Heatmap Chart Node

The Heatmap Chart Node visualizes data in a matrix format where individual values are represented by color intensity, making it ideal for identifying patterns, correlations, and trends.

Overview​

This node requires the user to select two category columns (X and Y axes) and a value column. Each cell in the heatmap represents the intersection of the categories, with its color intensity corresponding to the value.

Key Features​

  • Pattern recognition: Easily identify trends and correlations.
  • Customizable color scales: Adjust color gradients for better visualization.
  • Interactive exploration: Integrates with dashboards for dynamic analysis.
  • Supports large datasets: Efficiently handles high-dimensional data.

Required Data​

  • xColumn: The category column for the X axis.
  • yColumn: The category column for the Y axis.
  • valueColumn: The column representing the values.
  • log, polar, movingAvg, to100: Additional display options.

How it works​

  1. Add the Heatmap Chart Node to your workflow.
  2. Connect your dataset.
  3. Select the X and Y category columns and the value column.
  4. Configure display options as needed.
  5. The node renders a heatmap chart.

Use Cases​

  • Website analytics: Visualize user activity by time and page.
  • Correlation analysis: Identify relationships between variables.
  • Resource allocation: Track usage across departments and time periods.
  • Survey analysis: Analyze responses across multiple dimensions.

Benefits​

  • Efficient visualization of complex data.
  • Customizable color scales for enhanced clarity.
  • Interactive exploration for deeper insights.
