As follows: pets_df % add_column(pet = 'cat'), Plot <- ggplot(data =, aes(x = Breed, y = Longevity, fill = Breed)) +Īn alternative to the list approach mentioned in the other answers would be to first have everything in the same ame, since apparently all the tables have the same variables and then have one more variable indicating what kind of pet does the observation correspond to. Panel.background = element_rect(fill = NA), text = element_text(size=10)) Panel.border = element_rect(color = "black", fill = NA, size = 0.8), Legend.position = "none", plot.title = element_text(hjust =. Theme(axis.line = element_line(color = "black"), axis.text = element_text(color = "black"), Geom_text(aes(label = Longevity), vjust = -0.3, color = "black", size = 3.5) + Geom_bar(stat = "identity", position = position_dodge()) + Plot <- ggplot(data = cat, aes(x = Breed, y = Longevity, fill = Breed)) + #etc for types of birds, fish, snakes, and ferrets cat <- ame(Breed = c("American Shorthair","Ragdoll","Persian","Sphynx","Maine Coon"),ĭog <- ame(Breed = c("Havanese","Bulldog","Beagle","Chihuahua","Poodle"), My six dataframes are the six animals listed in gg_pets.
#Gnuplot for loop code
My code works when I run the plots separately but I can't get ggplot to run six times using a for loop. Which will plot the second column versus the first column of 'file_1.dat' through 'file_10.dat'.I want to run through six similar dataframes and print out six plots using ggplot. Plot for filename(i) using 1:2 with lines The second option is, if the data files are numbered, e.g., if we have 'file_1.dat', 'file_2.dat', and so on, we can use the iteration over integers as follows E.g., if we wanted to, instead of 'first', 'second', etc., plot 'first.dat', 'second.dat', and so on, we would do this as
At this point, note that 'file' is a string, i.e., we can manipulate it as a string. Which will plot files 'first', 'second', 'third', 'fourth', and 'fifth'. One is that we simply specify the file names in a string, as belowįilenames = "first second third fourth fifth" When doing so, there are two options available. We can also use the iteration to plot different files. This was an example, when we plot various columns from the same file.
The importance of this is that many plot styles require several columns, and we could not use those plot styles with functions without the '+' pseudo-file. I.e., we can specify 'using' for a function. This was introduced in gnuplot 4.4, and the purpose of this special file is that by invoking this, one can use the standard plot modifiers even with functions. Note, however, that we do this by plotting a special file, '+'. We then plot this function to a file, 'iter.dat', and do it 6 times, and each time with a different parameter, so that the Gaussian is shifted, and becomes broadened. So, after re-setting the gnuplot session, we define a function, which will be a Gaussian, whose centre and width is determined by the parameter 'a'. I would like to walk through the script line by line, for there is something unusual in almost each line. Plot for 'iter.dat' u 0:(column(i)+2*i) w l lw 1.5 t title(i)
This is common practice, when one has several spectra, and wants to show the effect of some parameter on the spectra.į(x,a) = exp(-(x-a)*(x-a)/(1+a*0.5))+0.05*rand(0) The first example that I will show is that of waterfall plots, i.e., when a couple of curves are plotted on the same graph, and they are shifted vertically. Plot for Īfter this introduction, let us see how these can be used in real life. There are forms of it: once one can loop through integers, while in the other case, one can step through a string of words. If you have ever had to script the creation of your plots, you will appreciate these features.įirst, let us see what the for loop looks like in the plot command. The first one that I would like to show is the concept of iteration in the plot command, and the concept of certain pseudo-files. As I promised some time ago, I will discuss some of the new features in gnuplot 4.4.
