以下代码，如何修改才能达到以下目的： 1.两个指标的示意图在双图表中重叠时，如何透明？
2.如何让双图表导到电子表格更清晰。

Dim Chart As WinForm.Chart '定义一个图表变量
Dim Series As WinForm.ChartSeries '定义一个图系变量
Chart = e.Form.Controls("Chart1") ' 引用窗口中的图表
Chart.VisualEffect = True '加上这一行,让你的图表更漂亮
Chart.ChartType = ChartTypeEnum.Bar '图表1类型该为Bar(条形)
Chart.ChartType2 = ChartTypeEnum.XYPlot '图表2类型该为线形

'Chart.ChartType2 = ChartTypeEnum.BAR
Chart.DataSource = "销售表" '设置绑定表
Chart.SeriesList.Clear() '清除图表原来的图系
Series = Chart.SeriesList.Add() '给图表1增加一个图系
Series.Text = "数量"
Series.X.DataField = "产品" 'X轴绑定到产品列
Series.Y.DataField = "数量" 'Y轴绑定到数量列
Series.DataLabelText = "{#YVAL}"
Chart.SeriesList2.Clear() '清除图表原来的图系
Series = Chart.SeriesList2.Add() '给图表2增加一个图系
Series.Text = "金额"
Series.X.DataField = "产品" 'X轴绑定到产品列
Series.Y.DataField = "金额" 'Y轴绑定到数量列

Chart.AxisY.Text = "数量"
Chart.AxisY2.Text = "金额"
Series.MarkShape= MarkShapeEnum.Diamond
Series.DataLabelText = "{#YVAL}"
