回答： Shreedhar Todkar 2016-7-8

Hello everybody,

I have 36 values of mean and their standard deviation. 12 values falls between 38 to 45, another 12 values falls between 53 to 60 and another 12 values fall between70 to 75. I just want to show in a graph clearly the mean values and their standard deviation. I tried so many but none of them are really clear bcoz, I have values like 43.77, 43.10, 43.5... some close values.. how can I do that.. help me

You can use errorbar:

% The data

Y = [rand(12,1)*7 + 35; rand(12,1)*7 + 53; rand(12,1)*5 + 70];

% The standard deviations

E = rand(36,1)*10 + 3;

% Mean values with error bars

errorbar(Y,E,'x')

I already this, boxplot also plays good role but finally decided to go ahead with Errorbar.. so I accept your answer, since I used the error plot for my values.. Thank you

boxplot, barplot with error bars, you can plot a histogram of the values, there are lot of ways to plot the data. Which plot type is best is usually a function of the type of data you are plotting

com'on i know the plot. plz read the question once agian, I asked you in what way i can show it clearly

"I just want to show a graph."

How can plot not show the graph? Please be more specific with what you want. You kind of gave us sample data and said you wanted to plot it. We don't know anything else. Perhaps find a picture on google images that shows it or something to help us along.
