6. Click a Histogram Scaling option:
H
Linear displays histogram data linearly. Bin counts
smaller than the maximum counts are scaled
linearly by dividing the bin count by the maximum
bin count.
Horizontal histograms have a maximum of 500 bins
while vertical histograms have a maximum of 200
bins.
H
Log displays histogram data logarithmically. Bin
counts smaller than the maximum counts are
scaled logarithmically. Logarithmic scaling provides
better visual details for bins with low counts.
