bar-chart

问题 I have data with one observation per row: rm(list = ls(all = TRUE)) mydf <- data.frame(kind = sample(c("good", "bad"), 100, replace = TRUE), var1 = sample(c("yes", "no", "yes"), 100, replace = TRUE), var2 = sample(c("yes", "no"), 100, replace = TRUE), var3 = sample(c( "yes", "no"), 100, replace = TRUE), var4 = sample(c( "yes", "no", "yes", "no", "NA"), 100, replace = TRUE), var5 = sample(c( "yes", "no", "yes", "no", "NA"), 100, replace = TRUE), var6 = sample(c( "yes", "no", "yes", "no", "NA")

问题 I'm having a really hard time trying to figure out how to make a stacked bar chart in R. First of all, the data I'm working with is from the VCD package data("Arthritis", package = "vcd") Now, I only want to graph the columns Improved and Treatment , displaying two bars which are the two results of the Treatment column (Treated, Placebo) and have the results of the Improved column stacked on top of each other. I tried some commands but it kept giving me an error saying: 'height' must be a

问题 I am looking to develop an animated/growing bar plot.The plot basically contains of 6 rectangular bars and each bar has a particular value. The problem I'm facing is that the plot is growing up to the maximum value on Y-axis instead it should stop at the bar's corresponding value. The code I have tried makes the bars animate up to the maximum value on Y-Axis.I have found some information from Growing matplotlib bar charts import numpy as np import matplotlib.pyplot as plt from matplotlib

问题 In my plot, I'm trying to display the average delay time from 6 airports for each of the 5 dates. Here is the code I have so far: F = dataset('xlsfile','Lab2_Delta'); DATES = {'11/26/2013','11/27/2013','11/28/20113','11/29/2013','11/30/2013'}; ORIGINS = {'CVG','ORD','ATL','LAX','MIA','DFW'}; for Index = 1:6 for Index2 = 1:5 Origin_Index = find(strcmp(F.Origin,ORIGINS(Index))); Date_Index = find(strcmp(F.Date,DATES(Index2))); Temps(Index2,Index) = mean(F.Delay(Date_Index)); end end bar(1:5

问题 As the title says, I would like to add ticks to the TOP part of the bar plot in ggplot2. The output would look something like this: (hiding the actual plot due to confidential information). Is there a function in ggplot2 that does this? 回答1: I have adapted Baptiste's solution at link Display y-axis for each subplot when faceting. Idea (i think) is to extract the x-axis grob and add it to the top of the plot. library(ggplot2) library(gtable) # plot p1 <- ggplot(mtcars, aes(factor(cyl))) + geom

问题 I'm wondering if it is possible to get the same grouping behavior of bar plots into bar3 . For example, if you plot bar(rand(3)); you get 3 bars for each point; bar groups the different y values for each x . Now I would like to do the same with a 3D data. That is that I have several slices of 2D data that I want to visualize as groups of bars. Then, if my data is data = rand(3,3,2); I would like to see data(1,1,:) as a group of bars, and data(1,2,:) as another group and so on. Is it possible?

问题 I'm using FPDF in my php project. I would like to have PDF version Double bar diagram like above image in my project. There's a way that FPDF can create Pie chart and Bar diagram in http://www.fpdf.org/en/script/script28.php. But it's not double bar diagram like what I want to get. Anyone have an idea how to create Double bar diagram using FPDF in PHP? Many Thanks !!! 回答1: Probably you mean "COLUMN CHARTS" It seems that there is no method to create column charts, so I tried to adapt the

问题 I generate a barplot with geom_col() with two classes separated by color. Then I try to add a mean line for each class. Here is what I'd like to get: But with the code below the mean line is for each bar independently what I put to group argument. Here is a reproducible example: library(tidyverse) df = data.frame( x = 1:10, y = runif(10), class = sample(c("a","b"),10, replace=T) %>% factor() ) %>% mutate(x = factor(x, levels=x[order(class, -y)])) ggplot(df, aes(x, y, fill=class)) + geom_col()
