You should be able to do this without Javascript.
You can get data from the chart and pass it into your url parameter using merge syntax. Add actions under each series to configure what you want to have happen when the chart element is selected.
For example if you define a url like this “apex/accountDetail?Id={{rows.0.Id}}” the Id field from the first row in the chart element (say column) will be passed into the url.
This post has some good conversation about the data that can be extracted from charts and passed into your actions… https://community.skuid.com/t/chart
