Hi,
This is the graph that I have now :

  
GRAPH FILE TABLEHOLD
PRINT REJECTRATE AS ''
ACROSS EVENTDATETIME
BY STEPCODENAME
ON GRAPH SET LOOKGRAPH SCATTERS
ON GRAPH SET GRAPHEDIT SERVER
ON GRAPH SET BARNUMB OFF
ON GRAPH SET 3D OFF
ON GRAPH SET VZERO ON
ON GRAPH SET GRID OFF
ON GRAPH SET GRMERGE ON
ON GRAPH PCHOLD FORMAT PNG
ON GRAPH SET GRAPHSTYLE *

now I need to drill down this graph by using the STEPCODENAME column, how do I do this? Thanks.

I'm using WebFocus DevStudio 7.1.3.

You have DevStudio. You can just click on the tabs and follow the instructions.

Id your child fex ready with the needed amper variables?

You don't mention which graph tool you are using but assuming the Advanced Graph Assistant, click on the Y-axis field (REJECTRATE) and fill out the drilldown control using STEPCODENAME as a variable to pass to the child program.

The process is similar with the Graph Assistant using the field properties for the Y-axis field.

Make sure that your child program is written, debugged, and has a WHERE clause for STEPCODENAME.

Hi, thanks for your feedbacks.

Yes, sorry, I forgot to mention this, I got up to the "Drill Down Parameter" control, I choose DEFTRNSSTEPCODENAME as the parametername(the parameter name on the child fex, does it have to be the same name?), I choose Field as the parameter value but now here's where I'm having problem, the drop down menu only shows EVENTDATETIME and REJECTRATE.

Also, could you show me how to do this in the codes, I don't really like using the GUI, thanks in advance.
