addPoint - Add points to a surface chart This function allows you to add a point in a surface chart matrix Calling this function
addPoint($X,$Y,$Value,$Force=TRUE)Where : X,Y are the coordinates of the points in the matrix.
Value is the value to write at this point.
Force is an optional parameter. If set to TRUE it will overwrite the current value, if set to FALSE, it will write the average of the current value and the new value. Sample script 
/* pChart library inclusions */
include("../class/pData.class.php");
include("../class/pDraw.class.php");
include("../class/pImage.class.php");
include("../class/pSurface.class.php");
/* Create the pChart object */
$myPicture = new pImage(210,100);
/* Create a solid background */
$Settings = array("R"=>179, "G"=>217, "B"=>91, "Dash"=>1, "DashR"=>199, "DashG"=>237, "DashB"=>111);
$myPicture->drawFilledRectangle(0,0,210,100,$Settings);
/* Do a gradient overlay */
$Settings = array("StartR"=>194, "StartG"=>231, "StartB"=>44, "EndR"=>43, "EndG"=>107, "EndB"=>58, "Alpha"=>50);

/* Add a border to the picture */
$myPicture->drawRectangle(0,0,209,99,array("R"=>0,"G"=>0,"B"=>0));
/* Write the picture title */
