Plotting the Events done

Browse source 
There are subtle differences, the Cairo version looks
prettier - but that's fixable. I did a small triangle
and a exclamation mark on it. maybe a gradient would
make a good difference there.

this item has a ItemIgnoresTransformation tag, so
scalling, rotating or zooming will not change it's
size.

The tooltips are not yet ported.
