## Tables

### Usage

Requires Python 3.6 or greater and the [wcwidth library](https://pypi.org/project/wcwidth/), which users can install with:
```bash
pip3 install wcwidth
# or
python3 -m pip install wcwidth
```
See the [tables.py](tables.py) file for full usage information.

Complete versions of all of the examples below and more can be found in the [test.py](test.py) file.

Run with: `python3 test.py`.

#### Output str array as table

```py
import tables

# Set array

tables.array(array, headerrow=True, headercolumn=True)
```

Table cells can contain [Unicode characters](https://en.wikipedia.org/wiki/List_of_Unicode_characters), but not newlines and tabs.

#### Output array as table with separate header row and column

```py
import tables

headerrow = ["Header row/column 1", "Header row 2", "Header row 3", "Header row 4", "Header row 5"]
headercolumn = ["Header column 2", "Header column 3", "Header column 4", "Header column 5"]

# Set array

tables.array(array, headerrow, headercolumn, headerrow=True, headercolumn=True)
```

Output same as example above.

#### Output array as table

```py
import tables

# Set array, can be any sequence data type

tables.array(array)
```

#### Output sorted array as table

```py
import tables

# Set array

sortdimension = 0  # Column to sort by

array = sorted(array, key=lambda x: x[sortdimension])

tables.array(array)
```

## Graphs/Plots

### Usage

Requires Python 3.6 or greater and the [wcwidth library](https://pypi.org/project/wcwidth/), which users can install with:
```bash
pip3 install wcwidth
# or
python3 -m pip install wcwidth
```
See the [graphs.py](graphs.py) file for full usage information.

Complete versions of all of the examples below and more can be found in the [test.py](test.py) file.

Run with: `python3 test.py`.

If `height` is `0`, it will be set to the current height of the terminal (number of rows times four). If `width` is `0`, it will be set to the current width of the terminal (number of columns times two).

#### Output single array as plot

```py
import graphs

height = 160
width = 160

xmin = -20
xmax = 20
ymin = -20
ymax = 20

# Set array, can be any sequence data type, but must have exactly two columns

graphs.array(height, width, xmin, xmax, ymin, ymax, array)
```

If `xmin` and `xmax` are both `0`, they will be set to the respective minimum and maximum values of x in the array. If `ymin` and `ymax` are both `0`, they will be set to the respective minimum and maximum values of y in the array.

![](../images/array%20to%20plot.png)

Use `graphs.arrays()` to plot multiple arrays, which can be of different sizes.

#### Output single function as graph

```py
import graphs

def afunction(x):
	return x + 1

height = 160
width = 160

xmin = -20
xmax = 20
ymin = -20
ymax = 20

graphs.function(height, width, xmin, xmax, ymin, ymax, afunction)
```

![](../images/function%20to%20graph.png)

#### Output lambda function as graph

```py
import graphs

height = 160
width = 160

xmin = -20
xmax = 20
ymin = -20
ymax = 20

afunction = lambda x: x + 1

graphs.function(height, width, xmin, xmax, ymin, ymax, afunction)
```

Output same as example above.

#### Output multiple functions as graph

```py
import graphs

def function1(x):
	return 2 * x

def function2(x):
	return x ** 2

height = 160
width = 160

xmin = -20
xmax = 20
ymin = -20
ymax = 20

# Function parameter and return value can be any data type, as long as they are the same
functions = [function1, function2]

graphs.functions(height, width, xmin, xmax, ymin, ymax, functions)
```
