unable to draw


I've been trying to use the draw()-functions of Cindyscript. Nothing I try seems t o work, however. I ended up copying and pasting the example from the manual

sizes=1..15;
forall(sizes,
pointsize(#);
textsize(#+4);
draw((#,0));
drawtext((#,1),#);
)

into the 'Shell'-area of the script editor. Shift-entering results in an empty out1 message, but nothing is shown in the drawing area.

Typing in by hand the instruction

drawpoly([0,0],[1,0],[0,1])

(as shown in the manuals, but without any modifiers) results in the message

in [3]= drawpoly([0,0],[1,0],[0,1])

WARNING:Unknown function: drawpoly
out[3]= ___

What am I doing wrong?

Dirk,

please try to use these command in the "draw" section of the script. Otherwise, you will not be able to see their results (it's shown and immediately cleared).

That works just fine, thank you.

B.t.w., the error in the "drawpoly"-function is just a stupid syntax error I made. Drawpoly expects a LIST as its single argument, in stead of each vertex point as a separate argument.

I notice that the forum software (on my computer at least) filters out the square brackets from my input text. As far as I can see I have correctly entered all square brackets.

Yes, it does filter them out — you have to write a double open bracket. Otherwise you create a link into our wiki.
