Question

当您将鼠标悬停在图表上时，我需要格式化我的饼图和柱形图以显示货币格式的$和逗号（$ ###，###）。现在，它显示数字和百分比，但数字为#####。##这里是我的代码。任何帮助将不胜感激。

// Load the Visualization API and the piechart package.
      google.load('visualization', '1.0', {'packages':['corechart']});

      // Set a callback to run when the Google Visualization API is loaded.
      google.setOnLoadCallback(drawChart);

      var formatter = new google.visualization.NumberFormat({
            prefix: '$'
        });
        formatter.format(data, 1);

        var options = {
            pieSliceText: 'value'
        };

      // Callback that creates and populates a data table,
      // instantiates the pie chart, passes in the data and
      // draws it.
     function drawChart() {

Answer 1

您需要更改：

   var formatter = new google.visualization.NumberFormat(
      {negativeColor: 'red', negativeParens: true, pattern: '$###,###'});
   formatter.format(data, 1);

而不是：

  var formatter = new google.visualization.NumberFormat({
        prefix: '$'
    });
