# Morris.js - pretty time-series line graphs [](http://travis-ci.org/morrisjs/morris.js) Morris.js is the library that powers the graphs on http://howmanyleft.co.uk/. It's a very simple API for drawing line, bar, area and donut charts. Cheers! \- Olly (olly@oesmith.co.uk) ## Contributors wanted I'm unfortunately not able to actively support Morris.js any more. I keep an eye on the issues, but I rarely have the time to fix bugs or review pull requests. If you're interested in actively contributing to Morris.js, please contact me on the email address above. ## Requirements - [jQuery](http://jquery.com/) (>= 1.7 recommended, but it'll probably work with older versions) - [Raphael.js](http://raphaeljs.com/) (>= 2.0) ## Usage See [the website](http://morrisjs.github.com/morris.js/). ## Development Very daring. Fork, hack, possibly even add some tests, then send a pull request :) Remember that Morris.js is a coffeescript project. Please make your changes in the `.coffee` files, not in the compiled javascript files in the root directory of the project. ### Developer quick-start You'll need [node.js](https://nodejs.org). I recommend using [nvm](https://github.com/creationix/nvm) for installing node in development environments. With node installed, install [grunt](https://github.com/cowboy/grunt) using `npm install -g grunt-cli`, and then the rest of the test/build dependencies with `npm install` in the morris.js project folder. Once you're all set up, you can compile, minify and run the tests using `grunt`. Note: I'm experimenting with using perceptual diffs to catch rendering regressions. Due to font rendering differences between platforms, the pdiff tests currently *only* pass on OS X. ## Changelog ### 0.5.1 - 15th June 2014 - Fix touch event handling. - Fix stacked=false in bar chart [#275](https://github.com/morrisjs/morris.js/issues/275) - Configurable vertical segments [#297](https://github.com/morrisjs/morris.js/issues/297) - Deprecate continuousLine option. ### 0.5.0 - 19th March 2014 - Update grunt dependency [#288](https://github.com/morrisjs/morris.js/issues/228) - Donut segment color config in data objects [#281](https://github.com/morrisjs/morris.js/issues/281) - Customisable line widths and point drawing [#272](https://github.com/morrisjs/morris.js/issues/272) - Bugfix for @options.smooth [#266](https://github.com/morrisjs/morris.js/issues/266) - Option to disable axes individually [#253](https://github.com/morrisjs/morris.js/issues/253) - Range selection [#252](https://github.com/morrisjs/morris.js/issues/252) - Week format for x-labels [#250](https://github.com/morrisjs/morris.js/issues/250) - Update developer quickstart instructions [#243](https://github.com/morrisjs/morris.js/issues/243) - Experimenting with perceptual diffs. - Add original data row to hover callback [#264](https://github.com/morrisjs/morris.js/issues/264) - setData method for donut charts [#211](https://github.com/morrisjs/morris.js/issues/211) - Automatic resizing [#111](https://github.com/morrisjs/morris.js/issues/111) - Fix travis builds [#298](https://github.com/morrisjs/morris.js/issues/298) - Option for rounded corners on bar charts [#305](https://github.com/morrisjs/morris.js/issues/305) - Option to set padding for X axis labels [#306](https://github.com/morrisjs/morris.js/issues/306) - Use local javascript for examples. - Events on non-time series [#314](https://github.com/morrisjs/morris.js/issues/314) ### 0.4.3 - 12th May 2013 - Fix flickering hover box [#186](https://github.com/morrisjs/morris.js/issues/186) - xLabelAngle option (diagonal labels!!)
