我希望每个条的实际值以此处显示的方式显示在顶部
我正在多条形图上尝试这个。
在任何地方都找不到参考。
如何在堆叠多条形图中显示值的重复- nvd3 Graphs
您可以在https://gist.github.com/topicus/217444acb4204f364e46 自行实施修复
编辑:如果 github 链接被删除,则复制代码:
// You need to apply this once all the animations are already finished. Otherwise labels will be placed wrongly.
d3.selectAll('.nv-multibar .nv-group').each(function(group){
var g = d3.select(this);
// Remove previous labels if there is any
g.selectAll('text').remove();
g.selectAll('.nv-bar').each(function(bar){
var b = d3.select(this);
var barWidth = b.attr('width');
var barHeight = b.attr('height');
g.append('text')
// Transforms shift the origin point then the x and y of the bar
// is altered by this transform. In order to align the labels
// we need to apply this transform to those.
.attr('transform', b.attr('transform'))
.text(function(){
// Two decimals format
return parseFloat(bar.y).toFixed(2);
})
.attr('y', function(){
// Center label vertically
var height = this.getBBox().height;
return parseFloat(b.attr('y')) - 10; // 10 is the label's magin from the bar
})
.attr('x', function(){
// Center label horizontally
var width = this.getBBox().width;
return parseFloat(b.attr('x')) + (parseFloat(barWidth) / 2) - (width / 2);
})
.attr('class', 'bar-values');
});
});
显然这还不存在。有一个问题(https://github.com/novus/nvd3/issues/150)已关闭,因为这(显然)难以实施。
