PHP - Help Ammending A Graph Script

Hi everyone,

Newish to PHP and I'm sure this is a simple thing but I was hoping someone could help me out.

I have a php file that draws a graph for me (it takes in the coordinates from a text file). What I want to do is insert a red line at the top of the graph (not from start to finish, but starting at a certain point in the graph and finishing at another point).

This php code achieves the line I would like to insert into the graph:

<?php
$canvas = imagecreatetruecolor(1000, 10);

// Allocate colors
$red = imagecolorallocate($canvas, 255, 0, 0);

ImageFilledRectangle($canvas, 0, 0, 1000, 10, $red);


// Output and free from memory
header('Content-Type: image/jpeg');

imagejpeg($canvas);
imagedestroy($canvas);
?>


I need to insert this into this php script:

<?php
$width = 1000; //width and height of the resulting image
$height = 230;

$drawLastLine = false; //draw 9th line or not
$testMode = false; //render only 10 images



//returns directory with cached images by name of text file
function getCacheDirectory($fname)
{
    $mod = filemtime($fname);
    $dirname = "cache/" . $fname . "." . $mod . "/";
    return $dirname;
}

//checks if specified txt file is cached
function isCached($fname)
{
    $dirname = getCacheDirectory($fname);
    return file_exists($dirname);
}

//calculated y-coordinates of base-lines for all 9 lines, returns an array

I'm just lost as to how I achive this line in the longer php script. I've tried creating my own function, and then calling it further down but this just breaks it. Any help is appreciated!!

I'm trying to get a bar graph from total number of hit on a month to month basis.

Everything works out find, except the bar graph is only showing 1 month, not everything that's being pulled out of the db.

Can anybody look and see what I'm doing wrong?

Code: [Select]
$userid = '44';

$y_month = date("Y-m-d h:i:s", strtotime("-1 Year"));

//Grabs Unique Visitors to App Page

Anyone can help me with plotting of multiple line graph in php.

I have researched on multiple line graph online and  I would like to plot the graph by taking data from my database but the example below is inserting the graph data manually.
Anyone can teach me how to use a for loop inside an array?

Code: [Select]
<?php
//Include the code
require_once 'phplot.php';

//Define the object
$plot = new PHPlot(800,600);

//Set titles
$plot->SetTitle("A 3-Line Plot\nMade with PHPlot");
$plot->SetXTitle('X Data');
$plot->SetYTitle('Y Data');

//Define some data
$example_data = array(
     array('a',3,4,2),
     array('b',5,3,1),  
     array('c',7,2,6),
     array('d',8,1,4),
     array('e',2,4,6),
     array('f',6,4,5),
     array('g',7,2,3)
);
$plot->SetDataValues($example_data);

//Turn off X axis ticks and labels because they get in the way:
$plot->SetXTickLabelPos('none');
$plot->SetXTickPos('none');

//Draw it
$plot->DrawGraph();
?>

Following Sams PHP 24hrs... Rewrote Example and it isn't working... I am not getting any syntax error just an error saying it cannot display the graph because there are errors in the image.  I have went through it line for line looking for mispellings you name it making sure it was exactly as they wrote so I could follow along... but now its is not working and I believe its me.. not the book... can anyone help me out?

I need a simple line graph for my PHP site showing page views against date (monthly). Have tried to find plugins but can't find an appropriate one. Can someone please help with a script or direct me to a plugin.

Attached is the kind of graph I'd like to have.

For the life of me, I cannot find a way to delete, cancel or remove facebook events I created & updated using the FB PHP SDK & the Graph API.

I've tried every single permutation found on facebook's documentation & stack overflow...

Here are some of the clues I have found on my quest..

https://developers.facebook.com/docs/reference/api/#deleting https://developers.facebook.com/docs/reference/api/event/ https://developers.facebook.com/docs/reference/rest/events.cancel/

http://stackoverflow.com/questions/2858748/facebook-api-delete-status
http://stackoverflow.com/questions/3832405/facebook-graph-api-delete-like

Here is what I have tried so far.
function delete_fb_event($event_data, $data)
{
    //load the user for offline access and userid
    $user = $this->load_user($data['aid']);

    if(!empty($user[0]['fb_offline_access']))
    {
        //instantiate Facebook API
        require 'facebook.php';
        $facebook = new Facebook(array(
          'appId'  => 'BLAHBLAHBLAH',
          'secret' => 'BLAHBLAHBLAHBLAHBLAHBLAH',
          'cookie' => true,
        ));

        $fb_event = array(
            "access_token" => $user[0]['fb_offline_access'],
        );

        $result = $facebook->api('/'.$event_data['fb_event_id'], 'DELETE', $fb_event); //Uncaught GraphMethodException: Unsupported delete request
        //$result = $facebook->api('/'.$user[0]['fb_id']."_".$event_data['fb_event_id'], 'POST', array('access_token' => $user[0]['fb_offline_access'], 'method' => 'delete')); Uncaught OAuthException: (#803) Some of the aliases you requested do not exist

        return $result;         
    }
    else
    {
        echo "error3"; //no FB offline access
    }       
}   

I have the following code:

Code: [Select]
private function buildJSResponse(){
$data = "";
$i = 0;
$arr = array();
while($this->db->row()){
$arr[] = (int)$this->db->field("average");
}
$this->max = max($arr);
$this->min = min($arr);
$this->mid = round(($this->max + $this->min) / 2);
foreach($arr as $val){
$nTime = ($val / $this->max) * 100;
$data .= "data[$i] = ".$nTime.";";
$i++;
}
return $data;
}
It takes an array, finds the max/min and number halfway between the min/max.
The next part I am not sure what to do.

I am making a line graph using the canvas, so I am building a javascript array, which will contain the point on the chart. The problem I am having, is location.
Lets say $max = 110, and $min = 95.
the y position on the graph should be 0 for $max, and 100 for $min, then all the other points need to fall into their place as well.

$nTime is supposed to do that, but it doesn't any suggestions?

The attachment is the result I am getting from my above code.
As you can see the lowest number is 49, so the value with 49 should touch the bottom, which it doesn't.

Hello people, currently i ran into some problem.

Currently, i have a database called responses which have the fields of ID, Student_id, question_id, Answer.

I had stored my results into the database which appeared to be           1       1                  1             Agree
                                                                                                                 2       1                  2            Disagree
                                                                                                                 3        3                 4             Unsatisfied.

So any recommendation on how should i do about in generating the result into a graph whereby the graph will show how many students choose "AGree" on that particular question THANKS

Hello,

I stored a fsockopen function in a separate "called.php" file, in order to run it as another thread when it needs.
The called script should return results to the "master.php" script.
I'm able to run the script to get the socket working, and I'm able to get results from the called script. I tried for hours but I can't do the twice both 

My master.php script (with socket working):

Code: [Select]
<?php
$command = "(/mnt/opt/www/called.php $_SERVER[REMOTE_ADDR] &) > /dev/null";
$result = exec($command);
echo ("result = $result\r\n");
?>

and my called.php script
Code: [Select]
#!/mnt/opt/usr/bin/php-cli -q
<?php
$device = $_SERVER['argv'][1];
$port = "8080";
$fp = fsockopen($device, $port, $errno, $errstr, 5);
fwrite($fp, "test");
fclose($fp);
echo ("normal end of the called.php script");
?>

In the master script, if I use
Code: [Select]
$command = "(/mnt/opt/www/called.php $_SERVER[REMOTE_ADDR] &) > /dev/null";
the socket works, but I have nothing in $result
(note also that I don't anderstand why the ( ... &) are needed!?)

and if I use
Code: [Select]
$command = "/mnt/opt/www/called.php $_SERVER[REMOTE_ADDR]";
I have the correct text "normal end of the called.php script" in $result but the socket connection is not performed (no errors in php logs)

Could you help me to find a way to let's work the two features correctly together?
Thank you.
