Librerie gd...cosa c'è che non va!?

...ciao mitici!

Sapete svelarmi un mistero?

Perchè questi capolavori (pchart.sourceforge.net) non mi funzionano, e queste ciofekine(makko.com.mx/gdgraph/) invece sì?

Proprio non mi capacito...nella mia ignoranza suppongo che tutte e due le classi sfruttino le librerie gd....ma perchè il primo non funziona?

Tanto di cappello a makko, per carità, però pChart fa sbavare solo a vedere le anteprime!

Aggiungo che ho Apache 2.2.8 e PHP 5.2.6....

Ciao ciccio6630,

la tua domanda e' un po' generica. Prova a darci piu' informazioni del tipo: quale errore ti da pchart?

Facci sapere

ciccio6630

uno dei misteri è proprio questo: niente errori!

Il php restituisce un output pulito come solo mastro lindo sa fare!

Ti incollo un esempio a caso che in teoria dovrebbe funzionare:

Example1.php
[php]
<?php

include("pChart/pData.class");
include("pChart/pChart.class");

$DataSet = new pData;
$DataSet->ImportFromCSV("Sample/bulkdata.csv",",",array(1,2,3),FALSE,0);
$DataSet->AddAllSeries();
$DataSet->SetAbsciseLabelSerie();
$DataSet->SetSerieName("January","Serie1");
$DataSet->SetSerieName("February","Serie2");
$DataSet->SetSerieName("March","Serie3");

$Test = new pChart(700,230);
$Test->setFontProperties("Fonts/tahoma.ttf",8);
$Test->setGraphArea(60,30,680,200);
$Test->drawFilledRoundedRectangle(7,7,693,223,5,240,240,240);
$Test->drawRoundedRectangle(5,5,695,225,5,230,230,230);
$Test->drawGraphArea(255,255,255,TRUE);
$Test->drawScale($DataSet->GetData(),$DataSet->GetDataDescription(),5,150,150,150,TRUE,0,2);
$Test->drawGrid(4,TRUE,230,230,230,50);

$Test->setFontProperties("Fonts/tahoma.ttf",6);
$Test->drawTreshold(0,143,55,72,TRUE,TRUE);

$Test->drawLineGraph($DataSet->GetData(),$DataSet->GetDataDescription());
$Test->drawPlotGraph($DataSet->GetData(),$DataSet->GetDataDescription(),3,2,255,255,255);

$Test->setFontProperties("Fonts/tahoma.ttf",8);
$Test->drawLegend(65,35,$DataSet->GetDataDescription(),255,255,255);
$Test->setFontProperties("Fonts/tahoma.ttf",10);
$Test->drawTitle(60,22,"example 1",50,50,50,585);
$Test->Render("example1.png");
?>

...mi viene impossibile incollarti il sorgente delle classi perchè mi dice che non sono un utente premium.... :bho:

...che stupido...era perchè c'erano dei links...

questo è pData.class

...l'altro è troppo grosso e non me lo fa postare....

Non e' che questo script ti genera solo l'immagine "example1.png" sul server e non mostra nulla a video?

Prova a controllare.
