1. Is the result in the formula cell what you expect? You must have two or more number arguments if you are using any of the STDEV* functions or the function returns a 0 which would not show error bars. In the provided example, you couldn’t just drop a standard deviation calculation into cell b4, for example, as it only includes one piece of sample data.

2. Is the scale of the chart causing a problem? For example: do you have a very large number in your column and a very small margin of error? If your column represents 100,000,000 and your error is only 10, then the error bar would be very small in comparison and could look like it’s either missing or the same as the other bars. If your missing error bar shows as just a black line at the top of the column, this might be the case.

]]>I followed your example where I selected a range B4:E4 cell range for both positive and negative error values. These cells contain a formula that calculates the error value based on a margin of error that is unique to each type of value. The resulting error bars, should be unique to each bar in the chart.

But when I select the range for both positive and negative values. The result is either no error bars on the chart or similar error bars for each value. Please help feeling frustrated.

]]>In the example below, A1 and B1 contain date/times.

C1 contains “=B1-A1” and the answer is 3.81 days (the default format is days)

D1 contains “=C1*24” which gives the same answer in hours. (24 hour days)

If you wanted that answer in minutes you could say “=C1*24*60” ]]>

We must use two IF() functions – one nested within another.

In English, the nested IF(), above would read:

“If cell A2 is ‘EXPRESS MILES’, then the answer is 0.2 or else, if cell A2 is ‘REWARDS’, then the answer is 0.2 or else, the answer is 0.”

0.2 is, of course, 20%

Because they are nested, the IF()s are evaluated one at a time, in sequence, from left to right.

If both are false (neither ‘EXPRESS MILES’ nor ‘REWARDS’ is true) then zero is the answer for that cell.

Thank you for the explanation, I changed the Calculation option to Automatic and problem solved! ]]>
