The following fex produces an error and the resulting .png file has zero bytes. The graph is generated properly if I do a PCHOLD for sending back to the browser (domain was obscured for this post):

SET GRAPHSERVURL=https://*********/ibi_apps/IBIGraphServlet
APP HOLD CONSOL1
APP HOLDDATA
-RUN
GRAPH FILE PNDVTOPV
SUM VT_TOTALVCH
ACROSS VT_OBLTBLSEG
IF VT_OBLTBLSEG EQ 'P0$$$$$$'
ON GRAPH HOLD AS FM4 FORMAT PNG
END

0 NUMBER OF RECORDS IN GRAPH= 95 PLOT POINTS= 95
(FOC3230) HTTP REQUEST RETURNED ERROR: 404 for GRAPHSERVURL
PNG FILE SAVED ...

Try using ON GRAPH SAVE instead of HOLD. you may also have to use the APP FI command to filedef FM4.
