Setting up virtual environment

In order to better manage packaging in python, this project uses pipenv for version and dependency management.

To install pipenv on your machine, run:

$ pip install --user pipenv

Note: This does a user installation to prevent breaking any system-wide packages. If pipenv isn’t available in your shell after installation, you’ll need to add the user base’s binary directory to your PATH.

On Linux and macOS you can find the user base binary directory by running python -m site --user-base and adding bin to the end. For example, this will typically print ~/.local (with ~ expanded to the absolute path to your home directory) so you’ll need to add ~/.local/bin to your PATH. You can set your PATH permanently by modifying ~/.profile.

On Windows you can find the user base binary directory by running python -m site --user-site and replacing site-packages with Scripts. For example, this could return C:\Users\Username\AppData\Roaming\Python36\site-packages so you would need to set your PATH to include C:\Users\Username\AppData\Roaming\Python36\Scripts. You can set your user PATH permanently in the Control Panel. You may need to log out for the PATH changes to take effect.

After installing pipenv, cd into the source directory and run:

$ pipenv shell

to create the virtual environment.

$ pipenv install

installs all dependencies in the Pipfile.

$ pipenv run python read_power.py

runs read_power script, or you can activate shell and run directly (without pipenv run) there.

Troubleshooting

In order to access the power meters, you must be connected to UCSD-PROTECTED. If you are having trouble with dependencies, (runtime errors with import statements) run pipenv --rm to nuke virtual environment, and re-create it with pipenv shell. You should not be using pip as your package manager when working in this environment. If you want to add a new package during development, use pipenv install <package>. This will ensure it is added as a dependency so that it is reproducible across environments.

Fix x-axis on graphs

X-axis is zero-indexed. Make sure that Xmax is equivalent to the number of observations inputted by the user.

Label axes

Label the x and y-axis of our produced figures

Add more comments to code

Vignesh told us to add more comments to our code, including headers before functions and stuff like that. He said we should have "more comments than code".
