14<code><pre>
15<b>loglogpn</b>(...) is the same as LOGLOG(...), except that the Y data
16may have positive and negative values. This is useful to detect
17unexpected negative values in the Y data (causing repeated 'Negative
18data ignored' warnings), or to visualize the magnitude of an
19oscillating signal in log scale.
20 
21<b>loglogpn</b>(X,Y) plots X versus Y in log-log scale, where Y may have
22positive and negative values. By default, negative values are ploted
23with dashed lines and positive values with full lines. If X is not
24specified, Y is plotted versus its index.
25 
26<b>loglogpn</b>(X,Y,LineSpecPos,LineSpecNeg) specifies LineSpecPos and
27LineSpecNeg for the line types, marker symbols and colors for the
28positive and negative values of Y. For instance,
29<b>loglogpn</b>(X,Y,'ro-','b*') plots the positive Y with red line and 'o'
30markers and the negative Y with blue stars '*'. If only LineSpecPos
31is specified, the same is taken for LineSpecNeg, with a different
32LineStyle.
33 
34<b>loglogpn</b>(X,Y,LineSpecPos,LineSpecNeg,'PropertyName',PropertyValue,...)
35sets property values for all lineseries graphics objects created by
36<b>loglogpn</b>. See the line reference page for more information.
37 
38[HP, HN] = <b>loglogpn</b>(...) returns the handles to the two lineseries
39graphics objects.
