Open Table or Figure or Fit Plot with initial data and select Processing → Histogram
menu item to calculate histogram.
You can either set the bin width/count manually or specify auto binning criteria.
MagicPlot align the the lower limit of the first bin exactly at the beginning of specified histogram range (From:
field). The upper limit of the last bin is calculated on the basis of bin width and may be greater than the specified right histogram limit (to:
field) as shown on the screenshot above.
k=…
means setting the number of bins k
h=…
means setting the bin width h
.k=sqrt(n)
h=3.49*s/n^(1/3)
(Scott's formula)k=log2(n)+1
(Sturges' formula)n
— the number of data pointss
— data standard deviationm
— data meanmin
— data minimummax
— data maximum.The preview plot shows the histogram which is evaluated according to selected parameters. It also shows the data point positions on X axis in the bottom of the plot.
