Change your generalChartData from this:

更改您的generalChartData:

var generalChartData = [
      {"A": "0.08167"},
      {"B": "0.01492"},
      {"C": "0.02782"},
      {"D": "0.04253"},
      {"E": "0.12702"},
      {"F": "0.02288"},
      {"G": "0.02015"},
      {"H": "0.06094"},
      {"I": "0.06966"},
      {"J": "0.00153"}
  ];

To this:

:

 var generalChartData = [
      {letter: "A", frequency: 0.08167},
      {letter: "B", frequency: 0.01492},
      {letter: "C", frequency: 0.02782},
      ...
      {letter: "J", frequency: 0.00153}
  ];
