Dear ladies and gentlemen
How to realize the y axis in reverse chronological order shown?
Thank you very much!


Code:
<?php
/* CAT:Line chart */

/* pChart library inclusions */
include("pchart/class/pData.class.php");
include("pchart/class/pDraw.class.php");
include("pchart/class/pImage.class.php");

/* Create and populate the pData object */
$MyData = new pData();
$google=array(3,12,15,8,5,100);
$yahoo=array(1,7,5,18,19,1);


$MyData->addPoints($google,"Google");
//$MyData->reverseSerie("Google");
$MyData->addPoints($yahoo,"Yahoo");
//$MyData->setSerieTicks("Google",1);
$MyData->setSerieWeight("Google",1);
//$MyData->setSerieTicks("Yahoo",1);
$MyData->setSerieWeight("Yahoo",1);
$MyData->setAxisName(0,"#Rank");

$MyData->addPoints(array("Jan","Feb","Mar","Apr","May","Jun"),"Labels");

$MyData->setSerieDescription("Labels","Months");
$MyData->setAbscissa("Labels");





/* Create the pChart object */
$myPicture = new pImage(551,230,$MyData);

/* Turn of Antialiasing */
$myPicture->Antialias = FALSE;

/* Add a border to the picture */
$myPicture->drawRectangle(0,0,550,229,array("R"=>0,"G"=>0,"B"=>0));

/* Write the chart title */
//$myPicture->setFontProperties(array("FontName"=>"pchart/fonts/verdana.ttf","FontSize"=>8));
//$myPicture->drawText(60,35,"keyword",array("FontSize"=>14,"Align"=>TEXT_ALIGN_BOTTOMMIDDLE));

/* Set the default font */
$myPicture->setFontProperties(array("FontName"=>"pchart/fonts/verdana.ttf","FontSize"=>8));

/* Define the chart area */
$myPicture->setGraphArea(60,40,530,200);

/* Draw the scale */
$AxisBoundaries = array(0=>array("Min"=>1,"Max"=>100));
$scaleSettings = array("Mode"=>SCALE_MODE_MANUAL,"ManualScale"=>$AxisBoundaries,"XMargin"=>10,"YMargin"=>10,"Floating"=>TRUE,"GridR"=>200,"GridG"=>200,"GridB"=>200,"DrawSubTicks"=>TRUE,"CycleBackground"=>TRUE);
//$scaleSettings = array("XMargin"=>10,"YMargin"=>10,"Floating"=>TRUE,"GridR"=>200,"GridG"=>200,"GridB"=>200,"DrawSubTicks"=>TRUE,"CycleBackground"=>TRUE);
$myPicture->drawScale($scaleSettings);

/* Turn on Antialiasing */
$myPicture->Antialias = TRUE;

/* Draw the line chart */
$myPicture->drawLineChart(array("DisplayValues"=>TRUE,"DisplayColor"=>DISPLAY_AUTO));

/* Write the chart legend */
$myPicture->drawLegend(425,20,array("Style"=>LEGEND_NOBORDER,"Mode"=>LEGEND_HORIZONTAL));

$myPicture->Render("test.png");

/* Render the picture (choose the best way) */
$myPicture->autoOutput("pchart/examples/pictures/example.drawLineChart.simple.png");
