WORD StructSize

Specifies the size of the PEGraphDataInfo structure. You must initialize this member to be the size of the structure.
For example: info.StructSize = PE_SIZEOF_GRAPH_DATA_INFO.

short rowGroupN

Specifies which group number in the report is used to create the values in the rows of the graph. Use PE_GRAPH_DATA_NULL_SELECTION if you don't want to specify a value.

short colGroupN

Specifies which group number in the report is used to create the values in the columns of the graph. Use PE_GRAPH_DATA_NULL_SELECTION if you don't want to specify a value.

short summarizedFieldN

Specifies which summary field in the report is used to set the values of the risers in the graph. Summary fields are numbered in order of their creation. Use PE_GRAPH_DATA_NULL_SELECTION if you don't want to specify a value.

short graphDirection

For normal group/total report, the direction, is always PE_GRAPH_COLS_ONLY. For cross-tab reports, use any of the following constant values:

• PE_GRAPH_ROWS_ONLY Use only row values in graph.
• PE_GRAPH_COLS_ONLY Use only column values in graph.
• PE_GRAPH_MIXED_ROW_COL Graph by row values, then by column values.
• PE_GRAPH_MIXED_COL_ROW Graph by column values, then by row values.
• PE_GRAPH_UNKNOWN_DIRECTION The direction of the graph is unknown.
