Dynamic diagram

Hello everyone,

Attached you will find an example worksheet of my problems:

I would like to have a diagram which shows, depending on which of the two ActiveX-Options I press, either Data 1 or Data 2.
The problem is that the title of the axes and the overall title ("This is data 1"&cell-link) need to switch as well.

I would be really really glad if you could help me.

Thanks a lot in advance!Test1.xlsx
