我有一个morris.js条形图。我想把

count

放在这个图表的顶部。我查看了一下，没有找到任何

悬停时，它应显示

值

，但在条形图顶部，它应显示

计数

。有办法吗？类似于给定的图像

这是我的密码

Morris.Bar ({
  element: 'bar-example',
  data: [
    {mapname: 's1', value: 10, count: 3},
    {mapname: 's2', value: 4, count: 4},
    {mapname: 's3', value: 12, count: 13}
  ],
  xkey: 'mapname',
  ykeys: ['value'],
  labels: ['No. of days'],
  barRatio: 0.4,
  xLabelAngle: 35,
  hideHover: 'auto',
  barColors: function (row, series, type) {
    console.log("--> "+row.label, series, type);
    if(row.label == "s1") return "#AD1D28";
    else if(row.label == "s2") return "#DEBB27";
    else if(row.label == "s3") return "#fec04c";
  }
});

您可以在其中进行测试。

尝试将此代码放在CSS中

.morris-hover{position:absolute;z-index:1000;}

    var graphData= [
    {mapname: 's1', value: 10, count: 3},
    {mapname: 's2', value: 4, count: 4},
    {mapname: 's3', value: 12, count: 13}
  ]; //store this to its own var so we can access the counts later


var bar=Morris.Bar ({
  element: 'bar-example',
  data:graphData,
  xkey: 'mapname',
  ykeys: ['value'],
  labels: ['No. of days'],
  barSizeRatio:0.4, //I think you meant barSizeRatio, not barSize
  xLabelAngle: 35,
  hideHover: 'auto',
  barColors: function (row, series, type) {
    //console.log("--> "+row.label, series, type);
    if(row.label == "s1") return "#AD1D28";
    else if(row.label == "s2") return "#DEBB27";
    else if(row.label == "s3") return "#fec04c";
  }
});


//first, find the width of a bar
//this is bar-example width, divided by three, times barSizeRatio
var barWidth=($('#bar-example').width()/3)*(0.4);

//now each thru each bar (rect)

jQuery('rect').each(function (i) {
  var pos=$(this).offset();
  var top=pos.top;
  top-=20; //originate at the top of the bar

  //get the height of the bar
  var barHeight=bar.bars[i];
  top+=barHeight/2; //so we can now stick the number in the vertical-center of the bar as desired
  var left=pos.left;
  //move it over a bit
  left+=barWidth/2; 
  //-size of element...
  left-=10;//should approximately be horizontal center

  $div=jQuery('<div class="count" style="top:'+top+'px;left:'+left+'px;" />'); 
  $div.text(graphData[i].count); //get the count
  jQuery('body').append($div); //stick it into the dom
  console.log($div);
});

.count{
  position:absolute;
  width:10px;
  height:20px;
  line-height:20px;
  color:white;
  font-weight:bold;
  }

.numero{
  text-align: center;
  font-size: 18px !important;
  font-weight: 600 !important;
}

这是一个开始，有点粗糙，但它完成了工作：

.morris-hover{position:absolute;z-index:1000;}

    var graphData= [
    {mapname: 's1', value: 10, count: 3},
    {mapname: 's2', value: 4, count: 4},
    {mapname: 's3', value: 12, count: 13}
  ]; //store this to its own var so we can access the counts later


var bar=Morris.Bar ({
  element: 'bar-example',
  data:graphData,
  xkey: 'mapname',
  ykeys: ['value'],
  labels: ['No. of days'],
  barSizeRatio:0.4, //I think you meant barSizeRatio, not barSize
  xLabelAngle: 35,
  hideHover: 'auto',
  barColors: function (row, series, type) {
    //console.log("--> "+row.label, series, type);
    if(row.label == "s1") return "#AD1D28";
    else if(row.label == "s2") return "#DEBB27";
    else if(row.label == "s3") return "#fec04c";
  }
});


//first, find the width of a bar
//this is bar-example width, divided by three, times barSizeRatio
var barWidth=($('#bar-example').width()/3)*(0.4);

//now each thru each bar (rect)

jQuery('rect').each(function (i) {
  var pos=$(this).offset();
  var top=pos.top;
  top-=20; //originate at the top of the bar

  //get the height of the bar
  var barHeight=bar.bars[i];
  top+=barHeight/2; //so we can now stick the number in the vertical-center of the bar as desired
  var left=pos.left;
  //move it over a bit
  left+=barWidth/2; 
  //-size of element...
  left-=10;//should approximately be horizontal center

  $div=jQuery('<div class="count" style="top:'+top+'px;left:'+left+'px;" />'); 
  $div.text(graphData[i].count); //get the count
  jQuery('body').append($div); //stick it into the dom
  console.log($div);
});

.count{
  position:absolute;
  width:10px;
  height:20px;
  line-height:20px;
  color:white;
  font-weight:bold;
  }

.numero{
  text-align: center;
  font-size: 18px !important;
  font-weight: 600 !important;
}

希望你能用它来创造你想要的效果

我在寻找相同的解决方案时发现了这个问题。这是在javascript/jquery中完成的

我可以和你们分享我正在使用的代码，这些代码是我通过尝试、错误和研究发现的

function parseSVG(s) {
        var div= document.createElementNS('http://www.w3.org/1999/xhtml', 'div');
        div.innerHTML= '<svg xmlns="http://www.w3.org/2000/svg">'+s+'</svg>';
        var frag= document.createDocumentFragment();
        while (div.firstChild.firstChild)
            frag.appendChild(div.firstChild.firstChild);
        return frag;
    }

var theData = [
    {mapname: 's1', value: 10, count: 3},
    {mapname: 's2', value: 4, count: 4},
    {mapname: 's3', value: 12, count: 13}
  ]

Morris.Bar ({
element: 'bar-example',
data: theData,
  xkey: 'mapname',
  ykeys: ['value'],
  labels: ['No. of days'],
  barRatio: 0.4,
  xLabelAngle: 35,
  hideHover: 'auto',
  barColors: function (row, series, type) {
    console.log("--> "+row.label, series, type);
    if(row.label == "s1") return "#AD1D28";
    else if(row.label == "s2") return "#DEBB27";
    else if(row.label == "s3") return "#fec04c";
  }
});

var items = $("#bar-example").find( "svg" ).find("rect");
$.each(items,function(index,v){
    var value = theData[index].count;
    var newY = parseFloat( $(this).attr('y') - 20 );
    var halfWidth = parseFloat( $(this).attr('width') / 2 );
    var newX = parseFloat( $(this).attr('x') ) +  halfWidth;
    var output = '<text style="text-anchor: middle; font: 12px sans-serif;" x="'+newX+'" y="'+newY+'" text-anchor="middle" font="10px &quot;Arial&quot;" stroke="none" fill="#000000" font-size="12px" font-family="sans-serif" font-weight="normal" transform="matrix(1,0,0,1,0,6.875)"><tspan dy="3.75">'+value+'</tspan></text>';
    $("#bar-example").find( "svg" ).append(parseSVG(output));
});

差不多

var halfHeight = parseFloat( $(this).attr('height') / 2 );
var newY = parseFloat( $(this).attr('y') - halfHeight );

这一变化未经测试，但将作为一个良好的起点

问候：）

@chiliNUT@abi1964我放置了多个图表，但我在CSS中遇到了一个问题。数据、酒吧高度等都很好，但是#被堆放在顶部。我已经尝试了CSS中每个位置的迭代。想法或小提琴如何解决这个问题

您可以扩展Morris来实现这一点。请参阅此部分以查看完整的工作片段

添加属性：

Bar.prototype.defaults["labelTop"] = false;

添加原型以绘制标签：

Bar.prototype.drawLabelTop = function(xPos, yPos, text) {
    var label;
    return label = this.raphael.text(xPos, yPos, text)
        .attr('font-size', this.options.gridTextSize)
        .attr('font-family', this.options.gridTextFamily)
        .attr('font-weight', this.options.gridTextWeight)
        .attr('fill', this.options.gridTextColor);
};

修改

Bar.prototype.drawSeries

prototype，添加以下行（在最后一行之前）：

然后在Morris条形图配置中将

labelTop

属性设置为true：

labelTop: true

我发现通过jQuery传递给一个空的p更好

这是最终结果：

这是我的代码：

HTML

<div class="row">
   <div class="col-lg-3 col-md-3 col-sm-6 col-xs-6 ">
      <p class="numero num1"></p>
   </div>
   <div class="col-lg-3 col-md-3 col-sm-6 col-xs-6 ">
      <p class="numero num2"></p>
   </div>
   <div class="col-lg-3 col-md-3 col-sm-6 col-xs-6 ">
      <p class="numero num3"></p>
   </div>
   <div class="col-lg-3 col-md-3 col-sm-6 col-xs-6 ">
      <p class="numero num4"></p>
   </div>
 </div>

CSS

.morris-hover{position:absolute;z-index:1000;}

    var graphData= [
    {mapname: 's1', value: 10, count: 3},
    {mapname: 's2', value: 4, count: 4},
    {mapname: 's3', value: 12, count: 13}
  ]; //store this to its own var so we can access the counts later


var bar=Morris.Bar ({
  element: 'bar-example',
  data:graphData,
  xkey: 'mapname',
  ykeys: ['value'],
  labels: ['No. of days'],
  barSizeRatio:0.4, //I think you meant barSizeRatio, not barSize
  xLabelAngle: 35,
  hideHover: 'auto',
  barColors: function (row, series, type) {
    //console.log("--> "+row.label, series, type);
    if(row.label == "s1") return "#AD1D28";
    else if(row.label == "s2") return "#DEBB27";
    else if(row.label == "s3") return "#fec04c";
  }
});


//first, find the width of a bar
//this is bar-example width, divided by three, times barSizeRatio
var barWidth=($('#bar-example').width()/3)*(0.4);

//now each thru each bar (rect)

jQuery('rect').each(function (i) {
  var pos=$(this).offset();
  var top=pos.top;
  top-=20; //originate at the top of the bar

  //get the height of the bar
  var barHeight=bar.bars[i];
  top+=barHeight/2; //so we can now stick the number in the vertical-center of the bar as desired
  var left=pos.left;
  //move it over a bit
  left+=barWidth/2; 
  //-size of element...
  left-=10;//should approximately be horizontal center

  $div=jQuery('<div class="count" style="top:'+top+'px;left:'+left+'px;" />'); 
  $div.text(graphData[i].count); //get the count
  jQuery('body').append($div); //stick it into the dom
  console.log($div);
});

.count{
  position:absolute;
  width:10px;
  height:20px;
  line-height:20px;
  color:white;
  font-weight:bold;
  }

.numero{
  text-align: center;
  font-size: 18px !important;
  font-weight: 600 !important;
}

我还为每种颜色添加了一个类

希望这对任何人都有帮助：）快乐编码

感谢您的回复，但不仅仅是在悬停状态，而且在所有时间，它都应该在条形图顶部显示

count

。您是否找到解决此问题的方法？我也在想同样的事情。这件事运气好吗？我也有同样的问题！voidwalker&@Pooshonk:还没有..你的例子有任何演示链接吗？做得很好，但是在
