MS Graph, while similar to XL, doesn't support the full capabilities of
XL. Custom error bars is one of the features supported by XL but not
by Graph.

Hello NG,

from a Visual Basic (6) project, I need to customize the error bar of a
chart, to get a different value for each data point.

In Excel, this is done with a range reference:

ActiveChart.SeriesCollection(1).ErrorBar Direction:=xlY, Include:= _
xlPlusValues, Type:=xlCustom, Amount:="=Hoja1!R1C3:R2C3"

but I need to do this by VB code, in order to control a OLE-Chart.
Reference to the datasheet-range is not working:

oGraph.SeriesCollection(1).ErrorBar Direction:=xlY, Include:=xlBoth, _
Type:=xlCustom, Amount:=oGraph.Application.DataSheet.Range("A1:A3" )

Any ideas?

Thanks in advance

Miguel
