在SVG之外的d3轴渲染

我将两个轴添加到SVG,但是,y轴在SVG的左侧渲染:

Y Axis off to the left edge

如果我将方向设置为“正确”'然后它被渲染,但在左侧:

Y Axis present

代码是这样的:

'use strict';

var margins = {top: 50, bottom: 50, left: 50, right: 50};
var dateFormat = d3.time.format('%d-%b-%y')
var svg = d3.select('.graph');

var svgWidth = parseInt(svg.style('width')),
    svgHeight = parseInt(svg.style('height'));

var height = svgHeight - margins.top - margins.bottom,
    width = svgWidth - margins.left - margins.right;

var dates = [], closes = [];

data.forEach(function(item) {
    dates.push(dateFormat.parse(item.date));
    closes.push(item.close);
});

var xScale = d3.time.scale().range([0, width]).domain([d3.min(dates), d3.max(dates)]);
var yScale = d3.scale.linear().range([height, 0]).domain([0, d3.max(closes)]);

var xAxis = d3.svg.axis().scale(xScale).orient('bottom');
var yAxis = d3.svg.axis().scale(yScale).orient('right');

svg.append("g")
    .attr("class", "x axis")
    .call(xAxis);

svg.append("g")
    .attr("class", "y axis")
    .call(yAxis);

任何g的默认位置为(0, 0).orient('left')表示轴位于(0, 0),即在场外。您需要在包含轴的transform元素上手动设置g

yAxis.orient('left');
svg.append('g')
  .attr('class', 'y axis')
  .attr('transform', 'translate(' + [margins.left, margins.top] + ')');
  .call(yAxis);

我会仔细研究一些triedtrue示例。

使用推荐的表单,您缺少“绘图区”g元素。

// have an SVG that is the drawing area width/height plus margins
// you don't show your mark-up but it looks like your code is ok 

// append a `g` element and translate it to your margins
// you'll do all your drawing to the g element
svg = svg.append("g")
  .attr("transform", "translate(" + margins.left + "," + margins.top + ")");

// append axis to this g
// your y-axis will be in the margin, so adjust margins.left to fit
svg.append("g")
  .attr("class", "y axis")
  .call(yAxis);
