[NTG-context] for loop not working in metapost

30 Aug 2024

      Hi,

I have plotted a log function and I want to draw an xy axis grid.
Below is the code

\starttext
\startMPcode
draw function(1,"x", "log(x)", .1, 10, .01) scaled 1cm;
for i = 0 upto 10:
   draw (i*cm, -5cm) -- (i*cm, 5cm) dashed;
endfor;
for i = -5 upto 5:
   draw (0, i*cm) -- (10cm, i*cm) dashed;
endfor;
\stopMPcode
\stoptext

My first for loop draws lines but the second gives me an error. Please help.
