我有三个单选按钮,它们改变了我的d3线图的x轴上的值。我已经成功地改变了比例尺,但不是X轴标签。到处看,我只看到滴答标签的信息,而不是轴标签(在gif“分钟”中)。更新D3轴标签
我已经成功地得以更新,从而重新缩放轴与下面的代码,但无法弄清楚如何更改标签。
function updateGraph(graphData, timeScale){
yDomain = d3.extent(graphData, function(d){return Number(d.amt)});
switch(timeScale) {
case 'min':
xDomain = d3.extent(graphData, function(d){return Number(d.min)});
break;
case 'hour':
xDomain = d3.extent(graphData, function(d){return Number(d.hour)});
break;
case 'day':
xDomain = d3.extent(graphData, function(d){return Number(d.day)});
break;
default: break;
}
//Make the scale for the graphs dynamic
yScale.domain(yDomain);
xScale.domain(xDomain);
vis = d3.select('#visualisation').transition();
//add axes with proper scale, orientation, and position
var line = d3.svg.line()
.x(function(d){
switch(timeScale) {
case 'min':
return xScale(d.min);
break;
case 'hour':
return xScale(d.hour);
break;
case 'day':
return xScale(d.day);
break;
default: break;
}
})
.y(function(d){
return yScale(d.amt);
})
.interpolate('basis');
var xAxisLabel = function(){
switch(timeScale) {
case 'min':
return 'Minute';
break;
case 'hour':
return 'Hours';
break;
case 'day':
return 'Day';
break;
default: break;
}
}
vis.select('.line')
.duration(750)
.attr('d', line(graphData))
vis.select('.xaxis')
.duration(750)
.call(xAxis);
vis.select('.yaxis')
.duration(750)
.call(yAxis);
//Tried to hardcode with 'sugar' to no avail, would eventually like to use xAxisLabel declared above.
vis.select('.text')
.duration(750)
.text('sugar');
}
我设置的文本时,我第一次提出用下面的代码的图形:
vis.append('text')
.attr('text-anchor', 'middle') // this makes it easy to centre the text as the transform is applied to the anchor
.attr('transform', 'translate('+ (WIDTH/2) +','+(HEIGHT+(MARGINS.bottom/3))+')') // centre below axis
.text(xAxisLabel);
创建文本的'var'是什么?你只需要做'someVariable.text(“你的文本”)'。现在,您正在选择一个DOM元素。 –
嘿赫拉尔多,我会相应地更新我的问题。 –
