All,
I am wondering why my dots are not filled with the drawdot command.
\startuseMPgraphic{yeqx2}
%define function
vardef f(expr x)=
x*x
enddef;
%define clipping path
path cpath;
cpath:=(-5,-5)--(5,-5)--(5,5)--(-5,5)--cycle;
%create function path
path p; p:=(-5,f(-5));
for x=-5 step .1 until 5:
p:=p--(x,f(x));
endfor;
p:=p--(5,f(5));
%clip function path to clipping path
p:=p cutbefore cpath;
p:=reverse p;
p:=p cutbefore cpath;
%initialize scale
numeric u; 10u=2in;
%draw the grid
for k=-5u step 1u until 5u:
draw (k,-5u)--(k,5u) withcolor 0.85white;
draw (-5u,k)--(5u,k) withcolor 0.85white;
endfor;
%draw axes
drawdblarrow (-5.2u,0)--(5.2u,0);
drawdblarrow (0,-5.2u)--(0,5.2u);
%label axes
label.rt(btex $x$ etex, (5.2u,0));
label.top(btex $y$ etex, (0,5.2u));
label.bot(btex $5$ etex, (5u,0));
label.lft(btex $5$ etex, (0,5u));
%scale function path
p:=p scaled u;
%draw function path
drawdblarrow p withcolor blue;
%draw plotted points
for x=-2 step 1 until 2:
drawdot ((x,f(x)) scaled u) withpen pencircle scaled 4pt;
endfor;

Works for me. (-2,4), (-1,1), (0,0), (1,1) and (2,4) are black
dots on a blue line. tex&pdf files mailed separately.

Look more closely. The dots are not filled.

As an alternative, replace the drawdot command with the draw command.
Then the dots fill.

I assure you that I see them filled, in Acroread, as well
as in xpdf. I'll send you a screenshot. :-)

Aha!
In Previewer on my Mac, the dots are not filled. But when I open the
same document in Acrobat Professional, they're filled!
Thanks.
