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
