Some plots
##########
Plot 1 does not use context:
.. plot::
plt.plot(range(10))
a = 10
Plot 2 doesn't use context either; has length 6:
.. plot::
plt.plot(range(6))
Plot 3 has length 4, and uses doctest syntax:
.. plot::
:format: doctest
This is a doctest...
>>> plt.plot(range(4))
... isn't it?
Plot 4 shows that a new block with context does not see the variable defined
in the no-context block:
.. plot::
:context:
assert 'a' not in globals()
Plot 5 defines ``a`` in a context block:
.. plot::
:context:
plt.plot(range(6))
a = 10
Plot 6 shows that a block with context sees the new variable. It also uses
``:nofigs:``:
.. plot::
:context:
:nofigs:
assert a == 10
b = 4
Plot 7 uses a variable previously defined in previous ``nofigs`` context. It
also closes any previous figures to create a fresh figure:
.. plot::
:context: close-figs
assert b == 4
plt.plot(range(b))
Plot 8 shows that a non-context block still doesn't have ``a``:
.. plot::
:nofigs:
assert 'a' not in globals()
Plot 9 has a context block, and does have ``a``:
.. plot::
:context:
:nofigs:
assert a == 10
Plot 10 resets context, and ``a`` has gone again:
.. plot::
:context: reset
:nofigs:
assert 'a' not in globals()
c = 10
Plot 11 continues the context, we have the new value, but not the old:
.. plot::
:context:
assert c == 10
assert 'a' not in globals()
plt.plot(range(c))
Plot 12 opens a new figure. By default the directive will plot both the first
and the second figure:
.. plot::
:context:
plt.figure()
plt.plot(range(6))
Plot 13 shows ``close-figs`` in action. ``close-figs`` closes all figures
previous to this plot directive, so we get always plot the figure we create in
the directive:
.. plot::
:context: close-figs
plt.figure()
plt.plot(range(4))
Plot 14 uses ``include-source``:
.. plot::
:include-source:
# Only a comment
Plot 15 uses an external file with the plot commands and a caption (the
encoding is ignored and just verifies the deprecation is not broken):
.. plot:: range4.py
:encoding: utf-8
This is the caption for plot 15.
Plot 16 uses a specific function in a file with plot commands:
.. plot:: range6.py range6
Plot 17 gets a caption specified by the :caption: option:
.. plot::
:caption: Plot 17 uses the caption option.
plt.figure()
plt.plot(range(6))
Plot 18 uses an external file with the plot commands and a caption
using the :caption: option:
.. plot:: range4.py
:caption: This is the caption for plot 18.
Plot 19 uses shows that the "plot-directive" class is still appended, even if
we request other custom classes:
.. plot:: range4.py
:class: my-class my-other-class
Should also have a caption.
Plot 20 shows that the default template correctly prints the multi-image
scenario:
.. plot::
:caption: This caption applies to both plots.
plt.figure()
plt.plot(range(6))
plt.figure()
plt.plot(range(4))
Plot 21 is generated via an include directive:
.. include:: included_plot_21.rst
