Hi, Milton.
Not without changing TeeChart source code. To be more specific, you'd have to change the TBarSeries.DrawBar method and rotate arrow (when you're plotting negative value).
Perhaps this is something we could add as feature in next maintenance release. In case you have TeeChart v7 source code license, please contact me at "marjan at steema dot com" and I'll send you modified code which draws rotated arrows,cones, etc.. when value is negative.

hi,
I do own a source code license. I sent you an e-mail. I also tried to make the change myself but I realised that it might be bigger than I antecipated, and also it would be best if I keep my source code in sinc with yours, so that when a new version comes out I won't lose this modification.
best regards,
Milton Lapido.
