The zonal histogram is not generated by the raster band setting and the raster value is listed as the field value of the output.

For example,
the raster band type is singleband pseudocolor,
rast value range = 0 ~ 100
band is classified by 5 (20, 40, 60, 80 ,100)

But oustput is stragne like below

HISTO_10 int8 1 0
HISTO_10.0033 int8 -1 0
HISTO_10.004 int8 -1 0
HISTO_10.0041 int8 -1 0
HISTO_100.0 int8 -1 0

Is it normal output?
I expect this function is same zonal histtogram in Arcgis
