我想“一诊”、“二诊”各生成一个图表，如何修改增加第二个图系的代码？请指教。谢谢！

2个图表使用2个ChartBuilder 分别处理
Dim Chart As New ChartBuilder
第一个图表的代码
Dim Chart2 As New ChartBuilder
第二个图表的代码

添加图片也要添加2次啊
s(t.rows.Count + 2,1).Value = New XLS.Picture(Chart.Image)
s(t.rows.Count + 20,1).Value = New XLS.Picture(Chart2.Image)

第二个图表只有2017级的条形图并且增加了18行空表格线。

仔细对比第一个图表代码，看哪里用错了。
空白格的问题下面20改为合适的值测试
s(t.rows.Count + 20,1).Value = New XLS.Picture(Chart2.Image)

调整s(t.rows.Count + 20,1).Value = New XLS.Picture(Chart2.Image)中“20”的值始终有空白格。如果仍为“2”，则与第一个图表重合。只有不加网格线才能解决此问题。
但第二个图表的纵坐标标识在右边，能否显示在左边，如何修改代码？请指教。谢谢!

1、设置完样式，再添加第2个图表
2、第2个图表也是使用SeriesList，不是使用SeriesList2
Chart2.SeriesList.Add

把边框的设置也加到红色代码里
