[英]Why does not this chart d3.js work with require.js?
I've made a pie-chart and trying to display it on a page using require.js but can't do it correctly. 我制作了一个饼图,并尝试使用require.js将其显示在页面上,但无法正确执行。 Firebug shows that there is svg on this page with certain size and the page is empty. Firebug显示此页面上有特定大小的svg,并且页面为空。 I tried to implement other moodules - they work well. 我尝试实现其他情绪-它们效果很好。
File main.js: 文件main.js:
require.config({
paths: {
'd3': "http://d3js.org/d3.v3.min"
},
shim: {
'd3': {exports:'d3'}
}
});
require([
'd3',
'pie-chart'
], function (d3, piechart) {
d3.select("body").append("h1").text("Successfully loaded D3 version " + d3.version);
d3.select("body").append("svg");
});
File pie-chart.js: 文件pie-chart.js:
define('pie-chart', function () {
var width = 960,
height = 500,
radius = Math.min(width, height) / 2;
var legendRectSize = 18;
var legendSpacing = 4;
var color = d3.scale.ordinal()
.range(["#98abc5", "#8a89a6", "#7b6888", "#6b486b", "#a05d56", "#d0743c", "#ff8c00"]);
var percentageFormat = d3.format("%");
var arc = d3.svg.arc()
.outerRadius(radius - 10)
.innerRadius(0);
var pie = d3.layout.pie()
.sort(null)
.value(function(d) {
return d.values;
});
var svg = d3.select("body").append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width / 2 + "," + height / 2 + ")");
d3.json("staff.json", function(error, json_data) {
var data = d3.nest()
.key(function(d) {
return d.Position;
})
.rollup(function(d) {
return d.length;
}).entries(json_data);
data.forEach(function(d) {
d.percentage = d.values / json_data.length;
});
console.log(data)
console.log("data variable", data);
console.log("pie(data)", pie(data));
var g = svg.selectAll(".arc")
.data(pie(data))
.enter().append("g")
.attr("class", "arc")
.on('mouseover', function() {
var current = this;
var others = svg.selectAll(".arc").filter(function(el) {
return this != current
});
others.selectAll("path").style('opacity', 0.8);
})
.on('mouseout', function() {
var current = this;
d3.select(this)
.style('opacity', 1);
var others = svg.selectAll(".arc").filter(function(el) {
return this != current
});
others.selectAll("path").style('opacity', 1);
});
g.append("path")
.attr("d", arc)
.style("fill", function(d, i) {
return color(d.data.key);
});
g.append("text")
.attr("transform", function(d) {
return "translate(" + arc.centroid(d) + ")";
})
.attr("dy", ".35em")
.style("text-anchor", "middle")
.text(function(d) {
console.log("d is", d);
return percentageFormat(d.data.percentage);
});
var legend = d3.select("body").append("svg")
.attr("class", "legend")
.selectAll("g")
.data(data)
.enter().append("g")
.attr("transform", function(d, i) { return "translate(0," + i * 20 + ")"; });
legend.append("rect")
.attr("width", 18)
.attr("height", 18)
.style("fill", function(d, i) {
return color(d.key);
});
legend.append("text")
.attr("x", 24)
.attr("y", 9)
.attr("dy", ".35em")
.text(function(d) { return d.key; });
});
});
File d3.js I wrapped this way: 我用这种方式包装文件d3.js:
define('d3', function () {
// require.js code
});
d3 is not dependent on JQuery. d3不依赖于JQuery。 I removed the jquery from your plunk, also you do not need the shim attribute. 我从您的杂物中删除了jquery,您也不需要shim属性。 Your main.js should be something like this: 您的main.js应该是这样的:
require.config({
paths: {
'd3': "https://cdnjs.cloudflare.com/ajax/libs/d3/3.5.9/d3.min"
}
});
require([
'd3',
'pie-chart'
], function ( d3, $, piechart) {
});
Here is the working plunk link: http://plnkr.co/edit/Le4tpejMvPxLA08isacW?p=preview 这是工作正常的链接: http ://plnkr.co/edit/Le4tpejMvPxLA08isacW? p= preview
