rotating text and putting on a bar chart

[Gazz1982]

Hi again, I have a bar chart, standard 3 verticle bars coloured differently, but now i want to put some text on them, say: Bar A, Bar B, Bar C.

Also this text has to be rotated 90 degrees

 

So here is the code to make the bars, I guess I need to use:

$red = imagecolorallocate($im, 255, 0, 0);

imagestring($im, 5, 50, 50, "Bar A", $red);

In some kind of loop

so:

 

$text = array(

imagestring($im, 5, 50, 50, "Bar A", $red);

imagestring($im, 5, 50, 50, "Bar B", $red);

imagestring($im, 5, 50, 50, "Bar C", $red);

);

 

can anyone help?

 

  for($i=0;$i<$columns;$i++)
    {
        $column_height = ($height / 100) * (( $values[$i] / $maxv) *100);

        $x1 = $i*$column_width;
        $y1 = $height-$column_height;
        $x2 = (($i+1)*$column_width)-$padding;
        $y2 = $height;

 

//SQL connect stuff
// This array of values is just here for the example.



    //$values = array("5","6","7");

// Get the total number of columns we are going to plot

    $columns  = count($values);

// Get the height and width of the final image

    $width = 150;
    $height = 200;

// Set the amount of space between each column

    $padding = 15;

// Get the width of 1 column

    $column_width = $width / $columns ;

// Generate the image variables






    $im        = imagecreate($width,$height);
    $gray      = imagecolorallocate ($im,0xcc,0xcc,0xcc);
    $gray_lite = imagecolorallocate ($im,0xee,0xee,0xee);
    $gray_dark = imagecolorallocate ($im,0x7f,0x7f,0x7f);
    $white     = imagecolorallocate ($im,0xff,0xff,0xff);

    $colours = array(
                  imagecolorallocate ($im,0xff,0x00,0xcc),
                  imagecolorallocate ($im,0xcc,0xff,0x00),
                  imagecolorallocate ($im,0x00,0xcc,0xff)
                   );


// Fill in the background of the image

    imagefilledrectangle($im,0,0,$width,$height,$white);

    $maxv = 0;

// Calculate the maximum value we are going to plot

    for($i=0;$i<$columns;$i++)$maxv = max($values[$i],$maxv);

// Now plot each column

    for($i=0;$i<$columns;$i++)
    {
        $column_height = ($height / 100) * (( $values[$i] / $maxv) *100);

        $x1 = $i*$column_width;
        $y1 = $height-$column_height;
        $x2 = (($i+1)*$column_width)-$padding;
        $y2 = $height;

//        imagefilledrectangle($im,$x1,$y1,$x2,$y2,$gray);
   imagefilledrectangle($im,$x1,$y1,$x2,$y2,$colours[$i]);

// This part is just for 3D effect

        imageline($im,$x1,$y1,$x1,$y2,$gray_lite);
        imageline($im,$x1,$y2,$x2,$y2,$gray_lite);
        imageline($im,$x2,$y1,$x2,$y2,$gray_dark);

    }

// Send the PNG header information. Replace for JPEG or GIF or whatever

    header ("Content-type: image/png");
    imagepng($im);
imagedestroy($im);

solved it myself!!!!

 

used needed to add: imagestringup($im, 5, $y1, 190, "Hello World!", $red);

 

// Now plot each column

    for($i=0;$i<$columns;$i++)
    {
        $column_height = ($height / 100) * (( $values[$i] / $maxv) *100);

        $x1 = $i*$column_width;
        $y1 = $height-$column_height;
        $x2 = (($i+1)*$column_width)-$padding;
        $y2 = $height;

//        imagefilledrectangle($im,$x1,$y1,$x2,$y2,$gray);
   imagefilledrectangle($im,$x1,$y1,$x2,$y2,$colours[$i]);
	imagestringup($im, 5, $y1, 190, "Hello World!", $red);

Well nearly sloved,

 

I've narrowed it down to this code snippet, for some reason the array doesnt work, when I have $text = "some text"; is works but plots the same text on each bar.

 

//text array
$text = array("A","B","C");
$red = imagecolorallocate($im, 255, 0, 0);
// Now plot each column

    for($i=0;$i<$columns;$i++)
    {
        $column_height = ($height / 100) * (( $values[$i] / $maxv) *100);

        $x1 = $i*$column_width;
        $y1 = $height-$column_height;
        $x2 = (($i+1)*$column_width)-$padding;
        $y2 = $height;


   imagefilledrectangle($im,$x1,$y1,$x2,$y2,$colours[$i]);
	   imagestringup($im, 5,$x1,$x2,$text,$red);

... should probably be

 

imagestringup($im, 5,$x1,$x2,$text[$i],$red);
