Mojca and Peter, thanks very much for your responses. I used Peter's
solution and it worked beautifully.
Does anyone know how I can change the size of these labels? If I try
textext(\tfa decimal(tx))
that does not work.

Hi,
I want the labels as (0.5,0.55,0.6,0.65,0.7,...,1) or (0.50,0.55,0.60,0.65,0.70,...,1). Either of these two is fine.
I tried the following code for this.
\starttext
\startuseMPgraphic{labeltest} numeric rmin,rmax; rmin := 0.5; rmax := 1; ux := 25cm; uy :=10cm; % draw axes draw (rmin,0)*ux -- (rmax+0.1,0)*ux; draw (rmin,0)*ux -- (rmin*ux,(1.1)*uy); for x = 0.5 step 0.05 until 1.1: label.bot(textext(decimal(x)),(x*ux,x*uy));
you accumulate the rounding error with every step of the loop. try to avoid such 'low value' steps if possible.
for x = 10 step 1 until 22: % 0.05*20 to get an integer loop index tx := x/20; % correct value label.bot(textext(decimal(tx)),(tx*ux,tx*uy));
Best wishes, Peter
endfor;
\stopuseMPgraphic
\useMPgraphic{labeltest}
\stoptext
I get (0.5,0.55, 0.6,0.65001,0.70001,0.75002,...,1.00003) instead. I don't understand why I get more than 2 digits after 0.6. Is there a way to restrict the number of digits after the decimal point. Thanks very much.
