java.lang.NegativeArraySizeException

[leijdekkers]

Hi

I upgraded from MPAndroid v2.1.0 to v2.1.6 and i get now this runtime error in a combined chart consisting of LineData and CandleData. Any idea what goes wrong? Was working before in V2.1.0

Thanks Peter

Ok i solved it by forcing both sets to have exactly the same number of items in their dataset. I think there is a bug in the Candle class since i tested it with the Bar set using different dataset sizes and no problem. Maybe something to check?
