           Summary: ability to operate only on what is visible shown in plot
           Product: kst
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: kst kde org
        ReportedBy: netterfield astro utoronto ca


Version:           0.99-devel (using KDE 3.2 BRANCH >= 20040204, Mandrake Linux Cooker i586 - Cooker)
Compiler:          gcc version 3.3.2 (Mandrake Linux 10.0 3.3.2-6mdk)
OS:                Linux (i686) release 2.6.2-3mdk

It would be good to come up with a way to (optionally) operate only on points which are currently visible in a plot, rather than acting on the whole vector - this could be useful in:

-fitting to an even in the data
-getting the psd of a subset of data
-getting statistics or histograms of a subset of data.
