Data Visualization - Parallel Coordinates chart


Parallel Coordinates charts are powerful visualization tools that enable users to explore relationships between multiple variables simultaneously. OtasML, a visual machine learning tool, offers a Parallel Coordinates Chart feature within its data preparation model. This feature allows users to create customizable parallel coordinates plots, providing insights into patterns and trends across various dimensions of their data. This article explains how to configure the Parallel Coordinates Chart feature to enhance your data visualization.


The Parallel Coordinates Chart tool in OtasML provides various options for customizing and visualizing data points, allowing users to tailor the appearance and dimensions of their charts. Below are the key configurations and options available:


  • Default Value: None
  • Description: This option allows users to select specific columns for visualizing their data. By specifying the subset of columns, users can focus on the variables of interest, ensuring that the parallel coordinates chart provides meaningful insights.


  • Default Value: None
  • Description: Provide a specific height value for the chart. Only integer values are allowed. Setting a height helps maintain the aspect ratio of the chart, ensuring that the visualization is clear and well-proportioned.


  • Default Value: None
  • Description: This option allows users to specify the color of different elements in the chart. By customizing the colors, users can enhance the visual appearance of the chart, making it easier to distinguish between different data points and dimensions.

Interactive Button: Preview

To enhance user experience and provide greater control over the parallel coordinates chart visualization, the tool includes a Preview button:

  • Preview: This button allows users to see the effects of their configuration in real-time without permanently applying the changes. By clicking Preview, users can visually assess how the parallel coordinates chart will appear based on the current configurations, ensuring that the visualization is appropriate before committing to any changes.


The Parallel Coordinates Chart tool in OtasML provides a flexible solution for visualizing relationships between multiple variables in a dataset. By allowing users to select specific columns, set the chart height, and customize colors, the tool offers greater flexibility and control over the data visualization process. The inclusion of an interactive Preview button further enhances the user experience, ensuring confidence in the parallel coordinates chart configuration. OtasML continues to empower users with intuitive and effective tools, making data visualization a seamless and integral part of the machine learning workflow.
