Extensions objects are custom objects aimed at visualizing data in a QlikView document. Basically an extension is made of:

• a definition file describing how many dimensions and expressions are used by the object
• a qvpp file defining the graphical appearance of the object properties dialog
• a javascript file with a function called every time the object needs to be refreshed

You should have a look at this tutorial to learn how to create your own extension.
