Bar plot tooltip activation area about rickshaw HOT 5 CLOSED

correction, the tooltip is activated at both left AND right edges, but not between them :o

wow, found the bug.. in Rickshaw.Graph.HoverDetail there is a line saying
if (e.target.nodeName != 'path' && e.target.nodeName != 'svg') return;
however, in bar plots, the bar itself is a rect.. so changing that to
if (e.target.nodeName != 'path' && e.target.nodeName != 'svg' && e.target.nodeName != 'rect') return;
fixes things.

Thank you, I had the same issue the other day.

Actually, I think that e.target.nodeName != 'svg' should be removed from there.. since when you're hovering over the canvas itself, i.e. not one of the bars or areas, you shouldn't be triggering any tooltips (which won't be shown anyway, it just does all the useless processing..)

It gets tricky with scatter plots and lines. Since they're such small targets, it's nice now that you don't have to work too hard to see the tooltips.

Whitelisting rect gets us going for now, but it might be nicer to have renderers register relevant elements directly in the future.
