Description

Parallel plot or parallel coordinates plot allows to compare the feature of several individual observations ( series ) on a set of numeric variables. Each vertical bar represents a variable and often has its own scale. (The units can even be different)

Purpose :

The purpose of a parallel coordinates line chart is to visually represent and analyze multivariate data in a two-dimensional space. Some key purposes include:

  1. Identifying Patterns: It allows for the identification of patterns, trends, and relationships across multiple variables simultaneously, enabling analysts to uncover complex insights within the data.
  2. Correlation Analysis: By observing the behavior of lines as they intersect and converge, analysts can assess correlations between different variables, helping to understand how they interact with each other.
  3. Outlier Detection: Parallel coordinates charts facilitate the detection of outliers or anomalous data points by visually inspecting deviations from the general trend of the data.
  4. Data Exploration: It provides a comprehensive overview of the dataset, allowing users to explore the distribution and spread of values across multiple dimensions and identify interesting subsets for further analysis.
  5. Dimensionality Reduction: Parallel coordinates charts can aid in reducing the dimensionality of complex datasets while preserving important information, making it easier to interpret and analyze large amounts of data.
  6. Comparative Analysis: Users can compare the relationships between variables for different subsets or categories within the data, enabling comparative analysis across various groups or time periods.

Overall, the purpose of a parallel coordinates line chart is to facilitate visual exploration, analysis, and interpretation of multivariate data, helping users gain valuable insights and make informed decisions based on their findings.

 

Uses :

Parallel coordinates have several uses across various fields:

  1. Exploratory Data Analysis: Parallel coordinates enable analysts to explore complex multivariate datasets by visually examining relationships, trends, and patterns across multiple variables simultaneously.
  2. Pattern Recognition: They facilitate the identification of patterns and structures within datasets, aiding in understanding the underlying relationships between variables and uncovering insights that may not be apparent in traditional plots.
  3. Correlation Analysis: Parallel coordinates are effective for assessing correlations between variables by observing how lines intersect and converge across different axes, helping to identify relationships and dependencies between variables.
  4. Outlier Detection: Anomalies or outliers in the data can be identified visually as data points that deviate significantly from the overall trend of the lines, aiding in outlier detection and data quality assessment.
  5. Classification and Clustering: Parallel coordinates can be used as a preprocessing step for classification and clustering tasks, helping to visualize and understand the distribution of data points across different classes or clusters.
  6. Dimensionality Reduction: They offer a way to reduce the dimensionality of high-dimensional datasets while preserving essential information, making it easier to visualize and interpret complex data.
  7. Feature Selection: Parallel coordinates can assist in feature selection by visually examining the importance and relevance of different variables in predicting or explaining the target variable.
  8. Interactive Visualization: When used in interactive visualization tools, parallel coordinates allow users to dynamically explore and interact with the data, facilitating more intuitive data exploration and analysis.

Overall, parallel coordinates are a versatile visualization technique that can be applied across various domains, including data analysis, machine learning, exploratory data mining, and scientific visualization.
