Re: error while displaying a line

["Dr. Roland Bock" <box2OO6 eudoxos de>]

Hi,

you are probably calling gtk_databox_auto_rescale?

That function calculates

(Pixel_max - Pixel_min)/(Value_max - Value_min)

This fails for a line parallel to the x axis (and would also fail for a 
line parallel to the y axis).

Of course it would be possible to "guess" a useful data range. The 
question is: What is the right heuristic, which seems natural for 
viewers at different values?

Solutions are welcome :-)


Regards,

Roland
