I have a series of graphs on a dashboard. Sometimes no data is present. I wanted to print a little message: No Data Present when th egraph is empty. I took the following approach but it does not seem the IF statement is evaluated correctly. It prints the message no matter what... Anyone see something wrong with my syntax?


.
.
.

-IF &LINES.EVAL EQ 0 THEN GOTO GRAPHIT;
DEFINE FILE TBLMSTR_CALENDARPERIOD
MESSAGE/A50='There is no Data to Graph!';
END
TABLE FILE TBLMSTR_CALENDARPERIOD
BY LOWEST 1 TBLMSTR_CALENDARPERIOD.TBLMSTR_CALENDARPERIOD.FISCALYEAR NOPRINT
BY MESSAGE AS 'New Inpatient Visits - MESSAGE!'
HEADING
" "
" "
" "
" "
ON TABLE SET PAGE-NUM NOLEAD
ON TABLE NOTOTAL
ON TABLE PCHOLD FORMAT HTML
ON TABLE SET HTMLCSS ON
ON TABLE SET STYLE *
INCLUDE = endeflt,
$
TYPE=DATA,
COLUMN=N2,
SIZE=18,
COLOR='BLUE',
$
TYPE=TITLE,
COLUMN=N2,
SIZE=18,
COLOR='PURPLE',
BACKCOLOR=RGB(51 204 204),

You need to stop the program or branch somewhere else before the GRAPH_IT label

Also you do not need the .EVAL on &LINES.

You have a GOTO GRAPHIT and a label GRAPH_IT, is this a typo ?

Agree on the branching but for now it hits the IF statement and should jump to the GRAPHIT section if there is no data, however it seems to ignore the IF statement and do both no matter what.

I originally had:
SET EMPTYREPORT = ON

that works but leaves a rather odd looking empty space!

Yes typo...

ok, if I have data....it prints 'There is no Data to Graph' then prints the graph. Should it not bypass the code causing the message????

Here is the latest code:

-IF &LINES.EVAL NE 0 THEN GOTO GRAPHIT;
DEFINE FILE TBLMSTR_CALENDARPERIOD
MESSAGE/A50='There is no Data to Graph!';
END
TABLE FILE TBLMSTR_CALENDARPERIOD
BY LOWEST 1 TBLMSTR_CALENDARPERIOD.TBLMSTR_CALENDARPERIOD.FISCALYEAR NOPRINT
BY MESSAGE AS 'New Inpatient Visits - MESSAGE!'

Have you run the code with -SET &ECHO=ALL; to see what is happening with values ?

What is the previous step that produces the &LINES ?

Try putting a -GOTO SKIPGRPH after the no data report.

-IF &LINES.EVAL NE 0 THEN GOTO GRAPHIT;
DEFINE FILE TBLMSTR_CALENDARPERIOD
MESSAGE/A50='There is no Data to Graph!';
END
TABLE FILE TBLMSTR_CALENDARPERIOD
BY LOWEST 1 TBLMSTR_CALENDARPERIOD.TBLMSTR_CALENDARPERIOD.FISCALYEAR NOPRINT 
BY MESSAGE AS 'New Inpatient Visits - MESSAGE!'

-GOTO SKIPGRPH

-GRAPHIT

The issues seem to be:

1)When data is present, it prints both the no data found message and graph

2) when no data is present it prints the message..I can not tell whats happening with the grapgh...there is no data...I see no nothing.

I tried the echo thing, then viewed the source. I ran the report for an area where I know there is data...it printed the message and graph.....the Echo ended with this...

0 NUMBER OF RECORDS IN TABLE= 2134 LINES= 2134
0 NUMBER OF RECORDS IN TABLE= 6 LINES= 6
0 NUMBER OF RECORDS IN TABLE= 24 LINES= 12
0 NUMBER OF RECORDS IN TABLE= 18 LINES= 18
0 HOLDING HTML FILE ON PC DISK ...
1
0 NUMBER OF RECORDS IN TABLE= 1 LINES= 1
0 NUMBER OF RECORDS IN GRAPH= 18 PLOT POINTS= 12

I noticed this too w/&ECHO=ALL:


-IF 0 NE 0 THEN GOTO GRAPHIT
DEFINE FILE TBLMSTR_CALENDARPERIOD
MESSAGE/A50='There is no Data to Graph!';
END
TABLE FILE TBLMSTR_CALENDARPERIOD
BY LOWEST 1 TBLMSTR_CALENDARPERIOD.TBLMSTR_CALENDARPERIOD.FISCALYEAR NOPRINT
BY MESSAGE AS 'New Inpatient Visits - MESSAGE!'

hmmm...can someone explain the difference between &LINES and &LINES.EVAL...I seem to be having some luck when I change top IF statement to:

-IF &LINES NE 0 THEN GOTO GRAPHIT

We add this at the end of each fex

-INCLUDE IBFS:/WFC/Repository/Landscape/no_records.fex



The code for no_records:

-IF &LINES EQ 0 THEN GOTO TABLE1 ELSE GOTO OTHERS;

-TABLE1
TABLE FILE CAR
PRINT COUNTRY NOPRINT
WHERE RECORDLIMIT LE 1;
HEADING
"There is No Data that Matches Your Selection"
END

-OTHERS
