Hi mahdyswessi,

Sorry for the confusion. We gave these steps for users to use the latest version of Dev Express charts:

Here is the video that shows how to setup DevExpress charts in our theme:

Please note that the only reason why we don't include the Charts library in our theme is because they do not provide such a license.

So basically here is what you need to do:

1. Install DevExpress Charts via Bower:

bower install devextreme#~18.1 --save

2. Then copy only the:

.../bower_components/devextreme/js/dx.all.js

In your assets folder, lets say:

.../assets/js/devextreme/dx.all.js

3. Then in your document file apply it:

<script src="assets/js/devextreme/dx.all.js"></script>

I tested and it worked.
