Reply To: 'getTime' of undefined

[aarushi]

Hi
i updated my code and added the libraries and hardcoded the json data.
Please have a look

I am not able to drill down the “daily column charts” again after drilling a new “monthly column chart” from the “yearly pie chart”.
I am getting a ” cannot read property getTime() of undefined ”

Kindly help
