Simple python for adding jitter to a list of values to help plotting beeswarm/jitter plots
The first few lines of the file test.dat looks like this
f99y 10 1.884 0.000 -0.909 0.000 2.793 0.000 102.485 0.000
f99y 10 1.466 0.000 -1.066 0.000 2.533 0.000 67.124 0.000
f99y 10 0.885 0.000 -1.412 0.000 2.296 0.000 45.752 0.000
f99y 10 1.915 0.000 -1.028 0.000 2.943 0.000 130.686 0.000
Let's say we want to plot column 2 (remember is 0-based). If you do this naively, many of the points will lie on top of one another.
To see where they all are, we can add some jitter.
./jitter.py --filename test.dat --column 2 --x_step 0.2 --y_step 0.2 --x_centre 0.0 > jittered.dat
Now the graph looks something like this.
If you play around with the x_step and y_step values and pointsize you can pack the points closer together. And, yes, I know MatPlotLib and Seaborn etc can do this. I wanted something I could use with gnuplot v4.6 (not 5).
