Annotations with DateTimeCategoricalAxis

[Alex]

I am trying to add annotation to a chart with horizontal DateTimeCategoricalAxis by using this code, but it keeps crashing

1.CartesianCustomAnnotation annotation = new CartesianCustomAnnotation(chartView.getVerticalAxis(), chartView.getHorizontalAxis(), penaltyValue, penaltyMonth, "P");
2.chartView.getAnnotations().add(annotation);

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.

Hi Alexandar,

I answered your question about the same issue in the other thread you posted. In short, the penalty value should be of type double since it corresponds to your vertical axis which ,I assume, is a LinearAxis.
