Have a grid view (e.g. 3 plots per line instead of just one)Yes the plots are resizable move the cursor to the separating line and drag 🙂
2. Check the group by section, they can be split per series (like in TB)

Hover near the edge of the plot, the you should get a "bar" you can click on to resize

In the version we have I don't see that the plots are resizable - we are running 1.1.0, I believe
