This function allows you to specify the properties of a link between two nodes. You can specify the link color, ticks and text. Parameters are given trough a $Settings array. To learn more about this please read the Format array guide.

Calling this function

linkProperties($FromNode,$ToNode,$Settings);

Where :

FromNode is the ID of the starting node.

ToNode is the ID of the ending node.

You just have to specify one way of the relation : A -> B or B -> A.

Settings array - Tune up your link!

It is possible to customize the color, ticks and text of the link with this array.

Link color can be set with R, G, B.

 $myPicture->setShadow(TRUE,array("X"=>2,"Y"=>2,"R"=>0,"G"=>0,"B"=>0,"Alpha"=>10));

 /* Create the pSpring object */
 $SpringChart = new pSpring();

 /* Define the default free zone size */
 $SpringChart->setNodeDefaults(array("FreeZone"=>100));

 /* Create some nodes & relations */
 $SpringChart->addNode(0,array("Shape"=>NODE_SHAPE_TRIANGLE,"FreeZone"=>60,"Size"=>20,"NodeType"=>NODE_TYPE_CENTRAL));
 $SpringChart->addNode(1,array("Connections"=>"0"));
 $SpringChart->addNode(2,array("Connections"=>"0"));
 $SpringChart->addNode(3,array("Connections"=>"2"));

 /* Define the nodes color */
 $SpringChart->setNodesColor(0,array("R"=>215,"G"=>163,"B"=>121,"BorderR"=>166,"BorderG"=>115,"BorderB"=>74));
 $SpringChart->setNodesColor(array(1,2,3),array("R"=>150,"G"=>215,"B"=>121,"Surrounding"=>-30));

 /* Customize some relations */
 $SpringChart->linkProperties(0,1,array("Name"=>"Synchronous","R"=>255,"G"=>0,"B"=>0));
 $SpringChart->linkProperties(0,2,array("Name"=>"Asynchronous","R"=>255,"G"=>0,"B"=>0,"Ticks"=>2));
 $SpringChart->linkProperties(3,2,array("Name"=>"Mixed","Ticks"=>4));

 /* Render the spring chart */
 $Result = $SpringChart->drawSpring($myPicture);
 print_r($Result);

 /* Render the picture */
 $myPicture->Render("drawspring4.png");
