问题描述
您好,我刚刚开始使用d3作为数据可视化工具,我正在学习以下教程:
Hi i have just started on using d3 as a data visualisation tool and I was following this tutorial: http://bost.ocks.org/mike/bar/
但是,我的代码:
<!DOCTYPE html>
<meta charset="utf-8">
<style>
.chart rect {
fill: steelblue;
}
.chart text {
fill: white;
font: 10px sans-serif;
text-anchor: end;
}
</style>
<svg class="chart"></svg>
<script src="http://d3js.org/d3.v3.min.js"></script>
<script>
var width = 420,
barHeight = 20;
var x = d3.scale.linear()
.range([0, width]);
var chart = d3.select(".chart")
.attr("width", width);
d3.tsv("data.tsv", type, function(error, data) {
x.domain([0, d3.max(data, function(d) { return d.value; })]);
chart.attr("height", barHeight * data.length);
var bar = chart.selectAll("g")
.data(data)
.enter().append("g")
.attr("transform", function(d, i) { return "translate(0," + i * barHeight + ")"; });
bar.append("rect")
.attr("width", function(d) { return x(d.value); })
.attr("height", barHeight - 1);
bar.append("text")
.attr("x", function(d) { return x(d.value) - 3; })
.attr("y", barHeight / 2)
.attr("dy", ".35em")
.text(function(d) { return d.value; });
});
function type(d) {
d.value = +d.value; // coerce to number
return d;
}
</script>
其中教程指出使用d3.tsv不工作,与harrd编码的html相比。任何人都可以在这方面有一些光吗?我已将 data.tsv
文件放在同一个文件夹中。
where the tutorial says to use d3.tsv does not work, as compared to a harrd coded html. can anyone shed some light on this? I've placed the data.tsv
file in the same folder already.
这是我的.tsv文件:
This is my .tsv file:
name value
Locke 4
Reyes 8
Ford 15
Jarrah 16
Shephard 23
Kwon 42
推荐答案
如果您从计算机加载tsv文件时使用chrome,则需要按照
If you are loading the tsv file with chrome from your computer, you need to setup a server on your computer as explained in the documentation
python -m SimpleHTTPServer 8888 &
