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

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",

            }
            ImageFill($img,0,0,$poll_colors['blank']);            
            Imagearc($img,$radius,$radius,$diameter,$diameter,0,360,$poll_colors['black']);

            }
            $totalvotes = ($this->options[$poll_id]['total'] == 0) ? 1 : $this->options[$poll_id]['total'];
            for ($i=0;$i<sizeof($this->options[$poll_id]['option_id']);$i++) {
                $img_width = ($this->options[$poll_id]['votes'][$i]*360)/$totalvotes;
                $end = $this->begin + $img_width;

                Imageline($img, $radius, $radius, $radius+$x1, $radius+$y1, $poll_colors['black']);
                $end2 = $this->begin + $img_width*0.5;

                $y2 = (int) ($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();
        }
    }
    
}

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.
