Here's an example. This generates a graph showing order quantities for every day in year 2001 that had data. Along the x-axis, we only show the month-end date. This is done using the DEFINE virtual column ORDER_DATE_EOM_TXT and a series of BY statements. In this way, we have the each day's quantity plotted on the graph, but only show the month-end date in the labels.

I would also like to control when the data value is displayed above the point in the graph. When I set setDataTextDisplay to true, all points have the data value displayed - I only want to see them for the mont-end dates.

Is there a way to achieve this?

Thanks.

TABLE FILE CENTORD
SUM
COMPUTE QUANTITY_MM/D6 = QUANTITY / 1000;
BY ORDER_DATE
WHERE ORDER_DATE FROM '2001-01-01' TO '2001-12-31'
ON TABLE HOLD AS HCENTORD
END
-RUN

DEFINE FILE HCENTORD
ORDER_DATE_EOM/YYMD    = DATEMOV(ORDER_DATE, 'EOM');
CTR/I4                 = IF ORDER_DATE_EOM NE LAST ORDER_DATE_EOM THEN 1 ELSE CTR + 1;
ORDER_DATE_EOM_TXT/A10 = IF (ORDER_DATE EQ ORDER_DATE_EOM) THEN DATETRAN(ORDER_DATE, '(MD)', '(td)', 'EN', 10, 'A10') ELSE ' ';
END
-RUN

Hi Francis,

According to threedgraphics perspective for Java documentation it is either on or off for the entire graph.

I was afraid of that. Thanks for the confirmation.

I haven't looked at your example extensively, but perhaps you can COMPUTE MISSING values for those dates that are not a month-end date?
You can hide missing values in graphs, after all. If you were to combine that with a series that draws an invisible line through the existing values, I think you could achieve what you want...
