bar-chart

问题 I would like to use Greek characters, Latin characters and the percent sign in the facet labels of a ggplot2 bar chart. Greek characters can be done with 'facet_grid(.~variable, labeller=label_parsed)': a<-c("Delta~V","VarcoV","Delta~V","VarcoV") b<-c(1,2,3,4) d<-c("one","one","two","two") mydata<-data.frame(cbind(b,a,d)) ggplot(mydata,aes(x=d,y=b))+facet_grid(.~a, labeller=label_parsed)+geom_bar(stat="identity") Now I also want to add a facet label that includes % and a Latin character: a<-c

问题 This question already has answers here : R stacked percentage bar plot with percentage of binary factor and labels (with ggplot) (1 answer) geom_text position middle on a bar plot (1 answer) Closed 2 years ago . I want to plot a table as a stacked bar plot and label the bars with the percentages. Here is an example: data <- matrix(c(34, 66, 22, 78), ncol = 2) data <- as.table(data) colnames(data) <- c("shop1", "shop2") rownames(data) <- c("prod1", "prod2") library(reshape2) data_m <- melt

问题 with a data frame of 3 columns, i would like to assign the colour "red" to values below 19.293 and "blue" to values above 19.293. dataframe123 <- data.frame(hmin1, hmin2, hmin3) The following are the values in the data frame hmin1: c(3.93999999999999, 6.13333333333333, 8.12727272727273, 9.94782608695652, 11.6166666666667, 13.152, 14.5692307692308, 15.8814814814815, 17.1, 18.2344827586207, 19.2933333333333, 20.2838709677419, 21.2125, 22.0848484848485, 22.9058823529412, 23.68, 24.4111111111111,

问题 I have some data with mixed positive and negative values that the sum of the absolute values of each variable = 100% Here are some sample data: Out01 = [79.069,-1.602,5.067,-4.241,-5.433,-4.590] Out02 = [50.348,13.944,-15.373,6.554,5.541,8.240] Out03 = [-8.053,0.819,-9.741,2.814,22.475,56.098] Out04 = [-17.350,33.710,-18.510,-0.842,3.050,26.537] Out05 = [-20.169,37.583,-20.785,-2.041,1.728,17.695] I drew them as desired in Microsoft Excel as follows by the "100% stacked columns" chart: Now I

问题 I would like to reduce bar gap and keep bar width of stacked bar plot. Stacked bar plot: p <- ggplot(dat, aes(x = plant, y = percentage*100, fill = group)) + geom_bar(stat = "identity", width =0.20) and then I want to change bar gaps by position=position_dodge(0.9) : p <- ggplot(dat, aes(x = plant, y = percentage*100, fill = group)) + geom_bar(stat = "identity", position=position_dodge(0.9),width =0.20) This solution can change bar gaps, but bars were unstacked. So how to change bar gap and

问题 I have two sets of values that are linearly dependent. Therefore I just need a single graph with a second y-axis in the right scale. What is the most elegant way to do this? Making just two bar-plots gives me an overlap: import numpy as np import matplotlib.pyplot as plt x = np.arange(4) y2 = np.array([23, 32, 24, 28]) y1 = 4.2 * y2 fig = plt.figure(1, figsize=(6,6)) ax = fig.add_subplot(111) ax.bar(x, y2) ax.set_ylabel('Consumption in $m^3$') ax2 = ax.twinx() ax2.bar(x, y1, alpha=0.5) ax2

问题 I want to draw a bar with error bounds like this http://www.mathworks.ch/matlabcentral/fileexchange/9377-barerror. There are many scripts to do this around that combine bar() and errorbar(). But all I found can only deal with symmetric errors. Can anyone show me how to add asymmetric error bounds like errorbar(X,Y,L,U) but on bar, not on curve? Thanks. 回答1: You can plot errorbars over your bar chart: data = 1:10; eH = rand(10,1); eL = rand(10,1); figure; hold all; bar(1:10, data) errorbar(1
