jpgraph setup problem

wokoci · July 21st, 2003, 02:14 PM

I got the book on php graphics but it has been a real nightmare tring out the codes in chapter 7 due to problems installing jpgraph.

I am using windows 2000,
I have been trying for days to get the install write without success.
I have php 4.2.2 installed plus GD, which i have tested based on the test from the manual.

I have downloaded the jpgraph files and have same saved in a folder under the php folder.

I have never been able to get any of the example graphs to work, and get the following errors:

Warning: Failed opening '../jpgraph.php' for inclusion (include_path='.;c:\php4\pear') in C:\FoxServ\www\test.php on line 2

Warning: Failed opening '../jpgraph_line.php' for inclusion (include_path='.;c:\php4\pear') in C:\FoxServ\www\test.php on line 3

Fatal error: Cannot instantiate non-existent class: graph in C:\FoxServ\www\test.php on line 9

I have pointed my browser to the location of the example suites after saving the scr folder from the
jpgraph files in my web roots folder.

The graphs still will not display, but i can see the codes when i click on the position where the graphs should be.

Please help, i dont know where i am going wronge.

Well, it looks simple enough -- you're not including the jpgraph files properly.

You're trying to include '../jpgraph.php' from c:\FoxServe\www\test.php. So unless jpgraph.php is in c:\FoxServe\, or in c:\php4, it's not going to work.

Specify the correct path to jpgraph.php, or add the jpgraph src dir to your include path and just include "jpgraph.php" (no "../").

Take care,

Dear Nik,

I have made the changes as you recommended to my php.ini,
by adding the path to the include directory.

I now get the following error:

Parse error: parse error, unexpected '}' in c:\php4\pear\jpgraph.php on line 444

Fatal error: Class lineplot: Cannot inherit from undefined class plot in c:\php4\pear\jpgraph_line.php on line 24

the examples still do not display proparly also.

Is it neccessary to enable the cashe and font facility provided by
jpgraph?

Please help!!

This means you've left out a curly brace or have one too many. You need to proofread your code to get rid of this error. Albeit at or near line 444 - though curly brace parse errors can sometimes be anywhere in the script.

Correcting that error could by all rights correct your other error. Feel free to post some code, it helps us better understand your questions.

If it were me I would have a (further) look at the documentation. If the script requires a particular font that could cause it to display improperly. Again, it helps to see the code associated with your questions.

Rich -- this doesn't necessarily mean that he's left any curly braces out. jpgraph is a freely available PHP software library; if there are any parse errors in the code, they're not likely to be found in the public stable release.

Still, it's worth looking at WHAT is near line 444 in that file; perhaps something's not being defined or included properly...

thanks for all the responces so far. I have modified my include_path to c:\foxsev\www. and i now get the following error:

Warning: Failed opening 'jpgraph.php' for inclusion (include_path='.c:\foxserv') in C:\FoxServ\www\test.php on line 2

Warning: Failed opening 'jpgraph_line.php' for inclusion (include_path='.c:\foxserv') in C:\FoxServ\www\test.php on line 3

Fatal error: Cannot instantiate non-existent class: graph in C:\FoxServ\www\test.php on line 9

the following a the sample i am trying to view:

<?php
include ( "jpgraph.php");
include ("jpgraph_line.php");

// Some data
$ydata = array(11,3, 8,12,5 ,1,9, 13,5,7 );

// Create the graph. These two calls are always required
$graph = new Graph(350, 250,"auto");
$graph->SetScale( "textlin");

// Create the linear plot
$lineplot =new LinePlot($ydata);
$lineplot ->SetColor("blue");

// Add the plot to the graph
$graph->Add( $lineplot);

// Display the graph
$graph->Stroke();
?>

PLease help

Your include path looks screwy... ".c:\foxserv".

Again, where did you install/unzip the jpgraph library? That directory should be in your include path. Be sure to properly separate the directories in your include path.

Also, make sure that error_reporting = E_ALL.

Take care,

Okay, I just downloaded the jpgraph library, unzipped it to a directory, added the src directory to my include_path, and voila -- it worked.

Here's the sample script I used to test my installation. Note that this script is taken directly from the jpgraph documentation, with one minor set of modifications. "..\" was removed from the include lines; for example:
include("..\jpgraph.php");
was changed to
include("jpgraph.php");

Code:

<?php
// $Id: listfontsex1.php,v 1.3 2002/10/25 22:44:15 aditus Exp $
include "jpgraph.php";
include "jpgraph_canvas.php";
include "jpgraph_canvtools.php";


$g = new CanvasGraph(550,450,'auto');
$scale = new CanvasScale($g);
$scale->Set(0,27,0,53);
$g->SetMargin(5,6,5,6);
$g->SetColor('white');
$g->SetMarginColor("teal");
$g->InitFrame();


$t = new CanvasRectangleText();
$t->SetFillColor('lightgreen');
$t->SetFontColor('navy');
$t->SetFont(FF_ARIAL,FS_NORMAL,16);
$t->Set("\n\n\n\n\n\n\n\n\n\n\nTTF Fonts",0.5,19,26,32);
$t->Stroke($g->img,$scale);


$t = new CanvasRectangleText();

$t->SetFillColor('');
$t->SetFontColor('black');
$t->SetColor('');
$t->SetShadow('');
$t->SetFont(FF_ARIAL,FS_BOLD,18);
$t->Set('Family',1,1,8);
$t->Stroke($g->img,$scale);

$t->Set('Italic style',9,1,8);
$t->Stroke($g->img,$scale);

$t->Set('Bold style',17.5,1,8);
$t->Stroke($g->img,$scale);


$t->SetFillColor('yellow');
$t->SetFontColor('black');
$t->SetColor('black');
$t->SetShadow('gray');

$r=6;$c=1;$w=7.5;$h=3.5;

$fonts=array(
    array("Font 0",FF_FONT0,FS_NORMAL),
    array("",FF_FONT0,FS_ITALIC),
    array("",FF_FONT0,FS_BOLD),

    array("Font 1",FF_FONT1,FS_NORMAL),
    array("",FF_FONT1,FS_ITALIC),
    array("Font 1 bold",FF_FONT1,FS_BOLD),

    array("Font 2",FF_FONT2,FS_NORMAL),

    array("Trebuche bold",FF_TREBUCHE,FS_BOLD),

    array("Georgia",FF_GEORGIA,FS_NORMAL),
    array("Georgia italic",FF_GEORGIA,FS_ITALIC),

    array("Times normal",FF_TIMES,FS_NORMAL),
    array("Times italic",FF_TIMES,FS_ITALIC),
    array("Times bold italic",FF_TIMES,FS_BOLDITALIC),
    );


$n=count($fonts);

for( $i=0; $i < $n; ++$i ) {

    if( $i==9 ) $r += 3;

    if( $fonts[$i][0] ) {
    $t->SetTxt($fonts[$i][0]);
    $t->SetPos($c,$r,$w,$h);
    $t->SetFont($fonts[$i][1],$fonts[$i][2],13);
    $t->Stroke($g->img,$scale);
    }

    $c += $w+1;
    if( $c > 30-$w-2 ) {
    $c = 1;
    $r += 4;
    }

}

$g->Stroke();
?>

For reference, my include path is:
".;c:\WebHome\lib\jpgraph-1.12.2\src"

Hi Nik,
I was able to get jpgraph working on my system based on the
explanation you gave below.

Thank you very much for all your help.
