Documentation

[OPTIONAL]:This function draws the legends below the graph. Using values in the graph data structure, it automatically calculates space available for printing legends and prints the information in as many columns as specified in this function call. Note that the legend information is based on the group id assigned to the data.

Parameters:

br - pointer to the graph data structure
numLegendColumns - specifies the number of columns in which the legends are printed. The caller must decide what would be best for the print by calculating the length of the strings. For legends with 4 to 5 characters a 3 column fits best. It is recommended that legend strings be limited to about 4 or 5 characters.

Returns:

none
