Hi Johan Wendelstam,
Thank you for updating us.
Kindly create separate incidents from DirectTrac for the below reported issues. This will help us to have a regular follow-up.
Currently we don't have the support to set colors on chart series if the property "InvertIfNegative" is enabled. We request you to create an incident for the same, requesting the support. We have to log a feature request on the same to have a regular follow-up.
Also, we will get back to you on exposing the property "InvertIfNegative" with further details in two business days (i.e., July 11, 2012).
Thanks and Regards,
Rajesh A.
