BinCounts

BinCounts[data]

counts the number of elements of data whose values lie in successive integer bins.

BinCounts[data,binspec]

counts the number of elements of data whose values lie in successive bins specified by binspec.

Details

  • BinCounts drops elements whose values do not correspond to real numbers.
  • The following bin-width specifications binspec can be given:
  • dxbins of width dx »
    {xmin,xmax,dx}bins of width dx from xmin to xmax »
    {{b1,b2,…}}the intervals [b1,b2), [b2,b3), … »
    xbins,ybins,…bin specifications for multivariate data understood as {{x1,y1,…},{x2,y2, …},…} »
  • BinCounts[data,dx] takes the bin boundaries to be integer multiples of dx, with the first bin starting at Ceiling[Min[data]-dx,dx] and the last bin ending at Floor[Max[data]+dx,dx].
  • BinCounts[data] is equivalent to BinCounts[data,1].
  • In BinCounts[data,{xmin,xmax,dx}], elements are counted in bin i when their values satisfy .
  • BinCounts[data,{xmin,xmax}] is equivalent to BinCounts[data,{xmin,xmax,1}].
  • In BinCounts[data,{{b1,b2,…}}], elements are counted in bin i when their values satisfy .
  • In the form BinCounts[data,{{b1,b2,…}}], the bi at each end can be -Infinity and +Infinity.
  • If the bi do not form an increasing sequence, they are automatically sorted by BinCounts.
  • If data consists of length-n sublists, then n bin specifications must be given, and BinCounts[data,…] yields an array of depth n.
  • The data can have the following forms and interpretations:
  • {x1,x2,…}list of real numbers or quantities »
    {{x1,y1,…},{x2,y2,…},…}list of vectors of the same dimension »
    SparseArrayan array equivalent to Normal[data] »
    QuantityArrayarray of column-compatible quantities »
    TimeSeries, TemporalData,…vector or array of values (the time stamps ignored) »

Basic Examples  (3)

Count the number of elements in bins of a specified width:

Count the number of elements in bins of width 1 from 0 to 10:

Count the number of elements in a sequence of ranges:

Scope  (11)

Basic Uses  (8)

Count squares mod 3 and 5 in two-dimensional unit bins:

Count random pairs in bins of width 0.25 in both dimensions:

Count multidimensional data in ranges:

Count data in any dimension:

Count binned data, ignoring values that are not real:

Count binned data of any precision:

SparseArray data can be used just like dense arrays:

Count the values of data in a time series:

The time stamps are ignored:

Data with Quantities  (3)

Bin quantity data:

Automatic bins:

Specify bin width:

Bins of fixed width, minimum and maximum:

Specify bin intervals:

Bin mixed type data:

The units are compatible for each dimension:

Specify bin width for each dimension:

QuantityArray can be used just like arrays:

Automatic bins:

Specify bin width in compatible units:

Applications  (1)

Visualize the density of two-dimensional data in bins:

Properties & Relations  (1)

The results from BinCounts are equivalent to the lengths of BinLists:

For list of vectors:

Possible Issues  (4)

Binning intervals are closed on the left:

For data involving quantities, the bin specification must be given in compatible units:

Matrix data must have unit-compatible columns:

The bins obtained using the specification {min,max,dx} may not include all data points:

Specify the min and max so all data points are included in the bin covering:

Alternatively, use the width-only bin specification dx:
