Adv poll : color of the bars

bobdeo — GMT

Hi !

I try to add / change the colors of the bars... Do you know where I can find that ?

Is it possible to cancel the effect on the bars (colour scale) ?

Thanks in advance

ok ! I found this file (class_pgfx.php)

[code] /**

* Advanced Poll 2.0.3 (PHP/MySQL)

*/

class pgfx extends poll {

var $colors;
var $begin;

function pgfx() {
$this->begin = 0;
$this->poll();
$this->colors = array(
"aqua" => "145,187,234",
"blue" => "73,96,214",
"brown" => "176,112,86",
"darkgreen" => "18,117,53",
"gold" => "220,170,75",
"green" => "30,191,56",
"grey" => "207,188,192",
"orange" => "240,131,77",
"pink" => "244,109,188",
"purple" => "149,57,214",
"red" => "205,31,119",
"yellow" => "240,213,67",
"blank" => "255,255,255",
"black" => "0,0,0"
);
}

function output_png($poll_id,$radius) {
if ($radius < 20) {
$radius = 90;
}
$diameter = $radius*2;
$img_size = $diameter+2;
if ($this->is_valid_poll_id($poll_id)) {
$img = ImageCreate($img_size, $img_size);
for(reset($this->colors); $key=key($this->colors); next($this->colors)) {
eval("\$poll_colors[\$key]=ImageColorAllocate(\$img,".$this->colors[$key].");");
}
ImageFill($img,0,0,$poll_colors['blank']);
Imagearc($img,$radius,$radius,$diameter,$diameter,0,360,$poll_colors['black']);
if (!isset($this->options[$poll_id])) {
$this->get_poll_data($poll_id);
}
$totalvotes = ($this->options[$poll_id]['total'] == 0) ? 1 : $this->options[$poll_id]['total'];
for ($i=0;$ioptions[$poll_id]['option_id']);$i++) {
$img_width = ($this->options[$poll_id]['votes'][$i]*360)/$totalvotes;
$end = $this->begin + $img_width;
$y1 = sin($end/180*M_PI)*$radius;
$x1 = cos($end/180*M_PI)*$radius;
Imageline($img, $radius, $radius, $radius+$x1, $radius+$y1, $poll_colors['black']);
$end2 = $this->begin + $img_width*0.5;
$x2 = (int) ($radius+cos($end2/180*M_PI)*15);
$y2 = (int) ($radius+sin($end2/180*M_PI)*15);
Imagefilltoborder($img,$x2,$y2, $poll_colors['black'], $poll_colors[$this->options[$poll_id]['color'][$i]]);
$this->begin += $img_width;
}
$this->begin = 0;
ImageColorTransparent($img,$poll_colors['blank']);
ImagePNG($img);
} else {
$loc = "$pollvars[base_url]/image/error.png";
header("Location: $loc");
exit();
}
}

}

?>[/code]

... I just need help to cancel the effect on the bars (colour scale)...

Thanks !

if you want them to be a solid color go to the images folder and replace them with ones without gradients. Those color codes are in that file and another one i think, there's not really much point editing it if you don't know how to add the extra color optoins in completely.
