Description Matthew Truch 2005-04-14 02:29:02 UTC 
Version:           1.1.0_devel (using KDE KDE 3.3.0)
Installed from:    RedHat RPMs
OS:                Linux

Create an equation that depends on a static vector.  Plot said equation.  Edit the static vector's range.  The plot will not update to reflect the change.  However, if you force an update (for example, by opening that equations 'edit equation' dialog and then just clicking ok (don't change anything)) then the plot does update.

CVS commit by staikos: 

make s-vectors update properly - the base class assumes that nothing really
changed since the derived classes typically "update"
