【问题描述】：
您好，我正在尝试使用 mschart 控件在一个表单上表示两个图形（饼图和条形图）......数据来自数据库......
我正在使用单个图表（kpichart）控件来表示两个图形....
为此，我在代码下面写了
在这段代码中，我定义了两个不同的区域来定义两个图形.....
public void KpiMembers_MouseClick(object sender, MouseEventArgs e)

我的问题是我试图显示两个不同的图表（一个是饼图，另一个是堆积柱形图）....
但它显示了两个相同的图表（都是饼图），请参见下图
我想在第二个中显示堆积柱形图而不是饼图....但它显示了两个相同的图表（饼图）
我将整个表格分为两个区域.....
如何使用单个图表控件在同一表单上显示两个不同的图表
有没有人帮忙解决这个问题....
非常感谢您的任何想法.....
