Histogram Chart Node

The Histogram Chart Node visualizes the distribution of a numeric variable by dividing the data into bins and displaying the frequency of each bin.

Overview​

Users must select a category column and specify the number of bins. Optionally, a sub-category column can be used for grouped histograms.

Key Features​

  • Distribution analysis: Shows how data is distributed across intervals.
  • Customizable bins: Set the number of bins for granularity.
  • Grouped histograms: Compare distributions across categories.

Required Data​

  • categoryColumn: The numeric column to bin.
  • bins: Number of bins.
  • subCategoryColumn (optional): For grouped histograms.

How it works​

  1. Add the Histogram Chart Node to your workflow.
  2. Connect your dataset.
  3. Select the category column and number of bins.
  4. Optionally, select a sub-category column.
  5. The node renders a histogram.

Use Cases​

  • Distribution analysis: Understand how values are spread.
  • Outlier detection: Spot unusual values.
  • Comparing groups: Analyze distributions across categories.

Benefits​

  • Clear visualization of data distributions.
  • Flexible binning for detailed analysis.
  • Supports large datasets efficiently.
