[[_TOC_]]

Graph polisher is a library that helps you clean your plotly figures. 
This library was inspired by the book "Storytelling with Data by Cole
Nussbaumer Knaflic (https://www.kobo.com/us/en/ebook/storytelling-with-data).

## Usage

To start our graph polishing, we will create a basic bar graph:

```python
import pandas as pd
import plotly.express as px

report_data = [
    {'name': 'Time Sheets', 'exported': 394},
    {'name': 'Schedules', 'exported': 171},
    {'name': 'overtime', 'exported': 457},
    {'name': 'Time-off', 'exported': 93},
    {'name': 'Shift Requests', 'exported': 30},
]
df = pd.DataFrame(report_data)

fig = px.bar(df, title='Exported Reports', x='name', y='exported')

fig.show()
```

### Cleaning the Graph

Next, we will remove all the unnecessary information from the graph. By removing
unnecessary things from the graph, we will then be able to focus on important
information that will help us drive the user to where we want them to focus on. 

To remove all that default unnecessary information with graph-polisher
do the following:

#### Remove grid lines and background

Grid lines usually compete with the information being shown. If you really think
that you should include them, make them thin and grey so it doesn't call
attention.

```python
import graph_polisher

graph_polisher.remove_grids(figure=fig)
graph_polisher.remove_background(figure=fig) 

fig.show()
```

#### Send to background

The dark colors (black text, bold text) of the graph also calls for attention.
We can easily make them less attention grabbing by sending them to
the background. Sending them to the background will set the text color to a more neutral
color like grey. 

```python
graph_polisher.send_to_background(fig)

fig.show()
```

![Send to backgroung](resources/images/send-to-background.png)

Notice the difference between the default bar graph and our new version. 

| Default Bar Plot                              | No Distractions Bar Plot                                         |
|-----------------------------------------------|:-----------------------------------------------------------------|
| ![Raw Bar Plot](resources/images/raw-bar.png) |  ![Send to backgroung](resources/images/send-to-background.png)  |

Now you have a graph that you can easily add intentional attention grabbing
information so that your user is guided through the information you are trying
to present.

## Deploying pip library

Build the pip library package to deploy to pip:

```shell script
python3 setup.py sdist bdist_wheel
```

Publish to pip. You can follow steps [here](https://docs.gitlab.com/ee/user/packages/pypi_repository/) 

Note that you will need to install twine and register your pypi. Usually in the file
`~/.pypirc`

```shell script
python3 -m twine upload --repository pypi dist/*
```

## Installation

```shell script
pip install graph-polisher
```

## Testing

To test this project run:

```shell script
pytest
```

## Notebook Example (with unnotebook)

Prerequisite: https://www.docker.com/

You can use this to see how the library modifies the plots. We are using 
[unnotebook](http://www.unnotebook.com/) to plot the examples. 

1. Build and push `notebook` image:

```bash
docker build . -t graph-polisher
```

2. Run notebook

```shell script
docker-compose up notebook
```

or 

```bash
docker run --rm -it \
    -v /Users/rigo/Documents/Projects/notebooks/stock-predictions:/notebooks \
    -p 8899:8899 unclutterer
```

3. Open http://localhost:8899/ and open the notebook you want to run.
