paracoord: Plot 2-dimensional arrays in Parallel coordinates

Purpose

This package is an attempt to implement the idea of parallel coordinates from Sébastien Tricaud and Philippe Saadé to general purposes.

Example

from paracoord import get_paracoord_plot


# Create 10x5 random array
values = np.random.random_sample((10, 5))
print(values)

# Plot parallel coordinates of those values
get_paracoord_plot(values)

# Set arbitrary labels for those 10 5-dimensional vectors
labels = ['aaa', 'bbb', 'aaa', 'ccc', 'bbb', 'aaa', 'aaa', 'bbb', 'aaa', 'ccc']
# Plot them in parallel coordinates with automatically chosen colors
get_paracoord_plot(values, labels=labels)
# Plot them with self defined color dict and save the resulting plot
color_dict = {'aaa': 'b', 'bbb': 'r', 'ccc': 'g'}
get_paracoord_plot(values, labels=labels, color_dict=color_dict, save_path='random_example.jpg', set_legend=True)

Options

• values: 2-dimensional numpy array
• labels: optional, array containing labels for each row of values
• color_dict: dict, optional, ignored if labels not provided. {label -> color} dict. If labels is provided but not color_dict, the color of each label will be automatically chosen
• save_path: path to the file where the resulting image will be stored. If not provided, image will not be stored
• set_legend: boolean, optional, ignored if labelsnot provided. If to set a color legend for the labels or not
• box: boolean. If to set a frame (x-axis, y-axis etc.) for the resulting image
• ylims: (ymin, ymax). If not provided, will be set to the result to get_y_min_nax(values)

Installation

pip install paracoord

Enjoy, do whatever you want with it as long as you don't hold me responsible for the consequences :) Suggestions, remarks, critics, pull requests appreciated
