32 * Outline |
|
33 - Saving plots. |
|
34 - Plotting in different formats. |
|
35 - Locating the file in the file system. |
|
36 |
|
37 * Creating a basic plot |
|
38 Plot a sine wave from -3pi to 3pi. |
|
39 #+begin_src python |
|
40 In []: x = linspace(-3*pi,3*pi,100) |
|
41 |
|
42 In []: plot(x, sin(x)) |
|
43 #+end_src |
|
44 * savefig() |
|
45 ** savefig() - to save plots |
|
46 : syntax: savefig(fname) |
|
47 ** example |
|
48 *** savefig('/home/fossee/sine.png') |
|
49 - file sine.png saved to the folder /home/fossee |
|
50 - .png - file type |
|
51 |
|
52 * More on savefig() |
|
53 ** Recall |
|
54 - .png - file type |
|
55 ** File types supported |
|
56 *** .pdf - PDF(Portable Document Format) |
|
57 *** .ps - PS(Post Script) |
|
58 *** .eps - Encapsulated Post Script |
|
59 ~to be used with~ LaTeX ~documents~ |
|
60 *** .svg - Scalable Vector Graphics |
|
61 ~vector graphics~ |
|
62 *** .png - Portable Network Graphics |
|
63 ~supports transparency~ |
|
64 * Exercise 1 |
|
65 Save the sine plot in the format EPS which can be embedded in LaTeX documents. |
|
66 * Solution 1 |
|
67 #+begin_src python |
|
68 savefig('/home/fossee/sine.eps') |
|
69 #+end_src |
|
70 * Exercise 2 |
|
71 Save the sine plot in PDF, PS and SVG formats. |
|
72 |
|
73 * Summary |
|
74 You should now be able to |
|
75 - Use ~savefig()~ function |
|
76 - Save plots in different formats |
|
77 - PDF |
|
78 - PS |
|
79 - PNG |
|
80 - SVG |
|
81 - EPS |
|
82 - Locating the files in file system. |
