Parallel Coordinates plotting
Project description
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 labels
not 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)
Final note
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
