我有一个问题，我如何绘制图表，但是来自数据的 las 2 数组忽略了来自 css 的填充。
我这里有代码:
<html>
<head>
<title></title>
<script src="d3.min.js"></script>
<style>
body {
font: 10px sans-serif;
}
.grid path {
stroke-width: 0;
}
.axis path {
fill: #E0E0E0;
stroke: #bbb;
shape-rendering: crispEdges;
}
.axis text {
fill: #000;
}
.axis line {
stroke: #e7e7e7;
shape-rendering: crispEdges;
}
.axis .axis-label {
font-size: 10px;
}
.line {
stroke-width: 1;
}
</style>
</head>
<body>
<script>
var data = [
//VERD
[{'x':15000,'y':0}, {'x':15000,'y':130},{'x':40000,'y':130},{'x':40000,'y':0},
{'x':60000,'y':0},{'x':60000,'y':130},{'x':70000,'y':130},{'x':70000,'y':0},],
// GRIS PARADA

//TARONJA TRABAJO
[{'x':16000,'y':40},{'x':16000,'y':80}, {'x':37000,'y':80}, {'x':37000,'y':40}],
//BLAU RALENTI
[{'x':17000,'y':0},{'x':17000,'y':40},{'x':35000,'y':40},{'x':35000,'y':0} ],
//LINEA VELOCITAT
[{'x':10000,'y':0},{'x':12000,'y':80}, {'x':15000,'y':70}, {'x':17000,'y':80},{'x':19000,'y':100},

{'x':50000,'y':47}, {'x':55000,'y':88}, {'x':59000,'y':25}, {'x':66000,'y':0}],
//LINEA TEMPERATURA
[{'x':10000,'y':0},{'x':12000,'y':20}, {'x':15000,'y':15}, {'x':17000,'y':18},{'x':19000,'y':17},
{'x':20000,'y':15}, {'x':27000,'y':19}, {'x':33000,'y':12}, {'x':37000,'y':21}, {'x':40000,'y':23}, {'x':45000,'y':15},
{'x':50000,'y':18}, {'x':55000,'y':19}, {'x':59000,'y':21}, {'x':66000,'y':20}]
];
var colors = [
'green',
'gray',
'orange',
'blue',
'red'
]
var margin = {top: 5, right: 30, bottom: 30, left: 50},
width = 960 - margin.left - margin.right,
height = 200 - margin.top - margin.bottom;
var x = d3.scale.linear()
.domain([0, 86400])
.range([0, width]);
var y = d3.scale.linear()
.domain([0, 140])
.range([height, 0]);
var xAxis = d3.svg.axis()
.scale(x)
.ticks(10)
.tickSize(-height)
.tickPadding(10)
.tickSubdivide(true)
.orient("bottom");
var yAxis = d3.svg.axis()
.scale(y)
.ticks(5)
.tickPadding(10)
.tickSize(-width)
.tickSubdivide(true)
.orient("left");
var svg = d3.select("body").append("svg")
.attr("width", width + margin.left + margin.right)
.attr("height", height + margin.top + margin.bottom)
.append("g")
.attr("transform", "translate(" + margin.left + "," + margin.top + ")");
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis);
svg.append("g")
.attr("class", "y axis")
.call(yAxis);
svg.append("g")
.attr("class", "y axis")
.append("text")
.attr("class", "axis-label")
.attr("transform", "rotate(-90)")
.attr("y", (-margin.left) + 10)
.attr("x", -height/2)
.text('KM/H');
svg.append("clipPath")
.attr("id", "clip")
.append("rect")
.attr("width", width)
.attr("height", height);
var line = d3.svg.line()
.interpolate("linear")
.x(function(d) { return x(d.x); })
.y(function(d) { return y(d.y); });
svg.selectAll('.line')
.data(data)
.enter()
.append("path")
.attr("class", "line")
.attr("clip-path", "url(#clip)")
.attr('fill', function(d,i){
return colors[i%colors.length];
})
.attr("d", line);
</script>
</body>
</html>
这里是实际结果: Actual
我需要这个结果:
如何在没有填充的情况下显示最后一行？ 真的谢谢大家。
最佳答案
当你想要<path>要排队，请使用 stroke属性而不是 fill在 SVG 中。你应该通过 index 控制特定数据在 attr 回调函数中。
svg.selectAll('.line')
.data(data)
.enter()
.append("path")
.attr("class", "line")
.attr("clip-path", "url(#clip)")
.attr('fill', function(d, i) {
return i < 4 ? colors[i % colors.length] : 'none';
})
.attr('stroke', function (d, i) {
return i >= 4 ? colors[i % colors.length] : 'none';
})
.attr("d", line);
