如何更改Google饼图中的文本“无数据" [英] how to change the text 'no data' in google pie chart

问题描述

如果我为图表绑定传递空数据，则显示无数据"，我需要将文本无数据"更改为其他字词.

if i am passing empty data for chart binding it shows 'no data' i need to change the text 'no data' to some other word.

  google.load("visualization", "1", {packages:["corechart"]});
  google.setOnLoadCallback(drawChart);
  function drawChart() {
    var data = google.visualization.arrayToDataTable([
      ['Task', 'Hours per Day']

    ]);

    var options = {
      title: 'My Daily Activities'
    };

    var chart = new google.visualization.PieChart(document.getElementById('piechart'));
    chart.draw(data, options);
  }

推荐答案

您可以手动进行:

if(data.getNumberOfRows() == 0){
    $("#piechart").append("Sorry, not info available")
}else{
    var chart = new google.visualization.PieChart(document.getElementById('piechart'));
    chart.draw(data, options);        
}
