You push to the labels and data array, if you dont want to show previous data you need to remove this data first or just entirly override the array:

success: function(data) {
  myChartpendapatan.data.labels = [];
  myChartpendapatan.data.datasets[0].data = [];

  $.each(data.result, function(id, value) {
    myChartpendapatan.data.labels.push(value.nama_bidang);
    myChartpendapatan.data.datasets[0].data.push(value.total_anggaran);
  });
  myChartpendapatan.update();
},
