Heat Map Example

Context​

A Heatmap is a data visualization technique that represents values as colors in a matrix format. It is useful for identifying patterns, correlations, and variations across multiple data points. Colors indicate intensity or frequency, making heatmaps effective for comparative analysis.

Inputs​

  • Categories on Y-axis (categorical variable)
  • Fields on X-axis (numerical or categorical variable)

Settings​

  • Chart Name (customizable title)
  • Chart Legend (define or modify legend text)

Axis Controls​

  • Rotate Y-axis Labels (toggle label orientation for readability)
  • Y-axis Text Size (adjustable via slider)
  • Y-axis Width (modify axis width for layout optimization)
  • Rotate X-axis Labels (toggle orientation for better fit)
  • X-axis Text Size (adjustable via slider)
  • X-axis Height (modify spacing to accommodate longer labels)
  • Right Y-axis Size (adjust axis size for layout balance)

Data Processing​

  • Cluster Rows (group and order rows based on similarity)
  • Cluster Columns (group and order columns based on similarity)
  • Averaging Method
    • Mean (average value calculation)
    • Median (middle value calculation)

Color Settings​

  • Show Color Legend (enable/disable color legend)
  • Log Color Scale (apply logarithmic scaling for better contrast)
  • Trim to Percentile
    • No Trim
    • 0.001 (removes extreme values beyond this percentile)
    • 0.01
    • 0.05
