This is a fabulous project, but I am dearly missing the possibility to add y error bars to a second plot/data series, which is associated with a second y axis (on the right).
It would be great if this could be added, because it would replace another commercial package I am currently using.
This feature already exists, but it is not an automated task.
The errors associated with a curve are treated as another curve in SciDAVis (1).
Then, in the same way you attached a curve from left to right axis, you must attach the associated errors "curve" to the right axis too.
(1) I'm not sure if this is a feature or a bug. Anyway, feature request #107 could be changed to: when changing the axis of a curve, automatically attach the associated errors to the corresponding axis.
