How to send two arrays simultaneously to view using JSON asp.net MVC

I have to create a dynamic chart in my view based off a value a user would enter into an input contained in a beginform in my view, however it has to be done asynchronously thus why I am using Ajax and Json, I send the user input to the controller fine and then using that input my code creates two Arrays one string array that would be used as my labels for my chart and the other an int array that is used as the data values for the chart.
