategory);
                       xValueAxis.font.bold=true;
                       xValueAxis.font.size=10;
                       
                       xValueAxis.font.color="white";
                       xValueAxis.line.color="white";这段加句话但具体怎么写不清楚，请各位大侠帮忙
