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

GenChart - Overview.png

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');
