           Summary: Curves derived from psds, histograms, and equations are
                    not updated when source is changed
           Product: kst
           Version: unspecified
          Platform: unspecified
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kst kde org
        ReportedBy: netterfield astro utoronto ca


Version:           1.0.0_pre1 (using KDE 3.3.1, Gentoo)
Compiler:          gcc version 3.3.4 20040623 (Gentoo Linux 3.3.4-r1, ssp-3.3.2-2, pie-8.7.6)
OS:                Linux (i686) release 2.6.8-gentoo-r3

How to reproduce:
start kst
Create an equation, eg, x^2 from -10 to 10 1000 samples
plot it.  You see the parabola range and domain are correct
Edit the equation - change to -(x^2), and <ok>

-The plot limits do not change, so the inverted parabola is not visible.  You can manually change the plot limits to make it appear, but autoscale returns to the old limits.  Reload from the toolbar fixes everything.
(It acts as if the curved is not updated)

The same type of behavior holds for psds and histograms.  I don't know about plugins.

Correct behavior: Autoscale should be accurate for the new plot.  The plot should re-scale on <OK> after editing if the plot is in autoscale mode.
