分面设置在ggplot2应该也是要经常用到的一项画图内容,在数据对比以及分类显示上有着极为重要的作用, 下面是两个经常要用到的分面函数. facet_wrap(facets, nrow = NULL, ncol = NULL, scales = "fixed", shrink = TRUE, as.table = TRUE, drop = TRUE) facet_grid(facets, margins = FALSE, scales = "fixed", spac

cacti气象图能够非常直观的看到各个节点的流量.这里用的是CactiEZ中文版 V10 1.调整气象图大小 默认有一个1024像素的背景图可选, 这里我们须要新增一个1600像素的背景图. 背景图自己准备好后,放到cactiserver气象图的位置 /var/www/html/plugins/weathermap/images/ 这样在背景图形文件里就能够选择刚才上传的1600像素背景图了 2.批量调整节点位置 由于之前调整了背景图后,全部节点的位置有时显得不协调.如:总体偏左,右边空出一大块

我最近工作挺忙,距离上一次写博客转眼已经过了一个多月,每次学到和用到点新东西,其实都有分享的欲望,但奈何文笔太差,而一篇文章包括构思,排版,修改发布的时间最少要花费2个小时(这其中还不包括写完后未保存,突然关掉浏览器的惨剧…),但是今天不知怎么的突然头脑发热,决定把睡觉的2个小时用来写篇博客(请原谅我放荡不羁爱睡觉zZ...). 最近做的一个项目是为某企业做得一个门店拜访APP.需要用到拍照上传的功能.刚开始确定需求的时候,客户只要求实现拍照上传的功能,这个简单,直接调用系统的拍照不就行了,代码

我们在给app切图的时候不知道告诉ui启动图标切多大,其实你新建一个android项目就知道应该切多大了.新建一个项目会产生几种大小的启动图标. 我把各个文件夹下的ic_launcher.png文件都查看了下大小,得出如下值: 1.drawable-hdpi  72*72 2.drawable-mdpi  48*48 3.drawable-xhdpi 96*96 4.drawable-xxhdpi 144*144 看到上面的参数我相信大家都知道启动icon切多大了.

处于布局省事考虑,通常会用splitcontainer进行总体的布局,例如: 默认情况下,splitcontainer在运行时会根据上下文自动调整每个panel的大小,但大部分情况下,其实我们希望左边或者上面部分是固定的,所以需要设置如下: IsSpliterFixed属性设为False FixedPannel属性设为Pannel1(要固定的面板的名称)

最近写了一个项目,写页面的结构,html树形结构是有header,container,footer部分,其中container部分是右侧栏是固定宽度,左侧是自适应宽度与屏幕高度. 第一次写的博客文章是container部分是左侧栏固定,右侧是自适应效果.左侧栏固定是很好写,但右侧栏固定却不很好写,以下是基本的结构与样式. <div class="container" style="overflow:hidden;"> <div class=&quo

A clique is a subset of vertices of an undirected graph such that every two distinct vertices in the clique are adjacent. A maximal clique is a clique that cannot be extended by including one more adjacent vertex. (Quoted from https://en.wikipedia.or

ggplot2绘图系统--图形分面 ggplot2的分面faceting,主要有三个函数: facet_grid facet_wrap facet_null (不分面) 1. facet_grid函数 facet_grid函数及参数: facet_grid(facets, #x~y, x+y~z margins = F, #仅展示组合数据 scales = 'fixed', #是否通用坐标轴,free_x/free_y/free space = 'fixed', #是否保持相同面积 shrink

Weibo is known as the Chinese version of Twitter. One user on Weibo may have many followers, and may follow many other users as well. Hence a social network is formed with followers relations. When a user makes a post on Weibo, all his/her followers

The "Hamilton cycle problem" is to find a simple cycle that contains every vertex in a graph. Such a cycle is called a "Hamiltonian cycle". In this problem, you are supposed to tell if a given cycle is a Hamiltonian cycle. Input Specif

A vertex cover of a graph is a set of vertices such that each edge of the graph is incident to at least one vertex of the set. Now given a graph with several vertex sets, you are supposed to tell if each of them is a vertex cover or not. Input Specif

One way that the police finds the head of a gang is to check people's phone calls. If there is a phone call between A and B, we say that A and B is related. The weight of a relation is defined to be the total time length of all the phone calls made b

A graph which is connected and acyclic can be considered a tree. The hight of the tree depends on the selected root. Now you are supposed to find the root that results in a highest tree. Such a root is called the deepest root. Input Specification: Ea

使用python的图形库. 环境:conda+jupyter notebook 代码如下: import numpy as np from PIL import Image from numba import jit MAXITERS = 200 RADIUS = 100 @jit def color(z, i): v = np.log2(i+1-np.log2(np.log2(abs(z))))/5 if v < 1.0: return v**4, v**2.5, v else: v = ma

UITableView可以算是使用频率最高的组件之一的,在开发过程中经常需要展示一些简单的信息列表常见列表布局 如图,很多页面其实就是这种展示结果,通常需要imageView,textLabel,detailTextlabel,而UITableViewCell本身提供了方便的自动布局(当有图片和没图片时,textLabel和detailLabel的位置会左右自动调整). 但是图片的大小却是没有办法固定的(直接设置imageView.frame是无法固定imageView的大小的),那么一般来说解
