XL: ErrorBar Method Fails Adding Negative Custom Error
Last reviewed: September 13, 1996

Article ID: Q117174

The information in this article applies to:


 * Microsoft Excel for Windows 95, versions 7.0, 7.0a
 * Microsoft Excel for Windows, versions 5.0, 5.0c
 * Microsoft Excel for the Macintosh, versions 5.0, 5.0a

SYMPTOMS
In Microsoft Excel, when you run a Visual Basic macro that uses the ErrorBar method to add error bars to a series on a chart, you receive the following error message when you run the macro:

Run-time error '1004':

ErrorBar method of Series class failed

CAUSE
This error occurs when the macro uses the ErrorBar method to add only a negative custom error amount to a selected series, and the Amount argument is missing.

Note that when you turn on the macro recorder, and you use the Format Data Series dialog box to add only a negative custom error amount to a chart series, the recorded macro is missing the Amount argument and returns the error message above when you run the macro.

The Amount argument should be optional for the ErrorBar method, as the Visual Basic Reference indicates. The argument is used for the positive error amount when you use a custom error amount. However, the argument is required if you want to avoid receiving the error message above, even if the value is empty when you use the ErrorBar method to add a negative custom error amount.

WORKAROUND
To avoid receiving this error message when you use the ErrorBar method to add only a custom minus error bar to a chart series, add the following argument to the ErrorBar method command in your macro:

Amount:="" For example, to add a custom minus error bar with the value 3 to series four on the active chart, use the following command:

ActiveChart.SeriesCollection(4).ErrorBar Direction:=xlY, Include:= _ xlMinusValues, Type:=xlCustom, MinusValues:="={3}", Amount:="" Note that if you turn on the macro recorder, and you use the Error Bars dialog box to add only a negative custom error amount to a chart series, the recorded macro contains the Amount argument, and you do not receive the error message when you run the macro.
