Error bar for a set of values

y=[53.3654 16.6489 40.9854 21.7873];

error=[7.3822 4.1028 5.1562 1.2531];

Need to plot bar graph with the error bars corresponding to the values in error.

Hi Viswajit,

You could achieve this using the functions bar to create a bar graph and errorbar to add the error bars. Here is how you can achieve it:

y = [53.3654 16.6489 40.9854 21.7873];
error = [7.3822 4.1028 5.1562 1.2531];

bar(y)
hold on
numBars = numel(y);
x = 1:numBars;
errorbar(x, y, error, '.')

Please refer to the following MathWorks documentation for more information on:

• errorbar - https://www.mathworks.com/help/matlab/ref/errorbar.html
