Need help installing chart package


I’m having trouble installing some chart package. Either one is fine
or you can suggest one.

So it works when simply adding this lines
<script src=“”></script>
<script src=“”></script>

but when

npm install xxx --save

I just cannot succed. (I previously installed jQuery and other packages with succes).

I played with the vendor folder but I’m, just not that qualified to work it out.

So the question is, how can I install chartjs or highcharts?

Thanks for help.

import “chart.js” should work without problem. What kind of error you get in browser console ?

You might also specify if You use brunch or webpack, or any other tool :slight_smile:

I use brunch.

reports:119 Uncaught ReferenceError: Chart is not defined

import “chart.js” won’t work.

your chart codes in app.js or in page with script tag ?

Can you look if chart.js imported in app.js, localhost:4000/js/app.js
