Histogram - Create a histogram
Data frequency distribution
Histogram < in.H ninterv=50 | Graph | Tube
[50,...] : Number of intervals (default equals 50)
interval step
minimum data value
maximum data value
[1] or 2(or 3(...))): computes histogram for every trace (or plane(or cube(...)))
dinterv = (max - min)/ninterv
Histogram computes automatically the maximum and minimum values of your dataset, but you can choose to overwrite these values, specifying min and max. Cube may be up to 4-dimensions.
The default value for the parameter dim is the highest dimension of your dataset. The parameters ninterv, dinterv, min, and max accept multiple entries separated with commas.
For example, for the dataset in.H with n1=3, n2=4, n3=2 n4=2:
Histogram < in.H ninterv=10,11,12,10 dinterv=20,30,35,40 dim=2 | Graph movie=y | Tube
will display 4 histograms. Each histogram will have a different number of intervals, and a different number of interval step.
