Hi,

I created a bar chart in xl2007. I can click anywhere on the chart and I get
the chart Tools (3 extra ribbons) displayed (Design, Layout and Format).

I click on Layout ribbon and I see Error Bars in the Analysis block.

I click on Error Bars and I get a drop down with the 5 options (None, Error
bars with standard error, Error bars with percentage, Error bars with
standard deviation and More Error bar options.

Clicking on More error bar options allows the series to be selected and
after selecting the series, all the error bar display options come up.

Is the above what you are doing? Because if it is then I am afraid I do not
know what the problem is.

Regards,

OssieMac

In excel 2007 I want to compare to series in bar graphs. I want to put error
bars on the graph. The series values are averages of multiple numbers and
standard deviations and standard errors of means are easily calculated. When
go to format selection, select my series and then click on the layout tab,
I see the "Error bars" control, but it is faded out as if it is inactive.

How do I activate this function so that I can add error bars to my graph?
Does the data have to be entered in a specific manner in order to generate
error bars?
