# fewerbins

Decrease number of histogram bins

## Syntax

``N = fewerbins(h)``
``N = fewerbins(h,direction)``

## Description

example

````N = fewerbins(h)` decreases the number of bins in histogram `h` by 10% (rounded down to the nearest integer) and returns the new number of bins.For bivariate histograms, this decreases the bin count in both the x and y directions.```
````N = fewerbins(h,direction)`, where `h` must be a `histogram2` object, only decreases 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

collapse all

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

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

```h = Histogram with properties: Data: [1000x1 double] Values: [1x23 double] NumBins: 23 BinEdges: [1x24 double] BinWidth: 0.3000 BinLimits: [-3.3000 3.6000] Normalization: 'count' FaceColor: 'auto' EdgeColor: [0 0 0] Show all properties ```

Use `fewerbins` to decrease the number of bins in the histogram.

```fewerbins(h); fewerbins(h)```

```ans = 18 ```

## Input Arguments

collapse all

Input histogram, specified as a `histogram` or `histogram2` object.

`h` cannot be a categorical histogram.

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

## Output Arguments

collapse all

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]```.
