Re: strange behavior...

Hi Zeev,

the message is given, if the vertical or horizontal latitude of your the 
limits you set is zero. In such a case, the widget cannot reasonably 
derive pixel coordinates from data values (maybe it could perform an 
educated guess, but that is not implemented today).

Thus, if you start with a line, you should use 
gtk_databox_set_total_limits instead of ...auto_rescale.

Regards,

Roland
