legend

问题 I am plotting a series of lines using ggplot and shading between them. There are 10 lines, but only 5 shaded regions. I want the legend for the 5 shaded regions. At the moment no legend is showing. I thought the line scale_color_manual(name="test",labels = c("90%","70%","50%","30%","10%"), values = c("Darkolivegreen1", "Darkolivegreen2","Darkolivegreen3","Darkolivegreen4","Darkolivegreen")) would add a manual colour bar with the shaded region, but nothing shows. The full plot code is below.

问题 I have a table that looks like this: ID Survival Event Allele 2 5 1 WildType 2 0 1 WildType 3 3 1 WildType 4 38 0 Variant I want to do a kaplan meier plot, and tell me if wild type or variants tend to survive longer. I have this code: library(survival) Table <-read.table("Table1",header=T) fit=survfit(Surv(Table$Survival,Table$Event)~Table$Allele) plot(fit,lty=2:3,col=3:4) From the fit p value, I can see that the survival of these two groups have significantly different survival curves.

问题 I'm trying to replicate the following plot: Plot to replicate I have gotten as far as this: My plot Hence, the only thing left to do is change the symbols in the legend to big round circles instead of small circles with a line going through them. How can I achieve this without making the circles in my plot bigger? I used the following code to create my plot so far: g <- ggplot(d, aes(x = Num.3.Syllable.Words / Num.Words, y = Num.Words / Num.Sentences, colour = Educational.Level)) g + geom

问题 I am trying to tweak a few thematic elements in a ggplot2 figure. My three questions/goals for this multi-layered figure are (code for data follows at end): Create a x-axis tick mark label for all eight year, i.e., 2004-2011. I do not want a 'xlab' though. Remove the two filled dots from the "Infected Stems" legend b/c these "geom_bars" should not have dots associated with them (???). Change the Legend Title for the lines/points legend to "SOD-dead Stems". My code is probably redundant to

问题 How to change the vertical space between series titles. Is it possible to separate the series titles into two groups and have a gap between them, like this one: Thanks. 回答1: You can insert some kind of 'dummy' plot where you want to have the white space: set xrange [0:4] set key left plot x, \ 2*x t '2x', \ NaN title ' ' lt -3,\ 3*x t '3x',\ 4*x t '4x' The special linetype -3 doesn't draw any line at all, using linewidth 0 wouldn't work for all terminals (e.g. postscript). And the title must

问题 I'm working with a pretty simple example. I create three scatter plots on the same set of axes, and each data set I plot has a different associated colormap. However, the legend does not look as I'd want it to; why is this? import numpy as np import matplotlib.pyplot as plt t = np.linspace(0,10,100) x = np.random.rand(100,3) y = np.random.rand(100,3) colmaps = ['Blues', 'Greys', 'Reds'] for i in range(3): plt.scatter(x[:,i], y[:,i], c=t, cmap=colmaps[i], label=i) plt.legend() plt.show() This

问题 I'm trying to generate a beautiful legend in R plots. I have a factor=1e-5 , that should appear nicely formatted in the legend. I found a nice function in the package sfsmisc , that transforms numbers to expressions. To add this expression to my bquote command, it seems that I need to transform itto a call. unfortunately, there are braces added at the end of the string ( 10^-5() ). Is there a way to avoid the addition of thoses braces? Or is there even an easier way to transform numbers to
