A Histogram is a diagrammatic representation of a group of data over user-specified ranges. Basically, the histogram contains several bins. Bins are non-overlapping intervals in which the data is spread. The histogram function uses an algorithm that returns bins and bins width are equal. And these bins spread according to the data given in vector. The interesting thing is that the height of each bin represents the number of points in that bin.

Use dot notation to refer to a particular object and property:. Number of bins, specified as a positive integer. If you do not specify NumBins , then histogram automatically calculates how many bins to use based on the input data. Width of bins, specified as a positive scalar. If you specify BinWidth , then Histogram can use a maximum of 65, bins or 2 If the specified bin width requires more bins, then histogram uses a larger bin width corresponding to the maximum number of bins. For datetime and duration data, BinWidth can be a scalar duration or calendar duration. Example: histogram X,'BinWidth',5 uses bins with a width of 5. Edges of bins, specified as a numeric vector. The first element specifies the leading edge of the first bin. The last element specifies the trailing edge of the last bin. The trailing edge is only included for the last bin.

This is particularly useful for quickly modifying the properties of the bins or changing the display. The histogram function uses an automatic binning algorithm that returns bins with a uniform width, chosen to cover the range of elements in X and reveal the underlying shape of the distribution.

Description A histogram shows the distribution of data values. If Y is an m -by- p matrix, hist treats the columns of Y as vectors and returns a by- p matrix n. Each column of n contains the results for the corresponding column of Y. For example, if x is a 5-element vector, hist distributes the elements of Y into five bins centered on the x -axis at the elements in x. Note: use histc if it is more natural to specify bin edges instead of centers. You can use bar xout,n to plot the histogram. Remarks All elements in vector Y or in one column of matrix Y are grouped according to their numeric range. Each group is shown as one bin.

The input, binranges , determines the endpoints for each bin. The output, bincounts , contains the number of elements from x in each bin. If x is a vector, then histc returns bincounts as a vector of histogram bin counts. If x is a matrix, then histc operates along each column of x and returns bincounts as a matrix of histogram bin counts for each column. Use this syntax with any of the previous input argument combinations.

Ability to capture mouse clicks, specified as one of these values: 'visible' — Capture mouse clicks only when visible. Children, returned as an empty GraphicsPlaceholder array or a DataTip object array. Alternatively, you can specify some common colors by name. For example, 'FaceAlpha',0.
