[MP] labels of points on a circle

[MP] labels of points on a circle

[dalyoung]

Hi all,

To draw 9 points with labels, I used the following code.

\startbuffer[point2]
path p;
numeric i; i=1;
for j =0.5,1.3,2.5,3,4,4.8,6,7.2,7.9:
z[i] = dir(j*45) scaled 4cm;
i:= i+1;
endfor;
p := z1..z2..z3..z4..z5..z6..z7..z8..z9..cycle;
draw p;
drawpoints p;
drawpointlabels p;
\stopbuffer
\placefigure[middle][]{}{\processMPbuffer[point2]}

Then it draw everything well except writing labels inside the circle.  
How can I write the labels of the  points outside of the circle?

I'd like to draw 9 points randomly on a circle. Is there a nice way to  
do it?

Thank you.

Best regards,

Dalyoung

Hi Dalyoung,

You can try to adapt the following snippet:

numeric i;
pickup pencircle scaled 4pt;
for i = 1 upto 10:
	z[i] = dir(uniformdeviate 360);
	drawdot z[i] scaled 4cm;
	label(decimal(i), z[i] scaled 4.3cm);
endfor;

Best regards,
Bostjan
