@jbent90914,
There was an issue in setting minimum & maximum of slider programmatically using set method after changing the range manually. We have just released StockChart v1.0.7 with this bug fix. Please refer to the release blog for more information. Do download the latest version from download page & let us know your feedback.
If you are still facing issue, kindly create JSFiddle reproducing the issue you are facing with sample / dummy data and share it with us so that we can look into your code / StockChart options being used, understand the scenario better and help you out.
