我将两个轴添加到SVG,但是,y轴在SVG的左侧渲染:
如果我将方向设置为“正确”'然后它被渲染,但在左侧:
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)
的左,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);

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);
