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 the specified bin width and may be greater than the specified right histogram limit (to:
field) as shown on the screenshot above. Enter round value in the From:
field if you want the lower limit of the first bin to be round.
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.
This option is used when the histogram is recalculated. Recalculation may be cause by input data change (if Auto Recalculate
checkbox is selected) or invoked manually (Recalculate
menu item in histogram table column context menu).
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.
