我建议您将所有“drawcharts”函数从一个回调调用到google.setOnLoadCallback

这是一个有效的jsfiddle。 https://jsfiddle.net/oakley808/z5j9u2sw/

google.load("visualization", "1", {
  packages: ["corechart", "bar"]
});
google.setOnLoadCallback(function(){
    drawcharts()
    drawcharts1()
    drawChart()
    drawChart3()
})

function drawcharts() {

  var data1 = google.visualization.arrayToDataTable(
    [
      ['Year', 'Derby', 'Bristol', 'Warrington', 'Indianapolis', 'Dahlewitz', 'Montreal'],
      ['2012', 143754.00, 7607.59, 958.51, 6029.12, 13605.12, 586.00],
      ['2013', 186065.32, 1674.50, 1823.93, 9574.24, 23935.14, 743.43],
      ['2014', 251238.53, 0, 0, 10154.41, 19926.63, 363.71],

无法在单个网页上加载所有谷歌图表。我错过了什么？
