Remove 200x200 minimum size from chart

There was no reason for enforcing the 200x200 minimum size for the
chart, as the minimum size already took into account various chart
element minimum sizes. Legend and chart title also no longer
contribute to the minimum size if they are not visible.

Some autotests that simulated mouse events were relying on this
minimum size, so added explicit resizes to some of them.
