Hi Harufumi, Plotting downwards is not implemented. Support for this feature could be implemented for simple cases (TGraph or TH1) However, objects of these types with error bars and associated functions, annotations, log scales, etc would be more complex to support. The only solution that I see is to have this logic at the TPad level, but it would have side-effects for the annotations.
