Example syncronized Zooming

[guylian stevens]

Dear all, 

I'm trying to use the syncronized zooming example. 

https://support.syncfusion.com/kb/article/9939/how-to-synchronize-panning-in-multiple-charts-sfcartesianchart

However when I'm trying to implement it, I always get the following error: 

Undefined class 'CategoryAxisController'.
Try changing the name to the name of an existing class, or creating a class with the name 'CategoryAxisController'.

It seems like I cannot acces any of the classes defined in syncfusion_flutter_charts/charts.dart

I'm using version 20.4.54.

Kind regards, 

Guylian
