我用D3.js繪製了一個折線圖。這是很好的淹沒,但有一點問題。問題是,y軸上的值沒有顯示在相應的點上。線的形狀也是正確的。但它從相應的位置向上移動。這是我的代碼,我在哪裏做錯了什麼?爲什麼y軸值從折線圖上的實際點上移?
var margin = {top: 20, right: 100, bottom: 30, left: 100},
width = 960 - margin.left - margin.right,
height = 500 - margin.top - margin.bottom;
var dataset = [
{x: 0, y: true},
{x: 1, y: true},
{x: 2, y: false},
{x: 3, y: true},
{x: 4, y: true},
{x: 5, y: true},
{x: 6, y: true},
];
var xScale = d3.scale.linear()
.domain([0, d3.max(dataset, function(d){ return d.x; })])
.range([0, width]);
var yScale = d3.scale.ordinal()
.rangeRoundBands([0,height]);
/*var yScale = d3.scale.linear()
.domain([0, 1])
.range([height, 0]);
*/
var xAxis = d3.svg.axis()
.scale(xScale)
.orient("bottom")
.innerTickSize(-height)
.outerTickSize(0)
.tickPadding(10);
var yAxis = d3.svg.axis()
.scale(yScale)
.orient("left")
.innerTickSize(-width)
.outerTickSize(0)
.tickPadding(10);
yScale.domain(dataset.map(function(d) {return d.y;}));
var line = d3.svg.line()
.x(function(d) { return xScale(d.x); })
.y(function(d) { return yScale(d.y); });
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("path")
.data([dataset])
.attr("class", "line")
.attr("d", line);
.axis path,
.axis line{
fill: none;
stroke: black;
}
.line{
fill: none;
stroke: blue;
stroke-width: 2px;
}
.tick text{
font-size: 12px;
}
.tick line{
opacity: 0.2;
}

感謝您的任何意見來解決這個問題。
謝謝... :)它爲我工作.. +1 –
