将数据绑定到 mschart，这样我就可以 return 非数据点值
bounding data to mschart so i can return non-data point-values
我正在尝试构建一个由高达 100% 的堆叠柱组成的图表，每个柱有 4 个系列，一旦构建，将鼠标悬停在系列上时，return 所有绑定数据（在此案例，用户名）
我非常接近我想要的，但工具提示只显示总和，这是预期的，但我不知道如何继续。如果有另一种方式可以越过悬停，比如点击，在点击中，我认出了这个系列和所有那些，那也会有很大的帮助

如果我没理解错的话，您是在尝试显示一个工具提示（当将光标悬停在图表中一种颜色 'block' 上时），它会显示构成该点的数据的相关信息。
问题是每个 'block' 只是一个 X 和 Y 值。例如：显示 'Pessoas = 392' 的工具提示后面的数据点实际上只是一个简单的数据点 (Series-S X=5 Y=392)，没有其他信息。
要以您希望的方式显示工具提示，每个工具提示都必须 pre-set，如下所示：
point.ToolTip = "User1 in the series\nUser2 in the series\n..."
我正在尝试构建一个由高达 100% 的堆叠柱组成的图表，每个柱有 4 个系列，一旦构建，将鼠标悬停在系列上时，return 所有绑定数据（在此案例，用户名）
我非常接近我想要的，但工具提示只显示总和，这是预期的，但我不知道如何继续。如果有另一种方式可以越过悬停，比如点击，在点击中，我认出了这个系列和所有那些，那也会有很大的帮助
