termplotlib is a Python library for all your terminal plotting needs. It aims to work
like [matplotlib](https://matplotlib.org/).

### Line plots

For line plots, termplotlib relies on [gnuplot](http://www.gnuplot.info/).
With that installed, the code

```python
import termplotlib as tpl
import numpy as np

x = np.linspace(0, 2 * np.pi, 10)
y = np.sin(x)

fig = tpl.figure()
fig.plot(x, y, label="data", width=50, height=15)
fig.show()
```

produces

```
1 +---------------------------------------+
0.8 | ** ** |
0.6 | * ** data ******* |
0.4 | ** |
0.2 |* ** |
0 | ** |
| * |
-0.2 | ** ** |
-0.4 | ** * |
-0.6 | ** |
-0.8 | **** ** |
-1 +---------------------------------------+
0 1 2 3 4 5 6 7
```

### Horizontal histograms

```python
import termplotlib as tpl
import numpy as np

rng = np.random.default_rng(123)
sample = rng.standard_normal(size=1000)
counts, bin_edges = np.histogram(sample)

fig = tpl.figure()
fig.hist(counts, bin_edges, orientation="horizontal", force_ascii=False)
fig.show()
```

produces

![hist1](https://nschloe.github.io/termplotlib/hist1.png)

Horizontal bar charts are covered as well. This

```python
import termplotlib as tpl

fig = tpl.figure()
fig.barh([3, 10, 5, 2], ["Cats", "Dogs", "Cows", "Geese"], force_ascii=True)
fig.show()
```

produces

```
Cats [ 3] ************
Dogs [10] ****************************************
Cows [ 5] ********************
Geese [ 2] ********
```

### Vertical histograms

```python
import termplotlib as tpl
import numpy as np

rng = np.random.default_rng(123)
sample = rng.standard_normal(size=1000)
counts, bin_edges = np.histogram(sample, bins=40)
fig = tpl.figure()
fig.hist(counts, bin_edges, grid=[15, 25], force_ascii=False)
fig.show()
```

produces

![hist2](https://nschloe.github.io/termplotlib/hist2.png)

### Tables

Support for tables has moved over to
[termtables](https://github.com/nschloe/termtables).

### Installation

termplotlib is [available from the Python Package
Index](https://pypi.org/project/termplotlib/), so simply do

```
pip install termplotlib
```

to install.

### Testing

To run the termplotlib unit tests, check out this repository and type

```
pytest
```
