For a publication I was working on, I plotted functions in PDF format. However, the journal ask me to handle them in EPS format.
“What’s the point?” you might ask. Well, since I installed Lucid Lynx (a clean installation), the files of those graphic were gone… Fool of me, you will say, but really, I never thought that this days journals DO NOT accept PDF files!!!!
Who cares! to the point.
First I tried with the convert command
for i in *.pdf; do convert $i $(echo $i| sed -e s/pdf/eps/g); done
It did the job, but the quality of the plots was compromised.
Then, I move to Sage(math), and re-discover the function ‘graphics_array’, and try this,
p1 = plot(Vn(x, 1, 3), (x,-5,5), color='black', thickness=2)
p1 += plot(Vp(x, 1, 3), (x,-5,5), color='black', thickness=2, linestyle='-.', \
axes_labels=[r'$\xi^\prime', r'$V_{qm}(\xi^\prime)$'], fontsize=17)
p2 = plot(Vn(x, 3, 3), (x,-5,5), color='black', thickness=2)
p2 += plot(Vp(x, 3, 3), (x,-5,5), color='black', thickness=2, linestyle='-.', \
axes_labels=[r'$\xi^\prime$',r''], fontsize=17)
p3 = plot(Vn(x, 5, 3), (x,-5,5), color='black', thickness=2)
p3 += plot(Vp(x, 5, 3), (x,-5,5), color='black', thickness=2, linestyle='-.', \
axes_labels=[r'$\xi^\prime$',r''], fontsize=17)
… a little explanation?! p1, p2 and p3 are the graphics I’d like put into an array, each of them contain 2 plots (both black because otherwise they’ll make me pay an incredible amount of money… crazy people!), and them try the graphics_array,
ga = graphics_array([p1, p2, p3]) ga.show(frame=True, axes=False, figsize=[12,8])
and obtain something like this,
First try with graphics_array
Yeah babe!!!… What???!!! It’s not all right! What happened with the axis labels, the font size, and so on?
Second try: let’s see if the plots are working one by one
p1
This is the right p1
p2
The right p2
p3
The right p3
The are alright! So, What happened? Let me run again the graphics_array commands
ga = graphics_array([p1, p2, p3]) ga.show(frame=True, axes=False, figsize=[12,8])
What did I get?…
The final result was as I wanted to be! 🙂
MORAL: Make Sage(math) show you the plot, one by one, before make them into an array!
Yeah… I almost forgot it!
My goal was to save it as an EPS file, so after getting the looked graph, the command is
ga.save(frame=True, axes=False, figsize=[12,8], \ filename='/path/to/directory/name-of-plot.eps')
Cya all!
