我正准备进行演示,我有一些3D matplotlib数字的示例图.但是,网格线太亮,无法在投影图像上看到.

我尝试使用适用于2D数字的网格方法:

points = (5*np.random.randn(3, 50)+np.tile(np.arange(1,51), (3, 1))).transpose()
fig = plt.figure(figsize = (10,10))
ax = fig.add_subplot(111, projection='3d') 
ax.scatter(points[:,0], points[:,1], points[:,2])
ax.view_init(elev=0., azim=0)
ax.set_ylim([0, 60])
ax.set_zlim([0, 60])
ax.set_xlim([0, 60])
ax.set_zlabel('Cytokine')
ax.set_ylabel('Parameter')
ax.grid(linewidth=20)

但这似乎不适用于3D数字.有什么建议？

众所周知,在使用AngularJS时,必须在指令内操作DOM元素.

但是,在某些用例中,似乎可以接受在服务中操作DOM.Misko Hevery在这里谈论这个.您还可以在Bootstrap UI对话框中找到示例.

Misko的解释相当含糊,所以我想知道你如何确定何时需要将DOM放在服务中而不是指令中.

我想在单击按钮时更改标题的颜色.这是我的代码,但它不起作用,我无法弄清楚为什么不...

<div id="about">About Snakelane</div>

<input type="image" src="http://www.blakechris.com/snakelane/assets/about.png" onclick="init()" id="btn">

和我的js ......

var about;   
function init() { 
    about = document.getElementById("about").innerHTML;
    about.style.color = 'blue';
}

提前致谢!

Some browsers (Firefox, Chrome) by design doesn't clean session cookies when you close them, if you set some kind of remember me switch (for example in FF go to Options->General->When Firefox starts->Show my windows and tabs from last time). It is a problem for our client (government agency...) while I do have absolute control over http server, I have no control over browser settings. The scenario is - they're used to share computer accounts, however they shouldn't be able to …

我有以下要在F#中使用的C#类

using System;
using System.Collections.Generic;
using System.Text;

namespace DataWrangler.Structures
{
    public enum Type { Trade = 0, Ask = 1, Bid = 2 }

    public class TickData
    {
        public string Security = String.Empty;
        public uint SecurityID = 0;
        public object SecurityObj = null;
        public DateTime TimeStamp = DateTime.MinValue;
        public Type Type;
        public double Price = 0;
        public uint Size = 0;
        public Dictionary<string, string> Codes;
    }
}

我想在F#中创建它的一个实例.我用来执行此操作的代码位于f#脚本文件中

#r @"C:\Users\Chris\Documents\Visual Studio 2012\Projects\WranglerDataStructures\bin\Debug\WranglerDataStructures.dll"

open System
open System.Collections.Generic;
open System.Text;
open DataWrangler.Structures …

我想为某些JPanels 添加填充.我找到了这个答案:https://stackoverflow.com/a/5328475/1590323

它适用于没有边框的面板.但是,我如何为已经有边框的面板做到这一点？(TitledBorder在这种情况下是A )

我试过了:

JPanel mypanel = new MyPanel(); // Panel that I am going to add a TitledBorder to, but needs padding
mypanel.setBorder(new EmptyBorder(10,10,10,10));
JPanel mypanel_container = new JPanel();
TitledBorder border = BorderFactory.createTitledBorder(BorderFactory.createRaisedBevelBorder(), "My panel");
border.setTitleJustification(TitledBorder.LEADING);
mypanel_container.setBorder(border);
mypanel_container.add(mypanel);
this.add(mypanel_container);

(简而言之:在EmptyBorder应该具有a的TitledBorder面板中TitledBorder添加,然后使用该面板创建另一个面板并将第一个面板添加到该面板,然后使用该面板)

但后来我得到了太大的填充,忽略了构造函数的值EmptyBorder.

那么如何在带图形边框的JPanel中添加填充？

我在我的Cocoa应用程序中做了一个简单的文件打开面板.我启用了权利和应用沙盒.但是在OS X 10.9上,当应用程序使用时打开一个对话框时NSOpenPanel,它会崩溃:

特定于应用程序的信息:
因未捕获的异常'NSObjectNotAvailableException'而终止应用程序,原因:'service com.apple.appkit.xpc.openAndSavePanelService无法代表由于{"proxy-communications-error"="错误而初始化NSOpenPanelService的实例Domain = NSCocoaErrorDomain代码= 4099 \"\ U041d\U0435\U0443\U0434\U0430\U043b\U043e\U0441\U044c\U0443\U0441\U0442\U0430\U043d\U043e\U0432\U0438\U0442\U044c\U0441\U0432\U044f\U0437\U044c\U0441\U043f\U0440\U043e\U0433\U0440\U0430\U043c\U043c\U043e\U0439-\U043f\U043e\U043c\U043e\U0449\U043d\U0438\U043a\U043e\U043c. \"(连接在此过程中无效.)UserInfo = 0x61000047dc00 {NSDebugDescription =此过程中的连接无效.}"; }"

资源:

self.panel = [NSOpenPanel openPanel];
panel.delegate = self;
panel.canChooseDirectories = YES;
panel.canChooseFiles = NO;

谁看过这个吗？

我正在尝试javac永久地为它的java vm 设置堆大小.我已经把我的JAVA_OPTS给-Xmx64m我打电话伟大的工程java,但没有javac.我仍然遇到堆大小问题.我可以在.bashrc中设置一个不同的变量来永久更改吗？

当我运行javac -J-Xmx64m它时效果很好.所以我只需要一种方法使该-J-Xmx64m选项永久化.

仅供参考 - 我正在使用OpenJDK 1.7运行Ubuntu 11.10

所以我正在做一些重构,我真的很烦恼,我没有预先得到所有的错误.如何增加限制或删除限制,以便编译器输出它可以找到的所有错误？

我有以下代码,我希望只在我的浏览器中加载页面,用IIS 7运行它.

<%@ Page Language="C#" Debug="true" %>
<%
using System;

protected string callRotate()
{
    ProcessStartInfo info = new ProcessStartInfo();
    string[] arguments = { "arg1" , "arg2" };
    info.FileName = "ConsoleApplication1";

    Process process = Process.Start(info.FileName, arguments);
    Process.Start(info);
}
%>

这是我在浏览器中遇到的错误:

    Server Error in '/' Application.
