[PHP][Jpgraph] Need Help pour faire des arrondis de courbe

voila mon pti code

Code :

<?php
include("./admin/kevin.inc.php" );
include("./admin/connec.php" );
include "./jpgraph/jpgraph.php";
include "./jpgraph/jpgraph_line.php";
include "./jpgraph/jpgraph_regstat.php";
// Original data points
$graphresult = mysql_query ("-----" ) or die ("la requete a echouee" );
$graphr = @mysql_fetch_array($graphresult);
$chaine = $graphr[TOTO];
$chaine = str_replace(",", ".", $chaine);
$ydata = explode("|", $chaine);
$xdata = array();
for ($i=0;$i<=120;$i++)
{
array_push($xdata,"$i" );
}
// Get the interpolated values by creating
// a new Spline object.
$spline = new Spline($xdata,$ydata);
// For the new data set we want 40 points to
// get a smooth curve.
list($newx,$newy) = $spline->Get(40);
// Create the graph
$g = new Graph(690,433,"auto" );
$g->SetScale('linlin');
$g->SetMargin(50,20,40,40);
$g->SetMarginColor('white');
$g->img->SetAntiAliasing();
// We need a linlin scale since we provide both
// x and y coordinates for the data points.
$g->yaxis->SetLabelmargin(4);
$g->yaxis->SetTitlemargin(35);
$g->xaxis->SetLabelFormat('%1.0f');
$g->yaxis->SetLabelFormat('%1.2f');
$g->yaxis->scale->SetGrace(10,10 );
$g->yaxis->SetTickSide(SIDE_LEFT);
$g->xaxis->SetTickSide(SIDE_DOWN);
// And a line plot to stroke the smooth curve we got
// from the original control points
$lplot = new LinePlot($newy,$newx);
$lplot->SetColor('red');
// Add the plots to the graph and stroke
$g->Add($lplot);
$g->Stroke();
?>

Le resultat

j aurais aimé avoir des arrondis sur les angles de la courbe, si qqn pouvait m aiguiller ?

thx

Quand on trace un graphe correspondant à des données réelles, si ces données sont "anguleuses", le graphe le sera aussi.

Arrondir les angles, ça plonge le problème dans le domaine artistique.
