How can I plot mean +/- 1 standard deviation for every data point in my dataset ?

I have a dataset of 15 data points. And I calculated mean(dataset) + 1*standard value(dataset) ,mean(dataset) - 1*standard value(dataset). I would like to plot these values as error bars for every data point in the data set. Please let me know how do it do it?

Thanks
