I think there is a potential to greatly improve the rendering performance in
IE (cases of large# of points).
Take points for example. In VML.js setStyle, every .style action seems to
trigger a browser reflow:
node.style.width=18px; //1st reflow
node.style.height=18px; //2nd reflow
Hi,
setting cssText is not the same as setting the style. But you could instead try
to call
node.style.display = none;
as first line of the setStyle method, and
node.style.display = ;
as last line of the setStyle method.
Let us know if this also boosts performance.
Good luck,
Andreas.
