+ | ==RPG Program Usage== | ||
+ | |||
+ | In order to use the GENCHART functionality inside your RPG program, the following is needed: | ||
+ | |||
+ | :a. '''Data structure''': A datastructure has to be passed onto the calling program. This data structure HAS to use the following definitions: | ||
+ | ::- The DataStructure must be limited to 9999 entries. | ||
+ | ::- Field 1 is a description field, 30 chars long. It will be used for the X-Axis | ||
+ | ::- Field 2 is a numeric field, packed 31:2. | ||
+ | |||
+ | *====================================================================* | ||
+ | dcl-ds TestDS qualified dim(9999); | ||
+ | wDescription char(30); | ||
+ | wDataItem packed(31:2); | ||
+ | end-ds; | ||
+ | *====================================================================* | ||
+ | |||
+ | :b. '''GenChart Prototype''': Add the prototype for the external program: | ||
+ | |||
+ | |||
+ | *====================================================================* | ||
+ | dcl-pr GenChart extpgm('GENCHART#R'); | ||
+ | p_InputDS pointer const; | ||
+ | p_Heading char(100) const; | ||
+ | p_Ylabel char(30) const; | ||
+ | p_TotalItems like(TInt) const; | ||
+ | p_MaxValue packed(31:2) const; | ||
+ | p_ChartType char(10) const; | ||
+ | p_YCalc char(10) const; | ||
+ | End-pr; | ||
+ | *====================================================================* | ||
+ | |||
+ | :c. '''Clear the data structure''': You have to clear the data structure before you use it, to ensure it does not contain null values. | ||
+ | |||
+ | *====================================================================* | ||
+ | clear TestDS; | ||
+ | *====================================================================* | ||
+ | |||
+ | :d. '''Build up your SQL String''': | ||
+ | ::- Limit your data to 9999 entries, either in the SQL String or in the fetch statement | ||
+ | ::- Use casting in SQL to ensure the data match the data structure | ||
+ | |||
+ | *====================================================================* | ||
+ | SQLString = | ||
+ | 'SELECT cast( ADATE as char(30)) as "WorkDate", cast(aspsizusd as '+ | ||
+ | 'decimal(31,2)) as "Value" FROM aspinf#p order by aDate'; | ||
+ | *====================================================================* | ||
+ | |||
+ | |||
+ | :e. '''Prepare the SQL cursor now''': | ||
+ | ::- Use SQL diagnostics to determine the number of records returned | ||
+ | |||
+ | *====================================================================* | ||
+ | exec sql Prepare SQLGET1 from :SqlString; | ||
+ | exec sql declare IntCursor1 insensitive cursor for SQLGet1; | ||
+ | exec sql Open IntCursor1; | ||
+ | exec sql get diagnostics :wRecCount = DB2_NUMBER_ROWS; | ||
+ | *====================================================================* | ||
+ | |||
+ | :f. '''Fetch the data''': | ||
+ | |||
+ | *====================================================================* | ||
+ | exec sql fetch IntCursor1 for 9999 rows into :TestDs; | ||
+ | // Cose the Cursor | ||
+ | exec sql close Intcursor1; | ||
+ | *====================================================================* | ||
+ | |||
+ | :g. '''Determine the maximum size for the range''': | ||
+ | |||
+ | *====================================================================* | ||
+ | exec sql select max(aspsiztot) into :wMaxValue from ASPINF#P; | ||
+ | *====================================================================* | ||
+ | |||
+ | :h. '''Generate the chart now''': | ||
+ | |||
+ | *====================================================================* | ||
+ | GenChart(%addr(TestDs):'ASP Information - % Usage':'% Storage': | ||
+ | wRecCount:wMaxValue:'*PCT':'*NONE'); | ||

Green-screen Chart/Graph
Background
It is sometimes useful to display a graph of values on the AS400 green-screen. Although there are commercial products available for the AS400, these are often difficult to use and not available everywhere. This product was designed to allow for a simple text-based line-graph to be displayed on the screen. It will take a data-structure from another program, and build up the screen accordingly.
The program has been written to work correctly on either a wide screen (27x132) or a normal screen(24x80).
Screen Layout
- a. This is the header as passed to the program
- b. This is the Y-label, as passed to the program
- c. The Y-axis values will be build based on the chart type or the chart calc function
- d. If the number of data points exceed the screen width, the program will create additional pages. Page Up/Down will show the rest of the entries. If you want to jump to the 1st page, press F17, or last page press F18.
- e. If you position your cursor on any data item/column, and press F1, the program will display information about the data point
Objects
The following objects will be used by the program:
- a. GENCHART#D - Display File
- b. GENCHART#R – RPG Program
GenChart Program Parameters
The GENCHART#R program requires the following parameters:
- a. Data structure (see point 4):
- - The data structure will be passed from your program, to the GENCHART#R program, by using pointers. When you call the program, the variable has to use %ADDR(DSNAME).
- b. Heading:
- - Char (100).
- - The heading you need for your chart
- c. Y-Axis Label:
- - Char(30)
- - Here you can specify a label for the Y-Axis.
- - Label will be affected by the Chart Type variable
- d. Total Items:
- - Int(10)
- - Specify the number of values to be passed via the DataStructure
- e. Max Value:
- - Packed(31:2)
- - Specify the Maximum value. This is needed to determine the sizing of the bars
- f. Chart Type
- - Char(10)
- - Allows for two types of charts. Can be either
- *PCT: Determine %, betwee max value and actual value
- *NORMAL: Display the values on the screen as they are
- g. Chart Calc:
- - Char(10)
- - If the values are too big, the program can scale them. Allowed values are:
- *NONE – Keep the values as is
- *TB – Scale the values in Terrabytes
- *GB – Scale the values in Gigabytes
- *KB – Scale the values in Megabytes
- *KB – Scale the values in Kilobytes
RPG Program Usage
In order to use the GENCHART functionality inside your RPG program, the following is needed:
- a. Data structure: A datastructure has to be passed onto the calling program. This data structure HAS to use the following definitions:
- - The DataStructure must be limited to 9999 entries.
- - Field 1 is a description field, 30 chars long. It will be used for the X-Axis
- - Field 2 is a numeric field, packed 31:2.
*====================================================================* dcl-ds TestDS qualified dim(9999); wDescription char(30); wDataItem packed(31:2); end-ds; *====================================================================*
- b. GenChart Prototype: Add the prototype for the external program:
*====================================================================* dcl-pr GenChart extpgm('GENCHART#R'); p_InputDS pointer const; p_Heading char(100) const; p_Ylabel char(30) const; p_TotalItems like(TInt) const; p_MaxValue packed(31:2) const; p_ChartType char(10) const; p_YCalc char(10) const; End-pr; *====================================================================*
- c. Clear the data structure: You have to clear the data structure before you use it, to ensure it does not contain null values.
*====================================================================* clear TestDS; *====================================================================*
- d. Build up your SQL String:
- - Limit your data to 9999 entries, either in the SQL String or in the fetch statement
- - Use casting in SQL to ensure the data match the data structure
*====================================================================* SQLString = 'SELECT cast( ADATE as char(30)) as "WorkDate", cast(aspsizusd as '+ 'decimal(31,2)) as "Value" FROM aspinf#p order by aDate'; *====================================================================*
- e. Prepare the SQL cursor now:
- - Use SQL diagnostics to determine the number of records returned
*====================================================================* exec sql Prepare SQLGET1 from :SqlString; exec sql declare IntCursor1 insensitive cursor for SQLGet1; exec sql Open IntCursor1; exec sql get diagnostics :wRecCount = DB2_NUMBER_ROWS; *====================================================================*
- f. Fetch the data:
*====================================================================* exec sql fetch IntCursor1 for 9999 rows into :TestDs; // Cose the Cursor exec sql close Intcursor1; *====================================================================*
- g. Determine the maximum size for the range:
*====================================================================* exec sql select max(aspsiztot) into :wMaxValue from ASPINF#P; *====================================================================*
- h. Generate the chart now:
*====================================================================* GenChart(%addr(TestDs):'ASP Information - % Usage':'% Storage': wRecCount:wMaxValue:'*PCT':'*NONE'); GenChart(%addr(TestDs):'ASP Information':'Size in GB':wRecCount: wMaxValue:'*NORMAL':'*NONE');
