Standard deviations in Excel Charts

Does anyone know how to creat a line chart in Excel in which each data point
has its own standard deviation value? I need to enter them without
calculating them from the spreadsheet. Excel will only let me have one
standard deviation value for all data points. Any thoughts?

Hi Marina -

You have X and Y in adjacent columns. Put the SD values in the next column. Plot the
points. Format the points to bring up the Y Error Bar dialog. Choose Custom, and for
the + and - error bar values, use the range containing the SD values in the
worksheet. All you need to do is click in the edit box, then select the cells with
the mouse.

As Jon pointed out indirectly, you cannot. To use a different value
for each point, you have to use the Custom option and that works only
with a worksheet range; it ignores a named formula Of course, you
can always hide the worksheet range where you calculate these values.
