#! To display them correctly you need to define symbols for them in
#! MetaPost languge the same way as ordinary symbols are usually  
redefined.
#!
#! Firstly point symbol. In the


layout m
#!CODE
code metapost
#!ENDCODE

   path bat_path_x;
bat_path_bb) - (xpart llcorner bat_path_bb))) rotated 210;

#! section of your layout define point u:bat symbol like this
#!CODE
def p_u_bat(expr pos, theta, sc, al) =
enddef;
#!ENDCODE

#! similarly the line u:bat symbol
#!CODE
def l_u_bat(expr P) =
enddef;
#!ENDCODE

#! and finally the area u:bat symbol (pattern in this case)
#!CODE
% bat pattern
endpattern;

% bat area symbol
def a_u_bat (expr Path) =
enddef;
#!ENDCODE

#! These symbols will be included also in the legend. To
#! change the way how they are drawn there just define appropriate
#! macro. Its name should be symbol macro name with <code>_legend</code>
#! suffix.
#!CODE
def l_u_bat_legend =
enddef;
#!ENDCODE

code tex-map
\legendcontent={%
   \hsize=\legendwidth
   \color[0 0 0]\the\legendtextcolor
   \formattedlegend
   \color[0 0 0]
}

legend-width 8 cm

endcode

endlayout

#! Finally, add description of your new symbols that will be shown
#! in the legend using <code>text</code> command anywhere
#! in the configuration file.
#!CODE
text en "point u:bat" "bat"
text en "line u:bat" "bat path"
text en "area u:bat" "lot of bats"
#!ENDCODE

#! After all these definitions you receive bat point, line and area  
symbols
#! with proper graphical representation and legend boxes.
