protected double <A HREF="../../../../src-html/org/jfree/chart/axis/LogarithmicAxis.html#line.316"><B>switchedLog10</B></A>(double&nbsp;val)</PRE>
<DL>
<DD>Returns the log10 value, depending on if values between 0 and
 1 are being plotted.  If negative values are not allowed and
 the lower bound is between 0 and 10 then a normal log is
 returned; otherwise the returned value is adjusted if the
 given value is less than 10.
<P>

<DT><B>Parameters:</B><DD><CODE>val</CODE> - the value.

public double <A HREF="../../../../src-html/org/jfree/chart/axis/LogarithmicAxis.html#line.333"><B>adjustedLog10</B></A>(double&nbsp;val)</PRE>
<DL>
<DD>Returns an adjusted log10 value for graphing purposes.  The first
 adjustment is that negative values are changed to positive during
 the calculations, and then the answer is negated at the end.  The
 second is that, for values less than 10, an increasingly large
 (0 to 1) scaling factor is added such that at 0 the value is
 adjusted to 1, resulting in a returned result of 0.
<P>
<DD><DL>
<DT><B>Parameters:</B><DD><CODE>val</CODE> - value for which log10 should be calculated.

 not greater than the argument, is equal to a mathematical integer and
 satisfying the condition that log base 10 of the value is an integer
 (i.e., the value returned will be a power of 10: 1, 10, 100, 1000, etc.).
