  1. The small preview locates the inspected position; Column and Line identify native coordinates.
  2. Component readouts and the swatch describe the position. Sample size changes the averaging footprint.
  3. The graph follows the selected scanline. Connect changes with picture edges in the stadium preview.

Try it yourself.

  1. Choose a digital chip-chart or sunlit-interior sample.
  2. Select a patch interior and compare sample sizes 1, 3 and 5.
  3. Move across a boundary, watching numeric values and the scanline.

Useful controls.

  • Column and Line select the position.
  • Component choices select plotted quantities.
  • Sample size sets averaging; analysis masks determine included samples.

Use patch interiors for reference comparisons. The full sample neighborhood must be included for an averaged readout.
