Hi,
I am trying to learn Metapost using Context. I tried a few examples
for drawing
things and they worked well. But the "show" command does not seem to
work. For
example, the code
\startuseMPgraphic{GridDots}
u=1cm;
pickup pencircle scaled 8pt
for i = 0 upto 2:
for j = 0 upto 2: draw (i*u,j*u); endfor
endfor
\stopuseMPgraphic
\useMPgraphic{GridDots}
from John Hobby's manual works great.
However, the following code gives no output in the PDF file. Am I doing
something wrong?
\startuseMPgraphic{LinearEq}
a+b = 2a - b = 3;
show a,b;
\stopuseMPgraphic
\useMPgraphic{LinearEq}
I am using the following version from Texlive
ConTeXt ver: 2008.05.21 15:21 MKII fmt: 2008.10.1 int: english/english
The output of show goes to the terminal and the log file. Look for the
values in filename-mpgraph.log.
\ctxlua{metapost.showlog = true}
