# Termgraph

A command-line tool that draws basic graphs in the terminal, written in Python.

Graph types supported:

- Bar Graphs
- Color charts
- Multi-variable
- Stacked charts
- Histograms
- Horizontal or Vertical
- Emoji!


### Examples

```
termgraph data/ex1.dat

# Reading data from data/ex1.dat

2007: ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 183.32
2008: ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 231.23
2009: ▇ 16.43
2010: ▇▇▇▇ 50.21
2011: ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 508.97
2012: ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 212.05
2014: ▏ 1.00
```

An example using emoji as custom tick:

```
termgraph data/ex1.dat --custom-tick "🏃" --width 20 --title "Running Data"

# Running Data

2007: 🏃🏃🏃🏃🏃🏃🏃 183.32
2008: 🏃🏃🏃🏃🏃🏃🏃🏃🏃 231.23
2009:  16.43
2010: 🏃 50.21
2011: 🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃🏃 508.97
2012: 🏃🏃🏃🏃🏃🏃🏃🏃 212.05
2014:  1.00

```


An example using stdin and emoji:

```
echo "Label,3,9,1" | termgraph --custom-tick "😀" --no-label


😀😀😀 3.00
😀😀😀😀😀😀😀😀😀 9.00
😀 1.00

```

Most results can be copied and pasted wherever you like, since they use standard block characters. However the color charts will not show, since they use terminal escape codes for color. A couple images to show color examples:

```
termgraph data/ex4.dat --color {blue,red}
```

```
termgraph data/ex7.dat --color {yellow,magenta} --stacked --title "Stacked Data"
```

Calendar Heatmap, expects first column to be date in yyyy-mm-dd

```
termgraph --calendar --start-dt 2017-07-01 data/cal.dat
```

### Install

Requires Python 3.9+, install from [PyPI project](https://pypi.org/project/termgraph/)

```
python3 -m pip install termgraph
```

Note: Be sure your PATH includes the pypi install directory, for me it is `~/.local/bin/`

### Usage

#### Command Line Interface

* Create data file with two columns either comma or space separated.
  The first column is your labels, the second column is a numeric data

* termgraph [datafile]

* Help: termgraph -h

#### Programmatic API

Termgraph can also be used as a Python library for creating charts programmatically:

```python
from termgraph import Data, Args, BarChart

# Create data
data = Data([[10], [25], [50], [40]], ["Q1", "Q2", "Q3", "Q4"])

# Configure chart options  
args = Args(
    title="Quarterly Sales",
    width=50,
    format="{:.0f}",
    suffix="K"
)

# Create and display chart
chart = BarChart(data, args)
chart.draw()
```

This produces:
```
# Quarterly Sales

Q1: ▇▇▇▇▇▇▇▇▇▇ 10K
Q2: ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 25K  
Q3: ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 50K
Q4: ▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇ 40K
```

```

```


### Background

I wanted a quick way to visualize data stored in a simple text file. I initially created some scripts in R that generated graphs but this was a two step process of creating the graph and then opening the generated graph.

After seeing [command-line sparklines](https://github.com/holman/spark) I figured I could do the same thing using block characters for bar charts.
