Require pChart 2.0.11

The pStock extension allows you to create stock charts. As one data point is characterized by 4 values, you‘ll have to use your datasets in a different way than when you‘re drawing standard charts. Each data points is defined by the following states :


All this values have to be listed in dedicated datasets. You can also use an extra dataset to put your X axis labels.


Let‘s assume that we got the data represented in the table bellow :



This will lead to the following declaration with the pData object structure :

 /* Create the pData object */
 $MyData = new pData();  

 /* Populate the data series */
 $MyData->addPoints(array(34,55,15,62,38,42),"Open");
 $MyData->addPoints(array(42,25,40,38,49,36),"Close");
 $MyData->addPoints(array(27,14,12,25,32,32),"Min");
 $MyData->addPoints(array(45,59,47,65,64,48),"Max");

 /* Populate the X lables serie */
 $MyData->addPoints(array("8h","10h","12h","14h","16h","18h"),"Time");
 $MyData->setAbscissa("Time");

That can be charted this way :
