GML any idea how can i make a dynamic circle [SOFT] diagram ? [SOLVED]

[Kasra]

any idea how can i make a circle diagram like image below ?

this kind of diagram help me draw more simple and efficient GUI for android. tnx
i have some codes about drawing some line with same distance to center like fractal, but i think there is better way

i write a code like below in my circle_diagram object:

//**START OF THE CREATE EVENT**//
//****ATTRIBUTES*****//
radious       = 128;
split_number  = 48; // 75% IS FULLED
split_module  = 64;
diagram_colour= c_red;
diagram_width = 5;
diagram_alpha = 1;
base_degree   = 90;
//****ATTRIBUTES*****//
//*******************//
//*****CONSTANTS*****//
p             = 3.1415;
perimeter     = 2*p*radious;
split_lenght  = perimeter / split_module;
split_degree  = 360       / split_module;
//*****CONSTANTS*****//
//***END OF THE CREATE EVENT***//
//*****************************//
//***SATRT OF THE DRAW EVENT***//
//THIS VAR WILL RESET AS THE EVENT END'S
var doff = base_degree;

for(var i = 0; i < split_number; i++)
{
    var lx_1, ly_1, lx_2, ly_2;
    // line_x&y_coordinates
    lx_1 = dcos(doff)*radious + x;
    ly_1 =-dsin(doff)*radious + y;
    doff+= split_degree;
    // update x_2 & y_2
    lx_2 = dcos(doff)*radious + x;
    ly_2 =-dsin(doff)*radious + y;
    draw_set_alpha(diagram_alpha);
    draw_line_width_colour(lx_1, ly_1, lx_2, ly_2, diagram_width, diagram_colour, diagram_colour);
    draw_set_alpha(diagram_alpha);
}
//***END OF THE DRAW EVENT ****//

this works, but it is so basic and edges are not soft, on android devices it look very bad, so how can i found a better way for this ?
(i need this diagram for show my ammo, [exactly like ldoe game])

In a word, basically like this.

In a word, basically like this.

yep that algorithm in the link worked like a charm !, it will looks soft only if i remove draw_line_width and replace drawing line code [in width 1] like image below, tnx

Yeah, Dave stuff is really solid, you should bookmark that and check it out from the home page up if you're not familiar with it!
