Hello,
https://jsfiddle.net/7Ln2rf8h/4/
In my chart I want to display two lines. One line does not change, for the other line the user has the possibility to select the data he/she is interested in. The selection runs over a simple dropdown menu.
The problem I have is that updating the data after the selection doesn't quite work and I don't see the reason for that.
If you go to "Satisfaction" the data changes as desired, but if you go back nothing happens.
Thanks
