问题 I'm new to using NetworkX library with Python. Let's say that I import a Pajek-formatted file: import networkx as nx G=nx.read_pajek("pajek_network_file.net") G=nx.Graph(G) The contents of my file are (In Pajek, nodes are called "Vertices"): *Network *Vertices 6 123 Author1 456 Author2 789 Author3 111 Author4 222 Author5 333 Author6 *Edges 123 333 333 789 789 222 222 111 111 456 Now, I want to calculate all the shortest path lengths between the nodes in my network, and I'm using this function

C# wpf 中Label的ToolTip的使用

阅读更多关于 C# wpf 中Label的ToolTip的使用

问题背景，就是想啊，这个有时候，wpf 中label里面的东西显示不全，如果将label调大，又不好看，怎么办呢，这个时候，类似于mfc中的ToolTip，或者安卓中的Toast来辅助显示，那将是很棒的。琢磨了下，来个委托，完美解决。来看看代码： 1 在你的类里面加上这两个声明 public delegate void StatusReport ( string s ) ; //委托原型声明 public StatusReport m_srt = null ; 2 在你的构造函数里面加上这个的初始化 m_srt = new StatusReport ( DoReportStatus ) ; 3 在你的类里面还要加上委托的执行函数 public void DoReportStatus ( string s ) { Label_StatusReport . Content = s ; Label_StatusReport . ToolTip = s ; } 4 可以留个接口，方便使用，接口内部调用委托 public void ReportStatus ( string s ) { this . DisPatcher . BeginInvoke ( m_srt , s ) ; } 5 具体效果嘛，就是这个label显示的东西如果显示不全，那么你鼠标在上面停下，就会提示全，当然

How to keep axis labels in one side and axis title in another using ggplot2

问题 I wonder if it is possible (I know it is) to keep the plot's axis labels in one side of the plot and the plot's axis title in the opposite side, specifically in a discrete geom_tile() plot as follows: 回答1: You can use sec.axis = dup_axis() inside scale_x_*() to duplicate both axis then remove what you don't need inside theme() . ggplot(mtcars, aes(x=mpg, y=hp)) + geom_point() + labs(title="mpg vs hp") + scale_y_continuous(position = 'right', sec.axis = dup_axis()) + #remember to check this

Django之Form

阅读更多关于 Django之Form

Form介绍我们之前在HTML页面中利用form表单向后端提交数据时，都会写一些获取用户输入的标签并且用form标签把它们包起来。与此同时我们在好多场景下都需要对用户的输入做校验，比如校验用户是否输入，输入的长度和格式等正不正确。如果用户输入的内容有错误就需要在页面上相应的位置显示对应的错误信息.。 Django form组件就实现了上面所述的功能。总结一下，其实form组件的主要功能如下: 生成页面可用的HTML标签对用户提交的数据进行校验保留上次输入内容普通方式手写注册功能 views.py # 注册 def register(request): error_msg = "" if request.method == "POST": username = request.POST.get("name") pwd = request.POST.get("pwd") # 对注册信息做校验 if len(username) < 6: # 用户长度小于6位 error_msg = "用户名长度不能小于6位" else: # 将用户名和密码存到数据库 return HttpResponse("注册成功") return render(request, "register.html", {"error_msg": error_msg}) login.html <!DOCTYPE
