2.1.0 2017-12-08 | New features: Double click event can be captured and cancelled by plugins setAnnotations's second parameter is now an optional boolean Add `pixelRatio` option, which may allow improved performance on smaller screens by controlling the canvas' pixel ratio X-axis label and tick logic can now operate at millisecond-level granularity Bug fixes: Repair a bug in "Custom interaction modals" demo Internal refactors/fixes: Fix various spelling mistakes Fix a couple of type signatures in dygraph-externs.js
2.0.0 2017-01-11 | Breaking changes: JS files were renamed to dygraph.js and dygraph.min.js. There's now a dygraph.css file that you must include. Dropped support for OldIE and other non-standard browsers. dygraphs works in IE11. I'm not sure about IE9 and IE10. Double-click to unzoom zooms all the way out (and ignores valueRange). Dropped old-style per-axis/per-series options. New features: Add a legendFormatter option `this` is the Dygraph object in all callbacks pass through (row, col) to valueFormatter Option to not sync range in extras/synchronizer.js Additional options for styling the range selector getRowForX method setVisibility can set the visibility of multiple series at once. crosshair plugin extra rebase/straw broom plugin highlightSeriesBackgroundColor option yAxisExtremes() method. Passing strings in native format now throws. (Previously it kinda sorta worked.) Bug fixes: Selections are always cleared with animations synchronizer calls previously-set callbacks synchronizer only syncs when graphs are ready Reset on synchronized graphs failed fix to improve synchronizer performance binary search bug fix in synchronizer Fix range selection when chart is located inside fullscreen element fillAlpha can be set per-series when fillGraph is set. xRangePad was ignored on unzoom Allow selected points where canvas-y coordinate is 0 Using valueRange with Logscale and yRangePad has unexpected results With "drawGapEdgePoints", unwanted point often drawn at beginning of chart Other user-visible changes: “legend: follow” positioning changes Internal refactors: Code moved into a “src/“ directory Tests use Mocha instead of jstd dygraphs is split into ES6 modules and uses some ES6 features (e.g. arrows and destructuring). dygraphs is built using babel & browserify Code coverage is tracked continuously Bundle size is now tracked continuously
1.1.1 2015-06-01 | Set `this` to the dygraph in all callbacks. Minor bug fixes.
1.1.0 2014-12-03 | Highlights include: dygraphs is now "retina" compatible. Dramatically improved performance for filled charts (i.e. fillGraph) More sensible date ticks: "Jan 08"→"Jan 2008", "29Jan"→"29 Jan" Using a non-existent option now throws (w/ dygraph-combined-dev.js) x-axis log scales The `labelsUTC` option forces UTC formatting for all labels. The new DataHandler system allows for more flexibility in data loading. "this" is set to the dygraph in all callbacks. dygraphs has shrunk, because we moved some stuff into "extras" (133kb→122kb) This will be the last major release to support browsers without a native <canvas> implementation. See blog post for more details.
