Zoom limits and zoom errors : test it yourself
Red
I have test scilab 5.1 on three different graphic Cards all DRI
capable :
Intel GM45 Express
NVIDIA Quadro FX 3800
NVIDIA GeForce 9600 GT
Only intel GM45 Express usecanvas(%F) is not set by default so have
manually set it.
On these three graphic Cards repetitive zooms lead to bad graph frame
and curves getting out the graph frame.
On 5.2-beta it even leads to a blank figure...
I see nothing have been done to correct this and it's been a while i'm
posting.
There was a bug in zoom_box which seems to have been resolved..
(bug date : Tue, 27 Jan 2009 08:14:19 +0000 (09:14 +0100))
Please consider trying on your own the next test.. whatever your
hardware and version is:
// Bring up the plot demonstration
> plot()
// Then zoom until you get 10^-7 precision on one of the axis at
least. This means zooming with thin rectangles.
// And observe what's happening.
I guess there should be a zoom limit to avoid this kind of problem.
Good luck trying,
Best regards,

Yes, I see what you mean.
Scicoslab does not suffer from this drawback.
