include("pChart/pChart.class");

include("pChart/pCache.class");

// Dataset definition

$DataSet = new pData;

$DataSet->AddPoint(array(1,4,3,2,3,3,2,1,0,7,4,3,2,3,3,5,1,0,7),"Serie1");

$DataSet->AddPoint(array(1,4,2,6,2,3,0,1,5,1,2,4,5,2,1,0,6,4,2),"Serie2");

$DataSet->AddAllSeries();

$DataSet->SetAbsciseLabelSerie();

$DataSet->SetSerieName("January","Serie1");

$DataSet->SetSerieName("February","Serie2");

// Cache definition

$Cache = new pCache();

$Cache->GetFromCache("Graph1",$DataSet->GetData());

// Initialise the graph

$Test = new pChart(700,230);
