[QGIS-Developer] missing matplotlib.pyplot python module

[Idan Miara]

Hi,

I try to import matplotlib.pyplot from python shell in QGIS (2.18 or 2.99).
It imports OK if I run it from QGIS internal python shell but it fails if I
run it from python outside QGIS (running python via OSGeo4W.bat).

it might have something to do with Tkinter.

code examples:
1.
import matplotlib
dir(matplotlib)

-> yields a shorter list (laking pyplot among others) if run from outside
QGIS.

2.
import matplotlib.pyplot as plt

-> Success from QGIS, but gives the following error if run from outside.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File
"c:\PROGRA~1\QGIS2~1.18\apps\Python27\lib\site-packages\matplotlib\pyplot.py",

    mod = mod._resolve()

    return _import_module(self.mod)
  File "c:\PROGRA~1\QGIS2~1.18\apps\Python27\lib\site-packages\six.py",
line 82, in _import_module
    __import__(name)
ImportError: No module named Tkinter

Thanks,
Idan
