# Termgraph

A command-line tool and Python library that draws basic graphs in the terminal.

Graph types supported:
- Bar Graphs
- Color charts
- Multi-variable
- Stacked charts
- Histograms
- Horizontal or Vertical
- Calendar heatmaps
- Emoji!

## Quick Start

### Command Line Usage

```
$ 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
```

### Python Module Usage

```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()
```

Output:
```
# Quarterly Sales

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

## More Examples

### Custom Tick Marks

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

```

### Color Charts

Note: Color charts use ANSI escape codes, so may not be able to copy/paste from terminal into other uses.

```bash
$ termgraph data/ex4.dat --color {cyan/yellow} --space-between
```

---

```
termgraph data/ex7.dat --color {green,magenta} --stacked
```

![Stacked Bar Chart](/docs/assets/barchart-stacked.svg)

### Calendar Heatmap

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

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

## 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

#### Command Line Arguments

```
usage: termgraph [-h] [options] [filename]

draw basic graphs on terminal

### Python API

All chart types are available as classes:

```python
from termgraph import (
    Data, Args,
    BarChart, StackedChart, VerticalChart, HistogramChart
)

# Basic setup
data = Data([[10], [20]], ["A", "B"])
args = Args(title="My Chart")

# Choose your chart type
chart = BarChart(data, args)        # Horizontal bars
# chart = StackedChart(data, args)  # Stacked bars
# chart = VerticalChart(data, args) # Vertical bars
# chart = HistogramChart(data, args) # Histogram

chart.draw()
```

Quick Args options:
- `title`: Chart title
- `width`: Width in characters (default: 50)
- `format`: Number format string (default: "{:<5.2f}")
- `suffix`: Add suffix to all values
- `no_labels`: Don't show labels
- `no_values`: Don't show values
- `colors`: List of color names

## 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.
