How do you run Google Charts locally?

Question

I am looking at using Google Charts to have scatter plot. All of the examples have external dependency, and I would like to avoid that as this is an intranet application that doesn't have external Internet access.

<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
 <script type="text/javascript">
   google.charts.load('current', {packages: ['corechart']});
   google.charts.setOnLoadCallback(drawChart);
...
</script>

Can I simply just copy loader.js locally or is there something more complicated that I need to worry about here? The reason I ask is that I tried doing that and it's not working so I am trying to figure out if what I am doing is fundamentally flawed or I might have an unrelated issue.

Answer 1

No. It is not allowed per the Google agreements https://developers.google.com/chart/interactive/faq

Off line use is not allowed.

Answer 2

You should be able to run charts/loader.js locally and have it work just fine. I just copied and pasted its contents into a new js file and my charts rendered as normal.

The source code is too large for me to use as a snippet in the answer, but here's a working fiddle that uses the pasted code from charts/loader.js to create a table: https://jsfiddle.net/q078fvw1/

If you right click on the file in your header that reads

<script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>

This ought to work.

If not, then it's probably something on your system that's causing the interference.

Edit: While my answer might be literally correct vis a vis being able to use the source code locally, I wasn't making any recommendations with regards to whether or not this is the best thing to do.

As another poster pointed out, if it's in their service agreement not to use it locally then it's wise to comply with their terms.
