@aapril98,
You can create DIV containers corresponding to each dataPoint as shown below –
<div id="DevJan" style="height: 17px; width: 100%;"> Delivered </div>
<div id="NotDevJan" style="height: 17px; width: 100%;"> Not Delivered</div>
Then, hide/unhide the specific DIV container using jQuery as shown in the below code snippet – 
click: function (e){
  if( e.dataPoint.dataPoints === "Delivered"){
    $("#DevJan").show();
    $("#NotDevJan").hide();
  }else{
    $("#DevJan").hide();
    $("#NotDevJan").show();
  }
},
Please take a look at this JSFiddle for a working example.
