- Traditional overlay plots: Displaying multiple chromatograms on same axes with different colors. Works well for 2-5 samples allowing detailed comparison. Becomes cluttered with many samples limiting usefulness.
- Heatmap advantages: Handles dozens to hundreds of chromatograms without visual clutter. Pattern recognition easier than comparing individual overlays. Quickly identifies outliers (samples appearing different from group). Ideal for large-scale quality control or stability studies.
- Complementary approaches: Use heatmaps for initial screening identifying interesting samples (outliers, trends). Follow with detailed overlay plots examining specific samples closely. Heatmaps provide big picture, overlays enable detailed analysis. Understanding data visualization methods optimizes analytical workflows.
