Generate grids in Javascript API

SteveLi — Mon, 13 Sep 2010 20:37:15 GMT

I have a challenge to dynamically generate several thousands shaded grids as graphics in javascript api. It just too slow.

I saw a sample in Flex use BitmapData.fillRect,which can render grids really fast. Is there a similar thing in JS?

Thanks.

Thousands of features is pushing beyond the limits of JS API graphics and into map service territory. But I know you said this needs to be dynamic so...do you need to have thousands of graphics visible at one time?

Can you post what you've got right now? And a link to the flex sample you're talking about?
