Basic 2D plots, good 3D graphics, and even animation possibilities are available in an easy environment.The most basic and useful command for producing simple 2D plots is By doing 'tic-tocs' I found out that these precise lines were taking up 90% of the execution time. Is there any way to have access to the histogram data without opening a figure, or any other way of optimizing time ? How can I plot 2d data with hist3() in an Axes Learn more about histogram, plotting, app designer MATLAB It creates a 2D histogram with the outputs you want. That is why I gave you a link to it. Note that it is a third-party function, so you will need to download it and put in on your MATLAB path or in the current directory. The download button is in the top right corner, labelled "Download Zip". 2010-01-22 · This short video makes a 2d histogram as an alternative to plotting data points and visually estimating where the most data is.

The histcounts2 function uses an automatic binning algorithm that returns uniform bins chosen to cover the range of values in X and Y and reveal the underlying shape of the distribution. This Matlab code creates a histogram with 3 bars. The first bar has two '1' values, the second bar has three '2' values, and the third bar has one '3' values. y = [1 1 2 2 2 3] hist (y) The horizontal axis has the different values in the vector to be plotted. Specify a third output for histcounts to return a vector representing the bin indices of the data. X = randi ( [-5,5],100,1); [N,edges,bin] = histcounts (X, 'BinMethod', 'integers' ); Find the bin count for the third bin by counting the occurrences of the number 3 in the bin index vector, bin. MATLAB supports plotting histogram feature that enables the user to create a bar graph for any vector or matrix and grouping the data into bins using an automatic binning algorithm.

It isn't a function to download by itself, it is just part of newer Matlab versions since R2014b so unless you upgrade to that version or later just ignore it. 2011-07-11 This MATLAB function returns 2-D grid coordinates based on the coordinates contained in vectors x and y.
