[MANDATORY]:default initialization. This will fill the graph data structure with general default parameters that can be used directly. This would typically be the first API to be called in the process of creating graphs.e.g.
GraphInfo_t gr;
grLibInitializeGraphStruct(&gr);
NOTE:It is advisable to save the current pattern/color etc. attributes before drawing a graph. Due to OS version API differences, the API's do not save current attributes and restore on exit.
