H = pareto(...)
[H,ax] = pareto(...)


Pareto charts display the values in the vector Y as bars drawn in descending order. Values in Y must be nonnegative and not include NaNs. Only the first 95% of the cumulative distribution is displayed.

pareto(Y) labels each bar with its element index in Y and also plots a line displaying the cumulative sum of Y.

pareto(Y,names) labels each bar with the associated text in the matrix or cell array names.

pareto(Y,X) labels each bar with the associated value from X.

pareto(ax,..) plots into the axes ax rather than the current axes, gca.

H = pareto(...) returns the primitive Line and Bar objects created.

[H,ax] = pareto(...) additionally returns the two axes objects created.

Create a Pareto chart of vector y.

y = [90,75,30,60,5,40,40,5];

pareto displays the elements in y as bars in descending order and labels each bar with its index in y. Since pareto displays only the first 95% of the cumulative distribution, some elements in y are not displayed.

Examine the cumulative productivity of a group of programmers to see how normal its distribution is. Label each bar with the name of the programmer.

codelines = [200 120 555 608 1024 101 57 687];
coders = {'Fred','Ginger','Norman','Max','Julia','Wally','Heidi','Pat'};

pareto(codelines, coders)
title('Lines of Code by Programmer')


You cannot place datatips (use the Datacursor tool) on graphs created with pareto.
