# gnuplotpy
Basic Python interface to Gnuplot.
Documentation can be found [here](http://gnuplotpy.readthedocs.io/).
Works under Python 2 and Python 3.
## Installation
* pip: `pip3 install gnuplotpy` # or `pip2`
* Arch Linux: `yaourt -S python-gnuplotpy`
### Dependencies
If installing using the [Arch Linux AUR package](https://aur.archlinux.org/packages/python-gnuplotpy/), dependencies will be automatically downloaded and installed, if not, one should ensure the following dependencies are installed:
#### Python
* [setuptools](https://pypi.python.org/pypi/setuptools).
#### Other
* [Gnuplot](http://www.gnuplot.info/).
## Examples
### Passing Python variables to a Gnuplot script:
#### Gnuplot script:
```gnuplot
set datafile separator ','
set term pngcairo size 20cm,20cm
set out filename
unset key
set grid
set border lw 1.5
set title the_title
set xrange [x_max-1.1*x_max:x_max*1.1]
set yrange [-1.1*amp:1.1*amp]
plot data u 1:2 w lp pt 7 ps 0.5 lw 2
set out
```
#### Python script:
```python
import numpy as np
import gnuplotpy as gp
amplitude = 3.
x = np.linspace(0., 2*3.14, 100)
y = amplitude*np.sin(x)
args = {
'the_title': 'Example 1',
'amp': amplitude,
'x_max': x[-1],
'filename': 'example1.png'
}
data = [x, y]
gp.gnuplot('test.gpi', args, data)
```
### Plotting simple 2D and 3D plots:
#### Python script
```python
import numpy as np
import gnuplotpy as gp
x = np.linspace(-5, 5, 100)
y = x**2
gp.gnuplot_2d(x, y, 'example2a.png', 'Example 2a', 'x', 'x^2')
z = np.linspace(0., 2.*np.pi, 10000)
z = z.reshape(100, 100)
z = np.round(np.sin(z), 1)
gp.gnuplot_3d_matrix(z, 'example2b.png', 'Example 2b', 'x', 'y')
```
