如何使用d3.csv将csv文件中的第一行条目放入表标题？
这是我的csv数据文件:
Surname,Name,Phone,eMail
Stupich,Andrew,719-817-2323,Andy@foo.org
Miles,Wally,719-415-7177,Wally@foo.org
McLaren,Brenda,719-817-1096,Brenda@foo.org
这是我的html文件:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>D3.csv Demo</title>
<style type="text/css">
body {
margin-left: 4%;
margin-right: 4%;
}
table {
border-collapse: collapse;
border: 2px #000 solid;
}
th {
border: 1px #F00 solid;
text-align: center;
font-weight: bold;
}
td {
border: 1px #00F solid;
text-align: center;
padding: 5px;
}
</style>
<script type="text/javascript" src="http://mbostock.github.com/d3/d3.js"></script>

d3.text("DemoData.csv", function(datasetText) {
var parsedCSV = d3.csv.parseRows(datasetText);
var sampleHTML = d3.select("#viz6")
.append("table")
.selectAll("tr")
.data(parsedCSV)
.enter().append("tr")
.selectAll("td")
.data(function(d){return …在Linux Mint'Mate'17环境中使用Python 2.7和Tkinter
我是OOP的新手,并不了解如何将持久值传递给类实例; 在此代码中,当我在第20行和第22行使用Pin_ID时,会生成"全局未定义"错误:
1 #!/usr/bin/env python
2 import Tkinter as tk
3
4 root = tk.Tk()
5
6 class cbClass:
7 def __init__(self, Pin_ID):
8 self.cb_Txt=tk.StringVar()
9 self.cb_Txt.set("Pin " + Pin_ID + " OFF")
10 self.cb_Var = tk.IntVar()
11 cb = tk.Checkbutton(
12 root,
13 textvariable=self.cb_Txt,
14 variable=self.cb_Var,
15 command=self.cbTest)
16 cb.pack()
17
18 def cbTest(self):
19 if self.cb_Var.get():
20 self.cb_Txt.set("Pin " + Pin_ID + " ON")
21 else:
22 self.cb_Txt.set("Pin " + Pin_ID + " OFF")
23 …
