Heatmaps use the minor Tick spacing for the size of the tiles..
Zooming can change the Tick settings and thereby affect the Heatmap.
This can be prevented by pressing Shift when changing the axis range.

My wish:
An option for GraphBuilder/Heatmap to forces JMP to fix the tick spacing and thereby the tile aggregation area (esp: 1x1)?
Such that accidental changes of the settings can be prevented.

Holger
