The warning appears if any of the values in Format axis, Scale Tab has a
value of 0.
To be able to change the value from 0 to 1 you must select *the other axis*
(the one without problems) and select the "Scale" tab... When you open
*again* the axis with problems you will be in the "Scale" tab of the
problematic axis and you'll be able to change the offending value...
