For ‘RenderViewComparative’ if I change one representation, then all other representations change synchronously.  
[render\_view\_comparative.avi](https://discourse.paraview.org/uploads/default/original/2X/0/0bc3c4ec1f09d725c885f8e49bcc2b1976c17f86.avi) (1.3 MB)

For ‘LineChartViewComparative’ if I change the first representation, then i need to hover the mouse over the representation and if I change not the first representation, then other representations will not be updated  
[linechart\_view\_comparative.avi](https://discourse.paraview.org/uploads/default/original/2X/b/b38ded1018903722bbba3d430da0c0fc2f4ba54b.avi) (2.6 MB)

Is it a bug or a feature? Сan I make the line chart views update immediately, like the render views?
