Hi
I have recently produced a Yii2 version of the Open Source Reportico package. This allows you to embed into your Yii2 app tabular reports with groups, charts, expressions etc
I have had to get to grips the Yii2 and its use of composer, so i would appreciate any feedback on any problems you may find.
Please go to the Reportico Yii2 page here, for instructions on installing and getting started.

Also, I have recently released new version 4.2 for Yii 1.1 which is available here:-
