I tried using parallel coordinates to visualize outliers. Is it fundamentally correct?

Parallel coordinates visualizing outliers


1 Answer 1


Scatter plot and box plots are the most preferred for visualizing outliers.

Parallel plots can also be utilized for detecting outliers. For large datasets it can be bit confusing, highlighting outliers comes in handy then.
