DefinedBytes HeatMapster 1.0.1 (x64)
 

Fast Data Import (Excel & CSV)
Import .xlsx, .xls, and .csv files with a guided workflow. Supports both Matrix format (recommended) and Tabular format (X / Y / Value).
Professional Color Palettes & Range Stops
Choose from sequential and diverging palettes (including colorblind-friendly options like Viridis and Plasma). Control color distribution with presets such as Equal Interval, Quantile, Extremes, Logarithmic, and Three-Class, or create your own custom stops.
Normalization (Global / Per Row / Per Column)
Compare values fairly using normalization modes:
Min-Max, Z-Score, and Percentiles - globally or independently per row/column.
Filtering & Sorting
Filter by value range and by selected X/Y categories. Sort axes by original order, alphabetical, sum, or max (ascending/descending) to reveal structure in your data.
Labels, Tooltips & Readability
Toggle cell labels, set precision, and enable Auto Contrast (black/white text) for readability.
Transpose & Layout Tools
Transpose the matrix (swap X/Y), rotate axis labels, adjust font size, and customize titles (chart, axes, legend).
Export & Print
Export your heatmap to PNG, JPG, SVG, and PDF, or print directly.
