Parallel Coordinates Plot with MATLAB

This MATLAB tool makes parallel coordinates plots with paper quality. Parallel coordinates plots allows the visualization of high-dimensional data.

The following features are implemented:

• Filtering and sorting of the variables
• Scaling of the range of the variables
• Find the color of the lines composing the plot
• Extract and highlight special lines
• Plot the ranges of the different variables

The tool is able to handle large amount of data:

• For large datasets, a single vector plot is generated
• For large datasets, a vector plot is generated with the axis and a raster plot with the data

Example

In the example, the design space diversity of a medium-frequency transformer is considered:

• run_parse.m - Extract and parse the dataset
• run_plot.m - Make the parallel coordinate plot

Compatibility

The tool is tested with the following MATLAB setup:

• Tested with MATLAB R2018b or 2019a
• No toolboxes are required.
• Compatibility with GNU Octave not tested but probably easy to achieve.
