How to go from bare windows machine to plotting graphs in Python (Amazingly complicated but should be very repeatable...)

simple_plot.py

#!/home/smeckley/py/venvs/venv1/bin/python
# All the steps required to get this simple plot:
# 1) Install VM VirtualBox on my windows machine
# 2) Download LinuxMixt (LMDE4) .iso
# 3) Create new VM for Linux Ubuntu and load .iso into the virtual optical drive
# 4) Startup the VM and click on "install" icon on the desktop (follow propmts)
# 5) Once finished with the basic install we need to enable "Guest Additions" to share clipboard/resize screen (all the goodies) VM->Devices->"Install Guest Additions CD Image" and run that
# 6) Install gvim (WTF!!) "sudo apt install vim-gtk3"
# 7) Get Python working with the correct libraries
#    sudo su
#      update-alternatives --install /usr/bin/python python /usr/bin/python3 1; # Sets python3 as the default
#      exit
#    sudo apt install python3-pip
#    sudo apt install python3-venv
#    sudo apt-get install python3-tk
#    mkdir -p ~/py/venvs/
#    pushd ~/py/venvs/
#    python -m venv venv1
#    source ~/py/venvs/venv1/bin/activate
#    python -m pip install numpy scipy matplotlib ipython jupyter pandas sympy nose
#  8) Create this file and go! Easy peasy.....

import matplotlib
import matplotlib.pyplot as plt
import numpy as np

# Data for plotting
t = np.arange(0.0, 2.0, 0.01)
s = 1 + np.sin(2 * np.pi * t)

fig, ax = plt.subplots()
ax.plot(t, s)

ax.set(xlabel='time (s)', ylabel='voltage (mV)',
               title='About as simple as it gets, folks')
ax.grid()

fig.savefig("test.png")
plt.show()
