Hello Yuvaraj,


Thank you for replying.

The issue has solved for my problem. When there are 2 or more data in 'ruangan2', the datetimecategory axis not throw any exception anymore. Still, i don't know why, when in 'ruangan2' only has one data, the datetimecategoryaxis is throw exception about formatException. I checked the file that contain method 'DateTimeCategoryAxis.getFormattedLabel, the error occured in the int.parse(label) inside the method. please consider to check this method. 


thank you,


Syaifullah
