Attractive Javascript plotting for jQuery Flot is a free and open source Javascript plotting library for jQuery, that produces graphical plots of arbitrary datasets on-the-fly client-side. The focus is on simple usage (all settings are optional), attractive looks and interactive features like zooming and mouse tracking. Requirements: · jQuery · Java What's New in This Release: · Backwards API change summary: Timestamps are now in UTC. Also "selected" event -> becomes "plotselected" with new data, the parameters for setSelection are now different (but backwards compatibility hooks are in place), coloredAreas becomes markings with a new interface (but backwards compatibility hooks are in place). · Interactivity: added a new "plothover" event and this and the "plotclick" event now returns the closest data item (based on patch by /david, patch by Mark Byers for bar support). See the revamped "interacting with the data" example for some hints on what you can do. · Highlighting: you can now highlight points and datapoints are autohighlighted when you hover over them (if hovering is turned on). · Support for dual axis has been added (based on patch by someone who's annoyed and /david). For each data series you can specify which axes it belongs to, and there are two more axes, x2axis and y2axis, to customize. This affects the "selected" event which has been renamed to "plotselected" and spews out { xaxis: { from: -10, to: 20 } ... }, setSelection in which the parameters are on a new form (backwards compatible hooks are in place so old code shouldn't break) and markings (formerly coloredAreas). · Timestamps in time mode are now displayed according to UTC instead of the time zone of the visitor. This affects the way the timestamps should be input; you'll probably have to offset the timestamps according to your local time zone. It also affects any custom date handling code (which basically now should use the equivalent UTC date mehods, e.g. .setUTCMonth() instead of .setMonth(). · Added support for specifying the size of tick labels (axis.labelWidth, axis.labelHeight). Useful for specifying a max label size to keep multiple plots aligned. · Markings, previously coloredAreas, are now specified as ranges on the axes, like { xaxis: { from: 0, to: 10 }}. Furthermore with markings you can now draw horizontal/vertical lines by setting from and to to the same coordinate (idea from line support patch by by Ryan Funduk). · The "fill" option can now be a number that specifies the opacity of the fill. · You can now specify a coordinate as null (like ) and Flot will take the other coordinate into account when scaling the axes (based on patch by joebno). · New option for bars "align". Set it to "center" to center the bars on the value they represent. · setSelection now takes a second parameter which you can use to prevent the method from firing the "plotselected" handler. · Using the "container" option in legend now overwrites the container element instead of just appending to it (fixes infinite legend bug, reported by several people, fix by Brad Dewey). · Fixed a bug in calculating spacing around the plot (reported by timothytoe). Fixed a bug in finding max values for all-negative data sets. Prevent the possibility of eternal looping in tick calculations. Fixed a bug when borderWidth is set to 0 (reported by Rob/sanchothefat). Fixed a bug with drawing bars extending below 0 (reported by James Hewitt, patch by Ryan Funduk). Fixed a bug with line widths of bars (reported by MikeM). Fixed a bug with 'nw' and 'sw' legend positions. Improved the handling of axis auto-scaling with bars. Fixed a bug with multi-line x-axis tick labels (reported by Luca Ciano). IE-fix help by Savage Zhang.
