I plot the following: library(ggplot2) carrots <- data.frame(length = rnorm(500000, 10000, 10000)) cukes <- data.frame(length = rnorm(50000, 10000, 20000)) carrots$veg <- ‘carrot’ cukes$veg <- ‘cuke’ vegLengths <- rbind(carrots, cukes) ggplot(vegLengths, aes(length, fill = veg)) + geom_density(alpha = 0.2) Now say, I only want to plot the region between x=-5000 to 5000, instead of the entire … Read more
I have a semilogx plot and I would like to remove the xticks. I tried: plt.gca().set_xticks([]) plt.xticks([]) ax.set_xticks([]) The grid disappears (ok), but small ticks (at the place of the main ticks) remain. How to remove them? 10 Answers 10
I have the following plot like below. It was created with this command: library(ggplot2) df <- data.frame(cond = factor(rep(c(“A”, “B”), each = 200)), rating = c(rnorm(200), rnorm(200, mean=.8))) ggplot(df, aes(x=rating, fill=cond)) + geom_density(alpha = .3) + xlab(“NEW RATING TITLE”) + ylab(“NEW DENSITY TITLE”) Now, I want to modify the legend title from cond into NEW … Read more
I’m trying to plot a figure without tickmarks or numbers on either of the axes (I use axes in the traditional sense, not the matplotlib nomenclature!). An issue I have come across is where matplotlib adjusts the x(y)ticklabels by subtracting a value N, then adds N at the end of the axis. This may be … Read more
I would like to plot y1 and y2 in the same plot. x <- seq(-2, 2, 0.05) y1 <- pnorm(x) y2 <- pnorm(x, 1, 1) plot(x, y1, type = “l”, col = “red”) plot(x, y2, type = “l”, col = “green”) But when I do it like this, they are not plotted in the same … Read more
I am trying to fix how python plots my data. Say x = [0,5,9,10,15] and y = [0,1,2,3,4] Then I would do: matplotlib.pyplot.plot(x,y) matplotlib.pyplot.show() and the x axis’ ticks are plotted in intervals of 5. Is there a way to make it show intervals of 1? 13 s 13 You could explicitly set where you … Read more
Matplotlib offers these functions: cla() # Clear axis clf() # Clear figure close() # Close a figure window When should I use each function and what exactly does it do? 3 s 3
Apparently, folk have figured out how to make xkcd style graphs in Mathematica and in LaTeX. Can we do it in R? Ggplot2-ers? A geom_xkcd and/or theme_xkcd? I guess in base graphics, par(xkcd=TRUE)? How do I do it? As a first stab (and as much more elegantly shown below) in ggplot2, adding the jitter argument … Read more
How do I change the size of figure drawn with Matplotlib? 25 s 25 figure tells you the call signature: from matplotlib.pyplot import figure figure(figsize=(8, 6), dpi=80) figure(figsize=(1,1)) would create an inch-by-inch image, which would be 80-by-80 pixels unless you also give a different dpi argument.
I am writing a quick-and-dirty script to generate plots on the fly. I am using the code below (from Matplotlib documentation) as a starting point: from pylab import figure, axes, pie, title, show # Make a square figure and axes figure(1, figsize=(6, 6)) ax = axes([0.1, 0.1, 0.8, 0.8]) labels=”Frogs”, ‘Hogs’, ‘Dogs’, ‘Logs’ fracs = … Read more
