Thanks for getting in touch!
I am sorry to hear that you are having issues with ShinobiCharts for Android. To answer your question, if you are using the provided SimpleDataAdapter class, you do not need to invoke a method such as redrawChart. Adding new data points will automatically notify the series.
Can you please advise:
Which DataAdapter implementation are you using, SimpleDataAdapter, or your own implementation?
Are you running your code on a real device or an emulator? If a real device, what device please?
What Android API level is the device (or emulator) running?
If at all possible could you please provide a snippet of your code where the data is being loaded?
I am assuming from what you say that the initial data renders correctly?
