Accepted answer

You actually want two series: data parameters (one for each column).

The first column will be the accept data and the second column will be your fail data since I am guessing that your category label which in the example image is Apples will be a Branch of Studies.

Your series should look something similar to the following:

series: [{
      name: "Accept",
      data: accept,
      name: "Fail",
      data: fail,

Your accept and fail arrays are currently arrays of arrays, but they can actually be a simple list as seen in the Highcharts demo here. You can then specify in the xAxis parameter the categories: that are your Branch of Studies.
