Format multiples of pi as strings on Matplotlib axes.

The `MultiplePi` class creates a [Locator](https://matplotlib.org/api/ticker_api.html?highlight=locator#matplotlib.ticker.MultipleLocator) to place ticks at desired multiples and a [Formatter](https://matplotlib.org/api/ticker_api.html?highlight=locator#matplotlib.ticker.FuncFormatter) to format all tick labels.

The base (π or τ) can be divided by any Natural Number.

Multiples of one-π or one-τ can be placed/formatted too. (2π, 3π, 2τ, 3τ, etc.)

## Installing

```bash
pip install matplot-fmt-pi
```

## Examples

```python
from matplot_fmt_pi.ticker import MultiplePi
```

Simply, the instance can be asssigned a denominator of pi then passed to matplotlib.

![Graph Example](https://raw.githubusercontent.com/k-donn/format-pi/master/examples/pi_graph.png)

The parameters can also be modified to adjust the output to something more sophisticated.

![Tau Graph Example](https://raw.githubusercontent.com/k-donn/format-pi/master/examples/tau_graph.png)

![Y-Axis Example](https://raw.githubusercontent.com/k-donn/format-pi/master/examples/pi_y_axis.png)

## Running Examples

Clone, then from the repo,

```bash
cd examples/
python *.py
```

Put the repo's directory in the python path to import the `matplot_fmt_pi` folder not the installed package.

```bash
PYTHONPATH=/home/user/py-pros/format-pi python examples/pi_graph.py
```

## Todo

-   [ ] Add testing option once installed (Like `numpy.test()`)
-   [ ] Windows `make.bat`?
