</div></div>Wouldn't it be possible to write a sort of flot plugin for your case?<br>
Maybe thats even the easier way, than to program zooming, panning,<br>
tooltips etc. yourself.<br>
Then I could also use flot for my statistics page :D<br>
<div><br></div></blockquote><div><br></div></div></div><div>Nice idea :) </div><div>But that would most probably amount to re-writing flot altogether. The thing is flot is not designed to draw shapes and all. </div><div>
IMO handling zooming, panning and tooltips with SVG is far easier than that :)</div>
