I am trying to add annotation to a chart with horizontal DateTimeCategoricalAxis by using this code, but it keeps crashing
I have tried making PenaltyValue a string, a Calendar, and a Date. It always crashes and logcat reports this error
java.lang.IllegalArgumentException: the value: Mon Feb 01 12:48:15 EST 2016 proved to be incompatible with its corresponding axis
How do I fix it.
