morebins

Increase number of histogram bins

Syntax

N = morebins(h)

N = morebins(h,direction)

Description

N = morebins(h) increases the number of bins in histogram h by 10% (rounded up to the nearest integer) and returns the new number of bins.

For bivariate histograms, this increases the bin count in both the x and y directions.

N = morebins(h,direction), where h must be a histogram2 object, only increases the number of bins in the dimension specified by direction. The direction option can be 'x', 'y', or 'both'. The default value is 'both'.

Examples

Increase Number of Histogram Bins

Plot a histogram of 1,000 random numbers and return a handle to the histogram object.

x = randn(1000,1);
h = histogram(x)

h =

Use morebins to increase the number of bins in the histogram.

morebins(h);

Input Arguments

h — Input histogram

histogram object | histogram2 object

Input histogram, specified as a histogram or histogram2 object.

h cannot be a categorical histogram.

direction — Direction to increase number of bins

'both' (default) | 'x' | 'y'

Direction to increase the number of bins, specified as 'x', 'y', or 'both'. Specify 'x' or 'y' to only increase the number of bins in that direction while leaving the number of bins in the other direction constant.

Output Arguments

N — Number of bins

scalar | vector

Number of bins, returned as a scalar or vector. N is the new number of bins for the histogram after increase. For bivariate histogram plots, N is a two-element vector, [nx ny].
