Hello dev and member. Sorry for my bad english.
The following short script that displays the columns in different colors:
<?php
$starttime = microtime(true);
$now = gmdate("D, d M Y H:i:s") . ' GMT';
header ('Date: '.$now);
header ('Expires: '.$now);
header ('Last-Modified: '.$now);
header ('Pragma: no-cache');
header ('Cache-Control: no-store, no-cache, max-age=0, must-revalidate');
include('../libFC/FusionCharts_Gen.php');
$FC = new FusionCharts('ScrollColumn2D',800,400);
$FC->setSWFPath('../libFC/Charts/');
$FC->setInitParam('debugMode',false);
$FC->setParamDelimiter('
);
$tab_alpha = array(100, 90, 80, 70, 60, 50, 40);
$tab_kolory = array();
for ($cr = 0; $cr < 256; $cr += 51) {
for ($cg = 0; $cg < 256; $cg += 51) {
for ($cb = 0; $cb < 256; $cb += 51) {
$tab_kolory[] = strtoupper( sprintf( '%02s%02s%02s', dechex($cr), dechex($cg), dechex($cb) ) );
}
}
}
$tablica = $tab_kolory;
$cyfra = 1000;
$ilosc = count($tablica);
for ($ia = 0; $ia < $ilosc_alpha; $ia++) {
$na = $cyfra + ($ia * $cyfra);
for ($ic = 0; $ic < $ilosc; $ic++) {
$FC->addCategory($na + $ic);
}
}
for ($ia = 0; $ia < $ilosc_alpha; $ia++) {
$na = $cyfra + ($ia * $cyfra);
for ($ic = 0; $ic < $ilosc; $ic++) {
$FC->addChartData(72.34,'label='.($na + $ic).'$toolText=Kolor: '.$tablica[$ic].' Alpha: '.$tab_alpha[$ia].'$color='.$tablica[$ic].'$alpha='.$tab_alpha[$ ia].'
);
}
}
$FC->renderChart(true);
$stoptime = microtime(true);
$total=round($stoptime-$starttime,5);
echo 'Time: '.$total.' sec';
?>
php script execution time: 0.15661 sec - good
Problem: time display in the browser: 11 sec !!!!! and browser it's blocked 5 sec.
The screen stays white and does not show up any words such as "rendering continues". It could use a progress bar.
How to overcome the problem of long waiting times so you see the chart?
Computer CoreDuo 2.66, 4GB RAM, Windows7, IE or FF (browser).
