javascript - 使用 morris.js 从条形图中删除悬停图例

Question

我正在使用 morris.js library生成图表。

我想从图表中删除悬停图例。请查看下图以便更好地理解。我怎样才能删除它们？有什么办法解决吗？提前致谢。

new Morris.Bar({
  // ID of the element in which to draw the chart.
  element: 'myfirstchart',
  // Chart data records -- each entry in this array corresponds to a point on
  // the chart.
  data: [
    {year: '2008', value: 20},
    {year: '2009', value: 10},
    {year: '2010', value: 5},
    {year: '2011', value: 5},
    {year: '2012', value: 20}
  ],
  // The name of the data record attribute that contains x-values.
  xkey: 'year',
  // A list of names of data record attributes that contain y-values.
  ykeys: ['value'],
  // Labels for the ykeys -- will be displayed when you hover over the
  // chart.
  labels: ['Value']
});

要禁用悬停图例，请使用 hideHover 属性并将其设置为 'always'。

hideHover 属性接受以下值:

• false( bool 值)- 始终显示悬停图例
• true( bool 值)或 'auto'(字符串)- 当鼠标光标悬停在图表上时，仅显示悬停图例
• 'always'(字符串)- 从不显示悬停图例

new Morris.Bar({
  // ID of the element in which to draw the chart.
  element: 'myfirstchart',
  // Chart data records -- each entry in this array corresponds to a point on
  // the chart.
  data: [
    {year: '2008', value: 20},
    {year: '2009', value: 10},
    {year: '2010', value: 5},
    {year: '2011', value: 5},
    {year: '2012', value: 20}
  ],
  // The name of the data record attribute that contains x-values.
  xkey: 'year',
  // A list of names of data record attributes that contain y-values.
  ykeys: ['value'],
  // Labels for the ykeys -- will be displayed when you hover over the
  // chart.
  labels: ['Value'],
  // Remove hover legend
  hideHover: 'always'
});

您还可以通过将 callback 函数分配给 hoverCallback 属性来自定义悬停图例:

new Morris.Bar({
  // ID of the element in which to draw the chart.
  element: 'myfirstchart',
  // Chart data records -- each entry in this array corresponds to a point on
  // the chart.
  data: [
    {year: '2008', value: 20},
    {year: '2009', value: 10},
    {year: '2010', value: 5},
    {year: '2011', value: 5},
    {year: '2012', value: 20}
  ],
  // The name of the data record attribute that contains x-values.
  xkey: 'year',
  // A list of names of data record attributes that contain y-values.
  ykeys: ['value'],
  // Labels for the ykeys -- will be displayed when you hover over the
  // chart.
  labels: ['Value'],
  // Customized hover legend via a callback
  hoverCallback: function (index, options, content, row) {
    return 'Legend ' + index + '<br> on year ' + row.year + '<br> with value ' + row.value;
  }
});
