Color maps

Select a color map from the toolbar dropdown. The choice is saved and applied to all image and heatmap views. Available palettes: viridis, plasma, inferno, magma, hot, greys, RdBu, turbo.

Cross-section plots

  • Column profile (top-right, rotated) — intensity vs. row at the selected column; row axis is vertical so it aligns with the image
  • Row profile (bottom-left) — intensity vs. column at the selected row

Both plots extend a dashed crosshair line to show where the slice was taken. Click Analyze to open a profile in the analysis panel.

Multi-frame datasets

When a field has shape [nFrames, H, W], a frame slider appears in the toolbar. Drag it to step through frames; each frame is fetched and cached on demand.
