The excanvas emulation used for IE (built with +VML) makes IE by far the slowest browser so be sure to test with that +if IE users are in your target group. + +1000 points is not a problem, but as soon as you start having more +points than the pixel width, you should probably start thinking about +downsampling/aggregation as this is near the resolution limit of the +chart anyway. If you downsample server-side, you also save bandwidth. + + Q: Flot isn't working when I'm using JSON data as source! A: Actually, Flot loves JSON data, you just got the format wrong.
