I am glad that your immediate issue is resolved.
I appreciate your feedback regarding a sample app. We do not currently have such an app but you are the first I have encountered with this specific use case. I will make a note of your request and we may consider publishing a blog or similar in the future. I cannot of course guarantee when this may be.
If you were to approach this task however, I still feel that my previous suggested approach would suit, that is by overriding the onDestroy method, and adding additional code to your onCreate method (of your Activity).
In terms of how you actually ‘reset’ your series, you do have several choices. If you are not concerned with animations, you can simply use the removeAll method on the DataAdapter to ‘reset’ the series, then add the data points within the onCreate method.
If, on the other hand you wish the Series perform an entry animation each time it is recreated, you will need to either remove and add the Series as I mentioned, or alternatively, hide and show the Series.
For Series hiding, you would use the following method:
I hope that this helps.
