在干净的Linux安装之后，MongoDB不会启动(MongoDB wont start after clean Linux install)
我在Linux上安装MongoDB时遇到问题。 我只需要在本地安装MongoDB。 我从一个过时的版本（2.4.9）开始，所以我使用这些命令行删除整个旧版本：
sudo apt-get purge mongodb mongodb-clients mongodb-server mongodb-dev sudo apt-get purge mongodb-10gen sudo apt-get autoremove所以此时我的Linux Mint Qaina 17上没有安装MongoDB版本
我去了网站： http ： //docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/做了以下命令行，就像网站告诉我做的那样：
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10 echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list sudo apt-get update sudo apt-get install -y mongodb-org sudo service mongod start此刻我安装了MongoDB 2.6.5。 最新版本。 在我没有错误后，我重新启动终端。 这是我打字后输入终端的结果：sudo mongod

I have a problem with my MongoDB installation on Linux. I just need to install MongoDB local. I started with a outdated version (2.4.9), so I used these command lines to delete the entire old version:
sudo apt-get purge mongodb mongodb-clients mongodb-server mongodb-dev sudo apt-get purge mongodb-10gen sudo apt-get autoremoveSo at this moment I had no version of MongoDB installed on my Linux Mint Qaina 17
I went to the website: http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/ Did the following command lines, just like the websites told me to do:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10 echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list sudo apt-get update sudo apt-get install -y mongodb-org sudo service mongod startAt this moment I have MongoDB 2.6.5 installed. The latest version. After I got none error, I restart my terminal. This is my result in terminal after I typed: sudo mongod

不知道Python绑定，但Qwt 5.2提供了一个类QwtPlotRescaler，它提供类似“轴相等”的功能。
在Qwt 6.1中，您可以找到重新缩放器示例，其中显示了如何使用它。
Don't know about the Python bindings, but Qwt 5.2 offers a class QwtPlotRescaler, that offers something like the "axis equal" feature.
In Qwt 6.1 you find the rescaler example, that shows how to use it.
