Docs For Class Image_Graph_Data

Description

Base class for a data-element (e.g. "line" or "bar")

This class provides a basic implementation that is used and extended in all derived data elements. An instance of this class can be used as a "null output" (not actually drawing anything). This is usually *not* needed, however it might be useful in special cases.

drawGD (line 325)

Draws diagram element

access: public

void drawGD (resource &$img, [int $drawWhat = IMAGE_GRAPH_DRAW_FILLANDBORDER])
