Apply lines() to columns of a data frame/matrix; each line with a different color

前提是你 提交于 2020-01-02 06:15:47
问题 I am trying to come up with a solution that doesn't involve using other packages such as ggplot. While plotting multiple lines is pretty straightforward, I haven't figured out a way to apply different values of an argument - e.g., different colors - to different lines. The code below (with the resulting plot) was my attempt, which obviously didn't do what I would like it to do. I also don't want to use a loop because I am trying to make my script as simple as possible. df = cbind(sort(rnorm

Creating line dividers in Android tab layout paragraphs

你离开我真会死。 提交于 2020-01-02 05:18:08
问题 Hey all, first post and a noob in Android programming, but willing to learn! Basically I've taken the Google sample of a tab layout from here I found that method to be very easy to create tabs with text within each tab, but I'm trying to make it so that when a tab is selected, I want the text listed below to be separated by a dividing line. So that a line is dividing between each paragraph, however I'm having trouble doing this. This is what I have so far: main.xml: <?xml version="1.0"

Getting new position of a line after rotation

穿精又带淫゛_ 提交于 2020-01-02 05:06:06
问题 I need to find out new coordinates of line after rotation using RotateTransform method on a line. For example, after this line: line.RenderTransform = new RotateTransform(25, 0, 0); line.X1 and the three other properties don't change. I have found some solution for shapes like rectangular, but it doesn't work for line. Line has different way how to treat with it. EDIT: Thanks for your help H.B. The second way is exactly what I've been looking for. SOLUTION: Line line = new Line(); line.X1 =

Shorten command line for Application or also for Spring Boot default configuration. 错误翻译: 命令行太长。缩短应用程序或Spring启动默认配置的命令行。 之所以出现这个原因是一般是因为打印的环境变量太长了,超过了限制。 解决方法: 一: 在.idea 文件夹中打开 workspace.xml 文件找到 <component name="PropertiesComponent"> ,然后在该标签里加一行 <property name="dynamic.classpath" value="true" /> 修改idea的安装配置文件来达到目的 意思是: 在属性组件中打开动态的类路径 二: 按照提示修改该类的配置,选择jar manifest(每个报错的类都需要注意设置,项目的.idea/workspace

pattern for saving newline-delimited json aka linejson aka jsonlines with python

核能气质少年 提交于 2020-01-02 04:11:08
问题 With Python, I'm saving json documents onto separate lines like this: from bson import json_util # pymongo with open('test.json', 'ab') as f: for document in documents: f.write(json_util.dumps(document)+'\n') and then reading like this: with open('test.json') as f: for line in f: document = json_util.loads(line) The ease and simplicity make me think that there must be a gotcha? Is this all there is to linejson, aka jsonlines? 回答1: Yes, that's all there is to it. 来源: https://stackoverflow.com

关于python中的enumerate函数的应用

≡放荡痞女 提交于 2020-01-02 01:41:29
在python中的enumerate函数是用来遍历列表 用法如下: lst = [1,2,3] for index,item in enumerate(lst ): print '%d : %s' % (index,item) 这里index对应的是列表lst 中的序号,而item则对应列表lst 中的元数。 另外: python enumerate 用法 | 在for循环中得到计数 参数为可遍历的变量,如 字符串,列表等; 返回值为enumerate类: import string s = string.ascii_lowercase e = enumerate(s) print s print list(e) 输出为: abcdefghij [(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd'), (4, 'e'), (5, 'f'), (6, 'g'), (7, 'h'), (8, 'i'), (9, 'j')] 在同时需要index和value值的时候可以使用 enumerate。 enumerate 实战 line 是个 string 包含 0 和 1,要把1都找出来: #方法一 def read_line(line): sample = {} n = len(line) for i in range(n): if line[i]!='0':

How can I draw a straight line in the JMonkey Engine library

我只是一个虾纸丫 提交于 2020-01-01 16:48:35
问题 I'm trying to draw straight lines between 3D vertices that I specify using the JMonkey Engine 3D graphics library. JMonkey is of course optimised for importing models but I understand it can be used to create custom shapes "internally" as well. So for example if I was to try to plot between: (2,0,0) (-1,0,1) (0,1,1) (1,1,1) (1,4,0) Then I would get: 回答1: Update In the most recent version of Jmonkey a Line class exists which makes this process far simpler. This is detailed here. Original

linux shell 之在线文本编辑sed

百般思念 提交于 2020-01-01 13:36:36
sed命令 sed是一种文本编辑命令,读取文件数据到缓冲区,然后通过sed编辑文本,在输出到指定的文件,sed 是一种流编辑器,它是文本处理中非常中的工具,能够完美的配合正则表达式使用,sed按行处理文本数据,不断重复,直到文件末尾。可同时处理多个文件; 先讲个实例,大家看到如下一堆字符串,这是有多个sed命令表达式组合成的命令,|表示多个表达式的组合,\表示换行,冒号中s表示替换,g表示全部替换;$0是第一个输入参数,是一个文件名称,第一行意思是读取文件中的数据,将IVMS_SERVICE=0全部替换成IVMS_SERVICE=1,这里只是字符替换;第二行是将变量$SVC_PROG全部替换掉IVMS_SERVICE_PROG,第四行是先替换,然后将缓冲区中的数据输入到变量$SVC_SYS_FILE标记的文件中; # create service bash sed -e "s%IVMS_SERVICE=0%IVMS_SERVICE=1%g" $0 | \ sed -e "s%IVMS_SERVICE_PROG%$SVC_PROG%g" | \ sed -e "s%IVMS_SERVICE_NAME%$SVC_NAME%g" | \ sed -e "s%IVMS_SERVICE_DIR%$SVC_DIR%g" > $SVC_SYS_FILE sed的选项、命令、替换标记 命令格式
