Breaking: Chart.js > 2.2.0 doesn't support Bower

[madeleineostoja]

Chart.js dropped support for Bower in 2.2.0 and no longer includes compiled files, which breaks everything (and on a minor version at that).

They recommend using bower-npm-resolver to install via Bower, though that would mean forcing an NPM dep for users of chart-elements.

Alternatively could install Chart.js with NPM and inline the script in a buildstep, using something like gulp-inline-source.

The best solution that comes to my mind is to remove Chart.js from bower dependencies. Remove chart-js-import.html and make it clear in the README.md that Chart.js needs to be installed and loaded manually. Probably the safest and most flexible way. What do you think @robdodson ?

[robdodson]

@pkaske Hm... yeah I guess we can go with that approach. The Polymer team is working on npm support, I'll go bug them some more

[madeleineostoja]

In the meantime worth freezing the Chart.js bower dep at 2.1.x

[trading-peter]

I've frozen the dependency at version 2.1.6. That's the last one with included build files. Only a tmp fix but at least people can in the meantime expect that chart-elements works as expected.

Hello, is there a stacked option in this wrapper for the bar-chart please? if yes, is there a way for you to give me an example it wound be very appreciated! Sorry if this isn't the place to ask such questions :p

[trading-peter]

@mahasaez I've never used it but Chart.js has a stacked option. You can set options for your charts with the options property of the element. https://robdodson.github.io/chart-elements/components/chart-elements/#chart-bar:property-options

If you have more questions on how to configure your chart, your best bet is http://www.chartjs.org/docs/#bar-chart-chart-options

If you have more questions on chart-elements itself, please open a new issue.

I don't know how, but version 2.3.0 seems to come with dist folder again

$ ls app/bower_components/chart.js/dist/
ls: cannot access app/bower_components/chart.js/dist/: No such file or directory

$ bower install --save chart.js
bower chart.js#*            not-cached https://github.com/chartjs/Chart.js.git#*
bower chart.js#*               resolve https://github.com/chartjs/Chart.js.git#*
bower chart.js#*              checkout v2.3.0
bower chart.js#*              resolved https://github.com/chartjs/Chart.js.git#2.3.0
bower chart.js#^2.3.0          install chart.js#2.3.0

$ ls app/bower_components/chart.js/dist/
Chart.bundle.js  Chart.bundle.min.js  Chart.js  Chart.min.js

Why I don't know? I don't see a bower.json file in that repository. But there seem some automatic building. But how does it work, so I understand...

Edit: Aaah, there are specific release commits and i'ts build for it (eg. see https://github.com/chartjs/Chart.js/tree/v2.3.0)

[trading-peter]

Yeah, they re-added the dist folder. I will soon update the dependencies.
