Make all legend entries visible and readable

[jashwood1]

legend entries truncate and sometimes do not show. The height of a dashboard item needs to be dynamic to allow full legend text to be visible and all entries should show when there is a small number (e.g. 5)

It would be great to have the option to wrap the legend so that it shows all items by taking up more chart space where necessary.
