使用morris.js从条形图中删除悬停图例

Question

我正在使用morris.js library来生成图表。

我想从图表中删除悬停图例。请检查下面的图片以获得更好的理解。如何删除它们？有解决的办法吗？预先感谢。

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（布尔值）-始终显示悬停图例
• true（布尔值）或'auto'（字符串）-仅当鼠标光标位于图表上方时才显示悬停图例
• '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'
});

您还可以通过为callback属性分配hoverCallback函数来自定义悬停图例：

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;
  }
});
