尝试添加多个D3图形 [英] Trying to add multiple D3 graphs
问题描述
我想弄清楚如何在我的网站上添加2个或更多图表。我目前正在使用区域图和饼图。如果我禁用其中的一个,那么另一个工作正常,但当我尝试同时使用这两个,它停止工作。
I'm trying to figure out how to include 2 or more graphs on my website. I am currently using the Area Graph and the Pie Graph. If I disable one of them, then the other works fine, but when I try to use both at the same time, it stops working.
区域图的JS代码
var margin = { top: 0, right: 0, bottom: 30, left: 50 },
width = 670 - margin.left - margin.right,
height = 326 - margin.top - margin.bottom;
var parseDate = d3.time.format("%d-%b-%y").parse;
var x = d3.time.scale()
.range([0, width]);
var y = d3.scale.linear()
.range([height, 0]);
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom");
var yAxis = d3.svg.axis()
.scale(y)
.orient("left");
var svg = d3.select("#watLenYearGra").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 + ")");
var area = d3.svg.area()
.x(function (d) { return x(d.date); })
.y0(height)
.y1(function (d) { return y(d.close); });
$("#watLenYear").click(function () {
$("#watLenYearGra").slideToggle("fast");
});
d3.csv("data.csv", function (error, data) {
data.forEach(function (d) {
d.date = parseDate(d.date);
d.close = +d.close;
});
x.domain(d3.extent(data, function (d) { return d.date; }));
y.domain([0, d3.max(data, function (d) { return d.close; })]);
svg.append("g")
.attr("class", "x axis")
.attr("transform", "translate(0," + height + ")")
.call(xAxis);
svg.append("g")
.attr("class", "y axis")
.call(yAxis)
.append("text")
.attr("transform", "rotate(-90)")
.attr("y", 6)
.attr("dy", ".71em")
.style("text-anchor", "end")
.text("Price ($)");
svg.append("path")
.datum(data)
.attr("class", "area")
.attr("d", area);
});
饼图的JS代码
var width = 670,
height = 326,
radius = Math.min(width, height) / 2;
var color = d3.scale.ordinal()
.range(["#98abc5", "#8a89a6", "#7b6888", "#6b486b", "#a05d56", "#d0743c", "#ff8c00"]);
var arc = d3.svg.arc()
.outerRadius(radius - 10)
.innerRadius(0);
var pie = d3.layout.pie()
.sort(null)
.value(function (d) { return d.population; });
var svg = d3.select("#watLenSzGra").append("svg")
.attr("width", width)
.attr("height", height)
.append("g")
.attr("transform", "translate(" + width / 2 + "," + height / 2 + ")");
$("#watLenSz").click(function () {
$("#watLenSzGra").slideToggle("fast");
});
d3.csv("data1.csv", function (error, data) {
data.forEach(function (d) {
d.population = +d.population;
});
var g = svg.selectAll(".arc")
.data(pie(data))
.enter().append("g")
.attr("class", "arc");
g.append("path")
.attr("d", arc)
.style("fill", function (d) { return color(d.data.age); });
g.append("text")
.attr("transform", function (d) { return "translate(" + arc.centroid(d) + ")"; })
.attr("dy", ".35em")
.style("text-anchor", "middle")
.text(function (d) { return d.data.age; });
});
我认为问题在于变量的范围(特别是svg变量,名称)。现在我有单独的JS文件中的这些代码集,我将它们链接在HTML文件中我的body标记的底部。
I think the problem lies with the scope of the variables (specifically the svg variable since they have the same name). Right now I have these sets of code in separate JS files, and I link them at the bottom of my body tag in the HTML file.
如何限制这些变量'范围到他们的文件?这是甚至问题吗?感谢
How can I limit these variables' scope to their files? Is that even the problem? Thanks

如果您使用闭包:
(function() {
var margin = { top: 0, right: 0, bottom: 30, left: 50 },
width = 670 - margin.left - margin.right,
height = 326 - margin.top - margin.bottom;
var parseDate = d3.time.format("%d-%b-%y").parse;
var x = d3.time.scale()
.range([0, width]);
var y = d3.scale.linear()
.range([height, 0]);
var xAxis = d3.svg.axis()
.scale(x)
.orient("bottom");
var yAxis = d3.svg.axis()
.scale(y)
.orient("left");
var svg = d3.select("#watLenYearGra").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 + ")");
var area = d3.svg.area()
.x(function (d) { return x(d.date); })
.y0(height)
.y1(function (d) { return y(d.close); });
$("#watLenYear").click(function () {

})();
