Post subject:  PieChart2D positions of labels uncorrect
Hi all,

I have encoutered a problem with position of labels only
when data have some specific values !

See:
http://webservices.ipsl.fr/migration/bug_pie_labels.php

The code is simple as it should be.
Now change array(5,1,1) to array(5,1,2)
and the labels are set correctly.

Note that with pie3D, the labels are well positionned.

Any help and corrections to class/pPie.class.php
are welcome

Regards
Patrick

$w=200;

$myData->addPoints(array(5,1,1));

$myData->addPoints(array("ok","failed","todo"),"Labels");

$myPicture = new pImage($w,$w,$myData,TRUE);
$myPicture->setFontProperties(array("R"=>0,"G"=>0,"B"=>0,

$Settings = array("R"=>100, "G"=>100, "B"=>100, "Alpha"=>0);
$myPicture->drawFilledRectangle(0,0,100,100,$Settings);

/* Create the pPie object */
$PieChart = new pPie($myPicture,$myData);

$PieChart->setSliceColor(0,array("R"=>187,"G"=>224,"B"=>45));
$PieChart->setSliceColor(1,array("R"=>252,"G"=>71,"B"=>43));
$PieChart->setSliceColor(2,array("R"=>46,"G"=>186,"B"=>224));

$PieChart->draw2DPie($w/2,$w/2,array("WriteValues"=>PIE_VALUE_NATURAL,"ValuePosition"=>PIE_VALUE_INSIDE,
"ValueR"=>0,"ValueG"=>0,"ValueB"=>0,"DrawLabels"=>FALSE,
"Radius"=>$w*0.4,"Border"=>TRUE));

$myPicture->Stroke();

I fixed this problem as follows

Replace on 266 str.
Code:
$EndAngle = ($Value*$ScaleFactor) + $Offset; if ( $EndAngle > 360 ) { $EndAngle = 0; }
by
Code:
$EndAngle = ($Value*$ScaleFactor) + $Offset; if ( $EndAngle > 360 ) { $EndAngle = 360; }

OR on 267 str.
Code:
$Angle    = ($EndAngle - $Offset)/2 + $Offset;
by
Code:
$Angle    = (((360+$EndAngle - $Offset)%360)/2 + $Offset;

Unfortunately, the paint because of what happened so I can not, so how bad know English
