如何在日历热图上使用黑白填充图案而不是颜色编码 [英] how to use black-and-white fill patterns instead of color coding on Calendar Heatmap
问题描述
我使用类似于 this plot 。
在他成为赏金之前，我回答了这个问题。它看起来像OP找到我以前的答案有点复杂。我在一个要点此处中组织代码。你需要下载文件并获取它。
我创建了一个新函数 extra.calendarHeat ，它是一个扩展第一个绘制双时间序列的hetmap。（dat，value1，value2）。我添加了这个新参数：
pch.symbol：符号向量，默认值15:20
cex.symbol：cex的符号，默认= 2
col.symbol：符号的颜色，默认＃00000044
pvalues：符号的值
这里有一些例子：
##我使用相同的数据
stock < - MSFT
start.date< - 2012-01-12
end.date< - Sys.Date（）
quote< - paste（http ：//ichart.finance.yahoo.com/table.csv？s =，
股票，
& a =，substr（start.date，6,7），
& b =，substr（start.date，9,10），
& c =，substr（start.date，1,4），
& d = ，substr（end.date，6,7），
& e =，substr（end.date，9,10），
& f =，substr（end。日期，1,4），
& g = d& ignore = .csv，sep =）
stock.data< - read.csv（quote，as.is = TRUE ）
p1 < - extra.calendarHeat（dates = stock.data $ Date，values = stock.data $ Adj.Close，
pvalues = stock.data $ Volume，
）b
$ b
##乘以符号
p2 < - extra.calendarHeat（dates = stock.data $ Date，values = stock.data $ Adj.Close，
pvalues = stock.data $音量，
varname =W& B MSFT调整关闭\
黑色音量作为乘法符号，
pch.symbol = c（3,4,8,9），
col.symbol ='black'）
##圆圈符号
p3 < - extra.calendarHeat（dates = stock.data $ Date，values = stock.data $ Adj.Close，
pvalues = stock.data $ Volume，
varname =W& B MSFT Adjusted Close \\\
blue Volume as circles，
pch.symbol = c（1,10,13,16， 18），
col.symbol ='blue'）
##三角形符号
p4 < - extra.calendarHeat（dates = stock.data $ Date，values = stock.data $ Adj.Close，
pvalues = stock.data $ Volume，
varname = W& B MSFT调整关闭\红色音量为三角形，
pch.symbol = c（2,6,17,24,25），
col.symbol ='red'）
p5 < - extra.calendarHeat（dates = stock.data $ Date ，values = stock.data $ Adj.Close，
varname =MSFT Adjusted Close，
pch.symbol = LETTERS，
col.symbol ='black'）
＃符号为字母
p6 < - extra.calendarHeat（dates = stock.data $ Date，values = stock.data $ Adj.Close，
pvalues = stock.data $ Volume，
varname =MSFT Adjusted Close \\\
Volume as LETTERS symbols，
pch.symbol =字母，
color ='r2b'）
I'm using Paul Bleicher's Calendar Heatmap to visualize some events over time and I'm interested to add black-and-white fill patterns instead of (or on top of) the color coding to increase the readability of the Calendar Heatmap when printed in black and white.
Here is an example of the Calendar Heatmap look in color,
and here is how it look in black and white,
it gets very difficult to distinguish between the individual levels in black and white.
Is there an easy way to get R to add some kind of patten to the 6 levels instead of color?
Code to reproduce the Calendar Heatmap in color.
source("http://blog.revolution-computing.com/downloads/calendarHeat.R")
stock <- "MSFT"
start.date <- "2012-01-12"
end.date <- Sys.Date()
quote <- paste("http://ichart.finance.yahoo.com/table.csv?s=", stock, "&a=", substr(start.date,6,7), "&b=", substr(start.date, 9, 10), "&c=", substr(start.date, 1,4), "&d=", substr(end.date,6,7), "&e=", substr(end.date, 9, 10), "&f=", substr(end.date, 1,4), "&g=d&ignore=.csv", sep="")
stock.data <- read.csv(quote, as.is=TRUE)
# convert the continuous var to a categorical var
stock.data$by <- cut(stock.data$Adj.Close, b = 6, labels = F)
calendarHeat(stock.data$Date, stock.data$by, varname="MSFT Adjusted Close")
update 02-13-2013 03:52:11Z, what do I mean by adding a pattern,
I envision adding a pattern to the individual day-boxes in the Calendar Heatmap as pattern is added to the individual slices in the pie chart to the right (B) in this plot,
found here something like the states in this plot.
解决方案 I answered this question before he becomes a bounty. It looks like the OP find my previous answer a little bit complicated. I organized the code in a single gist here. you need just to download the file and source it.
I create new function extra.calendarHeat which is an extension of the first one to draw hetmap of double time series.(dat,value1,value2). I addedthis new parameters:
pch.symbol : vector of symbols , defualt 15:20
cex.symbol : cex of the symbols , default = 2
col.symbol : color of symbols , default #00000044
pvalues : value of symbols
Here some examples:
## I am using same data
stock <- "MSFT"
start.date <- "2012-01-12"
end.date <- Sys.Date()
quote <- paste("http://ichart.finance.yahoo.com/table.csv?s=",
stock,
"&a=", substr(start.date,6,7),
"&b=", substr(start.date, 9, 10),
"&c=", substr(start.date, 1,4),
"&d=", substr(end.date,6,7),
"&e=", substr(end.date, 9, 10),
"&f=", substr(end.date, 1,4),
"&g=d&ignore=.csv", sep="")
stock.data <- read.csv(quote, as.is=TRUE)
p1 <- extra.calendarHeat(dates= stock.data$Date, values = stock.data$Adj.Close,
pvalues = stock.data$Volume,
varname="W&B MSFT Adjusted Close
\n Volume as no border symbol ")
## multiply symbols
p2 <- extra.calendarHeat(dates= stock.data$Date, values = stock.data$Adj.Close,
pvalues = stock.data$Volume,
varname="W&B MSFT Adjusted Close \n
black Volume as multiply symbol ",
pch.symbol = c(3,4,8,9),
col.symbol='black')
## circles symbols
p3 <- extra.calendarHeat(dates= stock.data$Date, values = stock.data$Adj.Close,
pvalues = stock.data$Volume,
varname="W&B MSFT Adjusted Close \n blue Volume as circles",
pch.symbol = c(1,10,13,16,18),
col.symbol='blue')
## triangles symbols
p4 <- extra.calendarHeat(dates= stock.data$Date, values = stock.data$Adj.Close,
pvalues = stock.data$Volume,
varname="W&B MSFT Adjusted Close \n red Volume as triangles",
pch.symbol = c(2,6,17,24,25),
col.symbol='red')
p5 <- extra.calendarHeat(dates= stock.data$Date, values = stock.data$Adj.Close,
varname="MSFT Adjusted Close",
pch.symbol = LETTERS,
col.symbol='black')
# symbols are LETTERS
p6 <- extra.calendarHeat(dates= stock.data$Date, values = stock.data$Adj.Close,
pvalues = stock.data$Volume,
varname="MSFT Adjusted Close \n Volume as LETTERS symbols",
pch.symbol = letters,
color='r2b')
