Version: 0.99devel (using KDE KDE 3.2.1) Installed from: RedHat RPMs OS: Linux vectors which are created as a result of a linefit (or other ways) are only two point vectors, and therefore display incorrectly when either (or both) of the axes are logarithmic.
I'm not able to reproduce this one. Can you provide a testcase?
Well, it's more of a fundamental flaw in the linefit results than a display bug. The problem is that a staight line looks curved in a log plot, so if you plot some data and fit a line to it, and are in a log plot, the line fit should look curved. But since kst connects points of a vector with straight (even in log plots) lines, it becomes a problem when the points of a vector are too far apart.
Indeed, the linefit is no good for log plots. However we could easily fix this by adding an optional parameter to indicate the "resolution" of the fit. I doubt it's worth the effort though, since we have real fits now. that linefit plugin was really just a demo. Anyone?
This is not the proper plugin to use for industrial-strength fitting procedures.
