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. -Double check that you're not inputting strings instead of numbers, -like [["0", "-2.13"], ["5", "4.3"]]. This is most common mistake, and -the error might not show up immediately because Javascript can do some -conversion automatically. - - -Q: Can I export the graph? - -A: This is a limitation of the canvas technology. There's a hook in -the canvas object for getting an image out, but you won't get the tick -labels. And it's not likely to be supported by IE. At this point, your -best bet is probably taking a screenshot, e.g. with PrtScn. - - -Q: The bars are all tiny in time mode? - -A: It's not really possible to determine the bar width automatically. -So you have to set the width with the barWidth option which is NOT in -pixels, but in the units of the x axis (or the y axis for horizontal -bars). For time mode that's milliseconds so the default value of 1 -makes the bars 1 millisecond wide. - - -Q: Can I use Flot with libraries like Mootools or Prototype? - -A: Yes, Flot supports it out of the box and it's easy! Just use jQuery -instead of $, e.g. call jQuery.plot instead of $.plot and use -jQuery(something) instead of $(something). As a convenience, you can -put in a DOM element for the graph placeholder where the examples and -the API documentation are using jQuery objects. - -Depending on how you include jQuery, you may have to add one line of -code to prevent jQuery from overwriting functions from the other -libraries, see the documentation in jQuery ("Using jQuery with other -libraries") for details. - - -Q: Flot doesn't work with [insert name of Javascript UI framework]! - -A: The only non-standard thing used by Flot is the canvas tag; -otherwise it is simply a series of absolute positioned divs within the -placeholder tag you put in. If this is not working, it's probably -because the framework you're using is doing something weird with the -DOM, or you're using it the wrong way. - -A common problem is that there's display:none on a container until the -user does something. Many tab widgets work this way, and there's -nothing wrong with it - you just can't call Flot inside a display:none -container as explained in the README so you need to hold off the Flot -call until the container is actually displayed (or use -visibility:hidden instead of display:none or move the container -off-screen). - -If you find there's a specific thing we can do to Flot to help, feel -free to submit a bug report. Otherwise, you're welcome to ask for help -on the forum/mailing list, but please don't submit a bug report to -Flot. |
