This is my overloaded symbol for gradient point. I want to make a line symbol
for gradient but I havent gotten around to it.
code metapost
def p_gradient_AMER (expr pos,theta,sc,al) =
U:=(.15u, .4u);
T:=identity aligned al rotated theta scaled sc shifted pos;
pickup PenC;
#Left Hand side
thdraw (-.3u, -.2u) -- (-.7u, .1u);
thdraw (-.2u, -.1u) -- (-.4u, .6u);
#Centerline
thdraw (0u, 0u) -- (0u, .9u);
#Right side
thdraw (.3u, -.2u) -- (.7u, .1u);
thdraw (.2u, -.1u) -- (.4u, .6u);
enddef;
initsymbol ("p_gradient_AMER");
endcode
