JS Google图表无法更改饼图背景颜色

Question

I tried this code, but my pie bg color is still blue.. could you advise something?

  var options = {

  chart: {
  backgroundColor: 'brown', // for the area outside the chartArea
  chartArea: {
  backgroundColor: 'green'
}
  }

};

Answer 1

chartArea is not a valid key... Just use backgroundColor .

var options = {
    backgroundColor: 'brown',
    chartArea: {
        backgroundColor: 'green'
    }
}
