Used to determine the heatmap grid level to compute, defaulting to 0.15. It has the same interpretation of distErrPct when searching on RPT, but relative to the shape in 'bbox'. It's a fraction (not a %) of the radius of the shape that grid squares must fit into without exceeding. > 0 and <= 0.5. Mutually exclusive with distErr & gridLevel.- See Also:

-
FACET_HEATMAP_DIST_ERR
static final String FACET_HEATMAP_DIST_ERR
Used to determine the heatmap grid level to compute (optional). It has the same interpretation of maxDistErr or distErr with RPT. It's an absolute distance (in units of what's specified on the field type) that a grid square must maximally fit into (width & height). It can be used to to more explicitly specify the maximum grid square size without knowledge of what particular grid levels translate to. This can in turn be used with knowledge of the size of 'bbox' to get a target minimum number of grid cells. Mutually exclusive with distErrPct & gridLevel.- See Also:
- Constant Field Values

FACET_HEATMAP_MAX_CELLS
static final String FACET_HEATMAP_MAX_CELLS
