Gnuplot

numpy

Installation:

pip install PyGnuplot
  • Upgrade:
pip install --upgrade  PyGnuplot

Functions:

c(command)

pipe a command to gnuplot as if in gnuplot command promt
c('plot sin(x)')

s(data, filename=’tmp.dat’)

save arrays into file easily read by Gnuplot
s([X,Y,Z])  # creates tmp.dat
c('plot "tmp.dat" u 1:2')

plot(data, filename=’tmp.dat’)

Plot some data. Saves data into filename (default = ‘tmp.dat’) and then sends plot instructions to Gnuplot
plot([x,y])

figure(number=None, term=’x11’)

Create a new or update a figure
figure(1)

p(filename=’tmp.ps’, width=14, height=9, fontsize=12, term=’x11’)

Create postscript file (overwrites existing)
p('myfile.ps')

pdf(filename=’tmp.pdf’, width=14, height=9, fontsize=12, term=’x11’)

Create a pdf file (overwrites existing)
pdf('myfile.pdf')  # creates 'myfile.pdf'

Setup terminal

Default terminal is ‘x11’ unless defined otherwise:
import PyGnuplot as gp
gp.default_term = 'wxt'  # set wxt as default terminal (i.e. on Windows)

Examples:

  • 1 Example code
import PyGnuplot as gp
import numpy as np
X = np.arange(10)
Y = np.sin(X/(2*np.pi))
Z = Y**2.0
gp.s([X,Y,Z])
gp.c('plot "tmp.dat" u 1:2 w lp)
gp.c('replot "tmp.dat" u 1:3' w lp)
gp.p('myfigure.ps')
  • 2 Example file
