Docker 是一个容器工具，提供虚拟环境。解决了软件的环境配置和依赖问题，让软件可以带环境和依赖的安装。 Docker 将应用程序与该程序的依赖，打包在一个文件里面。运行这个文件，就会生成一个虚拟容器。程序在这个虚拟容器里运行，就好像在真实的物理机上运行一样。有了 Docker，就不用担心环境问题。 1. 注册 docker 账号 想要使用docker，先注册一个docker账号， 注册docker账号 。 注册完成后，登录到 docker hub 就能看到自己的 docker 镜像了，docker hub 是 docker 官方存放 docker 镜像的仓库。如我的 hub 下列出了我push的镜像 2. docker 的安装 注册完docker账号，然后安装docker： window 10 Mac OS window 10 安装 docker 19.03.2 百度网盘地址 安装完成后可以通过命令 docker version 来查看docker的版本号 C:\Users\lixinjie>docker version Client: Docker Engine - Community Version: 19.03.2 API version: 1.40 Go version: go1.12.8 Git commit: 6a30dfc Built: Thu Aug 29 05

I am using JFreeChart to display a value for each day of a month. Now I want to have my x-axis display the weeks in a month instead of the days. At the moment the values for my graph are double on the y-axis and int on the x axis. Timestamp ts = a.getTimestamp(); Double val = a.getVal(); series1.add(ts.getDate(), val); I am using plot.getDomainAxis().setRange(0, 31); to set the range for the days to one month and xax.setTickUnit(new NumberTickUnit(7)); for the x-axis to display the ticks at the right position. Instead of displaying the days (0, 7, 14, 21, 28) i want them to be weeks (0, 1, 2,
