Version: (using KDE KDE 3.5.4) Installed from: Ubuntu Packages OS: Linux When I have kmplot draw a function graph (no matter what complexity) and use any kind of zooming function (in/out/whatever), then kmplot hangs, I see the mouse pointer that tells me to wait ("hour glass" in other operating systems) and so it remains, i.e. the window gets blank and I can't do anything in it. It might be that it is no kmplot bug, since - if I remember right - I once was looking in the source for finding the bug and it seems that the corresponding function is never called at all.
also it happens to me, with Kubuntu Edgy RC1
This happens to me, too. Kubuntu Edgy 6.10
OK, I think I've managed to track down what is going on. It seems that the Parser::eval() method doesn't handle decimal numbers correctly, but returns 0 instead. This leads to xmin and xmax both becoming 0 in coordToMinMax(), which in turn makes dx in plotfkt() to be 0 as well, so the rendering gets stuck in an endless loop. Hope that will help. /John
I can not reproduce this bug at all with kmplot 1.2.0 on KDE 3.5.7 (openSUSE packages), so I assume it's fixed. Please retest with a more recent version and reopen this bug, if kmplot still hangs on zooming, thanks.
