I had an oldish web application I was using jquery 1.7.1 and sparklines 2.1.2 and everything was working AMAZING once I got used to it
Then today I decided to upgrade my jQuery to 3.2.0 and worked out the rest of the bugs between versions and now my sparkline doesn't work.
In Chrome I asked the debugger to stop on all exceptions and it produced this result for me
DOMException: Failed to execute 'querySelectorAll' on 'Element':'*,:x' is not a valid selector
Any ideas? I've attached the sparkline js file I'm using on my server
Thanks for any help you can provide!
