As for putting different charts in a single panel, yes it is possible by using the same panel but different groups (for instance layoutPanel="panel_row2_col1_grp1", layoutPanel="panel_row2_col1_grp2" and so on).
I hope i am clear here so here goes:
I have the below panel, and what I want to do is add a tab so that I can 2 tabs, in total, and I can switch between, tab1 and tab2. The below panel is a chart but for example I would want tab2 to be a table for the same search. Can you advise based on your comment above?
