Adding text labels to ggplot2, Is it possible to add text labels to a bar chart in a simple way? Yes, In this article, you’ll learn how to add a frequency count to each bar in a bar chart. First, let’s make a data frame. Animated Graph GIF with gganimate & ggplot » Addi...
library(ggplot2) library(directlabels) df <- expand.grid(x=1:100, y=1:100) df$z <- df$x * df$y p <- ggplot(aes(x=x, y=y, z=z), data = df) + geom_raster(data=df, aes(fill=z), show.legend = TRUE) + scale_fill_gradient(limits=range(df$z), high = 'white', low...
and a working post-hov script - now I just need them all to play together nicely. The issue I am facing is that the Tukey HSD group labels do not line up with the graphic's bars (ie. the output order does not correspond to the graphical order) and they are not centered. See the...
One of the small problems I faced was adding labels to pictures. You know — like A, B, C… in the top right corner of each panel of a composite figure. Here is the output I was striving at: Doing it proved to be more tedious than I thought at first. By default,...
Finally, we are going to put labels to the lines in order to know what are their meaning. ggplot(bit_2017,aes(x=Date,y=Close))+geom_line(color="blue")+geom_line(aes(y=mean(Close)),color="red",linetype="dotted")+geom_line(aes(y=quantile(Close,0.75)),color="black",linetype="...
p <- ggplot(datapoly, aes(x=x, y=y)) + geom_polygon(aes(fill=id, group=id)) + scale_fill_manual(values = c("gray", "yellow", "orange", "red", "darkred", "#90C3D4"), name = "IPC Phase of Acute Food Insecurity", labels = c("1: None or Minimal", "2: Stressed",...
One potential solution to your problem is to plot "Type" on the x axis instead of "x", e.g. data %>% ggplot(aes(x = Type, y = ratio)) + geom_col(aes(fill = `Sample Selection`), position = position_dodge(preserve = "single"), na.rm = TRUE) + geom_t...
ggplot()+geom_bar(aes(fill=columns,y=diffs,x=samps),stat="identity",position="fill")+scale_fill_discrete(name="Preprocessing Steps",labels=labels,# Order set to 1 to appear before dotguide=guide_legend(order=1))+theme(axis.text.x=element_text(angle=90,hjust=1))+xlab("Samples")+ylab...
e.g a table of labels to tile the panel with multiple repetitions of the watermark, or an external graphic (consider theannotation_rasterfunction), etc. As an example, the following function usesrpatternGrobfrom the gridExtra package to tile multiple copies of the R logo, imported as a raste...
removeGrid- Remove grid lines from ggplot2. Minor grid lines are always removed, and the major x or y grid lines can be removed as well. rotateTextX- Rotate x axis labels. Often times it is useful to rotate the x axis labels to be vertical if there are too many labels and they ove...
