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.
