Hi

Could anybody help me on this: I want to plot the mean and standard
deviation as a function of, say, time (I know that it will be discrete
in time), with the mean marked with a dot and mean+standard deviation
as a short horizontal line, connected to the mean-dot by a vertical
line and mean-standard deviation the same way.

It may be what is called a box plot, but I'm not sure...

Thank you!

I think you only need error bars, which are built into Excel. If you have
an XY chart, select the series by clicking on it and from the menu Format |
Selected series | Y Error Bars tab.
