  Engauge Digitizer - Fixing The Axis Points</H2>
<HR WIDTH="100%">
<P>If you are seeing unexpected values for the coordinates produced by 
Engauge Digitizer, then there probably is a problem with the axis 
points. Axis point problems include:</P>
<UL>
<LI>An axis point was placed at the wrong location on the graph</LI>
<LI>The X or Y coordinate of an axis point was entered incorrectly</LI>
<LI>In a polar plot, the origin has a nonzero radius (so the default value of zero
in the <A HREF="dlgcoordsys.html">Coordinates Dialog</A> does not apply)</LI>
</UL>
<P>The Axes Checker usually reveals problems with axis points - a shape that 
is not a rectangle (in cartesian coordinates) or annular disk (in polar coordinates)
is usually a symptom.</P>
<P ALIGN="center"><IMG SRC="fixingaxispoints.png" ALT="Picture of slanted grid lines"></P>
<P>This trick is also helpful if your axis points are fine, but the problem 
lies in the original image.</P>
