hi John,

we must add these two arguments

Amount Optional Variant. Amount of the error. Used only for the amount of a positive error
when Type is set xlErrorBarTypeCustom.

MinusValues €‹€‹Optional Variant. Amount of negative error
when Type is set xlErrorBarTypeCustom.

..ErrorBar Direction:=xlY, Include:=xlErrorBarIncludeBoth, Type:=xlErrorBarTypeCustom, Amount:=1, MinusValues:=-5

Dear All,

I am trying to use following code to create a bar chart with error
bar. But " .ErrorBar Direction:=xlY, Include:=xlBoth,
Type:=xlCustom, Amount:=errBar" doesn't work.

Could anyone help me figure out how to handle this?

Thanks

John
