Below is a plot that I want to include in a paper. The problem is the width of my plot which is to small (that make x-axix not readable at all)
Here is the ggplot2 code myCode.r :
require("ggplot2") all <- read.csv(file="benchmark/bench.query.csv", head=TRUE, sep=";") w <- subset(all, query %in% c("sort.q1", "sort.q2", "sort.q3", "sort.q4", "sort.q5")) w$rtime <- as.numeric(sub(",", ".", w$rtime, fixed=TRUE)) p <- ggplot(data=w, aes(x=query, y=rtime, colour=triplestore, shape=triplestore)) p <- p + scale_shape_manual(values = 0:length(unique(w$triplestore))) p <- p + geom_point(size=4) p <- p + geom_line(size=1,aes(group=triplestore)) p <- p + labs(x = "Requêtes", y = "Temps d'exécution (log10(ms))") p <- p + scale_fill_continuous(guide = guide_legend(title = NULL)) p <- p + facet_grid(trace~type) p <- p + theme_bw() ggsave(file="bench_query_sort.pdf") print (p) I've look around to see how to enlarge the plot, but I found nothing.
Any idea about what to add/delete/modify in my code ?

If we want to control the width of our line graphic, we have to specify the size argument within the geom_line function. Have a look at the following R code and the resulting image: Figure 2: ggplot2 Line Graph with Thick Line. As you can see, the previous R syntax increased the size of the lines of our plot.
The following code shows how to make the points in our ggplot2 scatterplot larger. For this, we have to specify a large value to the size argument within the geom_point function. Have a look at the following example code: ggplot (data, aes (x, y)) + # Increase point size geom_point (size = 10)
Our example data consists of ten rows and the two columns x and y. Furthermore, we need to install and load the ggplot2 package to RStudio: Now, we can draw a line plot with default specifications as follows: ggplot ( data, aes ( x, y)) + # Create default line plot geom_line () Figure 1: Default ggplot2 Line Graph.
BarPlot using ggplot2 in R To Increase or Decrease width of Bars of BarPlot, we simply assign one more width parameter to geom_bar () function. We can give values from 0.00 to 1.00 as per our requirements.
Inside a Jupyter notebook I found the following helpful:
# Make plots wider options(repr.plot.width=15, repr.plot.height=8) Probably the easiest way to do this, is by using the graphics devices (png, jpeg, bmp, tiff). You can set the exact width and height of an image as follows:
png(filename="bench_query_sort.png", width=600, height=600) ggplot(data=w, aes(x=query, y=rtime, colour=triplestore, shape=triplestore)) + scale_shape_manual(values = 0:length(unique(w$triplestore))) + geom_point(size=4) + geom_line(size=1,aes(group=triplestore)) + labs(x = "Requêtes", y = "Temps d'exécution (log10(ms))") + scale_fill_continuous(guide = guide_legend(title = NULL)) + facet_grid(trace~type) + theme_bw() dev.off() The width and height are in pixels. This is especailly useful when preparing images for publishing on the internet. For more info, see the help-page with ?png.
Alternatively, you can also use ggsave to get the exact dimensions you want. You can set the dimensions with:
ggsave(file="bench_query_sort.pdf", width=4, height=4, dpi=300) The width and height are in inches, with dpi you can set the quality of the image.
