abi*_*964 10 javascript jquery morris.js
我有一个morris.js条形图.我想放在count这张图的顶部.我调查了morris.js酒吧文档,找不到任何内容.
在悬停时它应该显示value但在栏顶部应该显示count.有没有办法做到这一点?像给定图像的东西

这是我的代码
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";
}
});

我在寻找同样的解决方案时发现了这个问题.这是在javascript/jquery中完成的.
我可以与您分享我正在使用的代码,我通过试验,错误和研究发现了这些代码.
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 "Arial"" 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));
});

输出看起来像这样.
但是你可以尝试的是改变这里的值
var newY = parseFloat( $(this).attr('y') - 20 );

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

这种变化未经测试,但将作为一个良好的起点.
问候 :)
您可以扩展Morris来实现此目的。请参考此答案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原型,添加以下行(在其他行之前):
if (this.options.labelTop && !this.options.stacked) {
label = this.drawLabelTop((left + (barWidth / 2)), top - 10, row.y[sidx]);
textBox = label.getBBox();
_results.push(textBox);
}

然后labelTop在您的Morris Bar配置中将该属性设置为true:
labelTop: true
