Есть код горизонтальной гистограммы, что необходимо изменить в коде, чтобы гистограмма стала вертикальной. Перепробовал уйма способов ничего не получается. Подскажите, пожалуйста, очень нужно.
$width=500;
$left_margin = 50;

$small_size =12;
$text_indent = 10;
$x =$left_margin + 60;
$y = 50; //то же
$bar_unit = ($width - ($x + $right_margin))/100;
$height = $num_object*($bar_height + $bar_spacing)+50;

$im = ImageCreateTrueColor ($width, $height);

$white = ImageColorAllocate ($im, 255, 255, 255);

ImageRectangle ($im, 0, 0, $width-1, $height-1, $line_color);

//Вывод чисел
