computeMissing - Try to compute the missing Matrix points

This function will compute the matrix missing points that are not explicitely set to IGNORED. To compute the missing points this function is using an average algorithm that rely on the random() engine.

Depending on the number of missing points, the result may differ between different rendering.


Calling this function
computeMissing()

This function does not require any parameters.

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(400,400);

 /* Create a solid background */
 $Settings = array("R"=>179, "G"=>217, "B"=>91, "Dash"=>1, "DashR"=>199, "DashG"=>237, "DashB"=>111);
 $myPicture->drawFilledRectangle(0,0,400,400,$Settings);

 /* Do a gradient overlay */
 $Settings = array("StartR"=>194, "StartG"=>231, "StartB"=>44, "EndR"=>43, "EndG"=>107, "EndB"=>58, "Alpha"=>50);
 $myPicture->drawGradientArea(0,0,400,400,DIRECTION_VERTICAL,$Settings);
 $myPicture->drawGradientArea(0,0,400,20,DIRECTION_VERTICAL,array("StartR"=>0,"StartG"=>0,"StartB"=>0,"EndR"=>50,"EndG"=>50,"EndB"=>50,"Alpha"=>100));

 /* Add a border to the picture */
 $myPicture->drawRectangle(0,0,399,399,array("R"=>0,"G"=>0,"B"=>0));
 
 /* Write the picture title */ 
 $myPicture->setFontProperties(array("FontName"=>"../fonts/Silkscreen.ttf","FontSize"=>6));
 $myPicture->drawText(10,13,"pSurface() :: 2D surface charts",array("R"=>255,"G"=>255,"B"=>255));

 /* Define the charting area */
 $myPicture->setGraphArea(20,40,380,380);
 $myPicture->drawFilledRectangle(20,40,380,380,array("R"=>255,"G"=>255,"B"=>255,"Surrounding"=>-200,"Alpha"=>20));

 $myPicture->setShadow(TRUE,array("X"=>1,"Y"=>1));

 /* Create the surface object */
 $mySurface = new pSurface($myPicture);

 /* Set the grid size */
 $mySurface->setGrid(20,20);

 /* Write the axis labels */
 $myPicture->setFontProperties(array("FontName"=>"../fonts/pf_arma_five.ttf","FontSize"=>6));
 $mySurface->writeXLabels();
 $mySurface->writeYLabels();

 /* Add random values */
 for($i=0; $i<=50; $i++) { $mySurface->addPoint(rand(0,20),rand(0,20),rand(0,100)); }

 /* Compute the missing points */
 $mySurface->computeMissing();

 /* Draw the surface chart */
 $mySurface->drawSurface(array("Border"=>TRUE,"Surrounding"=>40));

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