It can be used only when pch = 21:25. cex: the size of pch symbols; lwd: the line width for the plotting symbols # Change color plot(x, y, pch=19, col="darkgreen", cex=1.5) # Color can be a vector plot(x, y, pch=19, … key.length: amount of space reserved for the key along its axis, length of the scale bar. The “size” function is not affecting the plot output size, in: using PyPlot x = [1,2] y = x plot(x,y) size(10,200) savefig("./test.png") I tried also savefig("./test.png",figsize=(10,200)) or savefig("./test.png",width=10,height=200) Without any result either. cols: Deprecated.

Note that greater values will display larger texts. labels), thickness/width of the scale bar. cex: numeric values indicating the point size. Now, anybody who has used R has at some point asked the question "How to save a plot as image on the disk?". Conversely, any value of cex greater than 1 can increase the font size. You may change this value to whatever value you want. Use special pch types, including pch 21 and pch 24.

Auto select depends on plot size, map aspect, and, if set, parameter asp. For this R ggplot2 Dot Plot demonstration, we use the airquality data set provided by the R.

The R Scatter plot displays data as a collection of points that shows the linear relation between those two data sets. Some viewers may render some plots in that colorspace faster than in sRGB, and the plot files will be smaller. This will be helpful when we want to express X-axis or Y-axis differently.
