# v2.2.1 (2023-02-16) ## Future incompatibilities - `window.smoothPlotter` will not be set by `extras/smooth-plotter.js` any more RSN ## New features - Permit initialising with `[]` as “no data yet” indicator (#597) - The modularisation of the test setup also allows stable access to exported functions (e.g. `Dygraph._require('dygraphs/src/dygraph-utils.js').numberValueFormatter`) which makes writing one’s own value formatters easier (as usual, proceed with care, exports with an underscore are internal); see <https://dygraphs.com/tests/exported-symbols.html> for the exposed surface - Provide Dygraph.onDOMready(cb) as lightweight jQuery(cb)/… alternative, to keep the demos/tests self-contained ## Bugfixes - Fix synchroniser not calling user’s `drawCallback` when blocked (#953) plus do not redraw unnecessarily - Documentation fixes and improvements including self-checks where possible - Fix missing legend for `x == -1` (#1002) - Allow ES6-importing the extras (#848) (#989) (#1009) - Fix broken zoom also in the drawing test (same as #611/#953) - Resetting `panEdgeFraction` now works - Fix tests/unboxed-spark regression caused by PR #936 - Synchroniser doesn’t force x axis range if unzoomed (#956) ## Other user-visible changes - Fix issue #611 in the drawing demo gallery (#953) - `jq` is now also required to build - Fix typos, wordings, apostrophes, etc. - Export `pickDateTickGranularity` so overriding `dateTicker` is easier - Error bars are now properly called high/low bands (#1004), but the options stay the same for compatibility - Document annotations xval for Date better (#970) - Document more strongly that series labels must be unique (#960) - Remove references to nōn-existing `yAxisLabelWidth` option - Fix jsFiddle links from gallery ## Internal refactors/fixes - Shrink `tests.js` source map and make its build reproducible on Debian - `tests/resizable.html` exposes the graph object, for quick F12 in-browser use - Generate `versions.html` and release notes from new top-level [`CHANGES.md`](https://github.com/danvk/dygraphs/blob/master/CHANGES.md) - Modularise dygraphs/tests setup so we can now also test the minified prod css/js (#1028) - Generate stable orig tarballs for releases ourselves (we still use the NPM ones for binary tarballs) - Less fragility with arrow function `this` rebinding check # v2.2.0 (2023-01-25) This is the first “full” release after v2.1.0 with the following news: ## Breaking changes - Stop parsing the deprecated 8-digit ‘YYYYMMDD’ date format (#984) (#985) (#1023) - GWT “support” is no longer pertinent as we cannot recompile the binary JAR; the latter is still available from the website for now ## New features - Add option to colour the range selector’s veil (#856) - Add `strokeStyle` option to crosshair plugin (#955) - Support `DocumentFragment` as a result from a `legendFormatter` function (#958) (#959) - Add data index to `legendFormatter` data (#965) - Implement `#RRGGBB`/`#RRGGBBAA` hex colour parsing - Make `animateBackgroundFade` into an option - Add new `resizable` option using `ResizeObserver` on maindiv + CSS - Add offset config for legend div in follow mode (#946) ## Bugfixes - Fix duplicate annotation when having duplicate points (#826) - Make sure that `canvasx` and `canvasy` properties are initialised from the start (#896) - Fix issue #781 when the y range is zero (#909) - Synchroniser now calls `highlightCallback` (#935) - Fix `drawAxes` to allow one of two y axes to be drawn (#936) - LEGEND: Don’t show y if value is undefined (#853) (#947) - Fixed “Cannot read property 'length' of undefined” issue (#962) (#963) - Two fixes in the calculations of pinch-zoom (#990) - Fix for double paint of grid of x-axis (#1007) - Fix number of days in a year (#1012) - Fix `labelsKMB` and `labelsKMG2` (#571) (#994) (#1022) - Fix label position in `onmouseover` legend mode was never updated - Fix several cases of mispositioning/missizing by enabling elements before using `offsetWidth` etc. - Make it possible to use `logscale` (and `sigma`, `wilsonInterval`) per-axis (#986) ## Other user-visible changes - Documentation is now shipped (mostly self-contained) in the release - Tests that use Google JSAPI are now marked ⚠ and no other external content is loaded anywhere - Calculate legend positioning relative to closest data point (#1013) - Add missing documentation about annotations `xval` option (#992) - source mapping URLs are now correct (#1027) - Ship ES5 versions of extras (#952), use them in examples - Fix documentation/website HTML/CSS/JS bugs (#979) (#1008) - On the website, external links are now clearly labelled - The documentation and website now have browsable subdirectories by manually generated directory index files - Link to UNPKG as CDN as well (to keep neutral;
