Thanks for the response. But managed to figure it out. I need to make changes to my Ajax call to update the values of my doughnuts directly and get rid of my table_space function:

 $.ajax({
        url: "<!--#include virtual="../include/env"-->/data",
        type: "GET",
        cache: "false",
        success: function(value) {
        Doughnut1.data.datasets[0].data = [value[0].USED, value[0].FREE]
        Doughnut2.data.datasets[0].data = [value[1].USED, value[1].FREE]
        Doughnut3.data.datasets[0].data = [value[2].USED, value[2].FREE]
        Doughnut1.update();
        Doughnut2.update();
        Doughnut3.update();
      },
        dataType: "json"
      });
