Graphs in ABAP

Creating graphical charts (bar, pie char, lines graphs) in ABAP is simple.

There are two main methods for creating charts in ABAP
Using the class CL_GFW
Using the function module GFW_PRES_SHOW

There are also other classes and function modules derived from these ones.
Use transaction GRAL to explore all possibilities provided by this class and this FM.
The following are two short examples of the huge potential of function module GFW_PRES_SHOW :

The Code:
* Contain the constants for the graph type

TYPE-POOLS: GFW.
DATA: VALUES TYPE TABLE OF GPRVAL WITH HEADER LINE,
COLUMN_TEXTS TYPE TABLE OF GPRTXT WITH HEADER LINE.

REFRESH VALUES.
REFRESH COLUMN_TEXTS.

VALUES-ROWTXT = 'Salary'.
VALUES-VAL1 = 50000.
VALUES-VAL2 = 51000.
APPEND VALUES.
VALUES-ROWTXT = 'Life cost'.
VALUES-VAL1 = 49000.
VALUES-VAL2 = 51200.
APPEND VALUES.
COLUMN_TEXTS-COLTXT = '2003'.

APPEND COLUMN_TEXTS.
COLUMN_TEXTS-COLTXT = '2004'.

APPEND COLUMN_TEXTS.

* Call a chart into a standard container, this function could be used for many different graphic
* types depending on the presentation_type field :
* gfw_prestype_lines
* gfw_prestype_area
* gfw_prestype_horizontal_bars
* gfw_prestype_pie_chart
* gfw_prestype_vertical_bars
* gfw_prestype_time_axis

CALL FUNCTION 'GFW_PRES_SHOW'
EXPORTING
CONTAINER = 'CONTAINER' "A screen with an empty container must be defined PRESENTATION_TYPE = GFW_PRESTYPE_LINES
TABLES
VALUES = VALUES
COLUMN_TEXTS = COLUMN_TEXTS
EXCEPTIONS
ERROR_OCCURRED = 1
OTHERS = 2.
