Programmatically Suppressing Graphs in Crystal Reports

I'm using Crystal Reports to create some graphs. I'm linking students in a report showing a graph of results for each subject

Student

Ian Smoth UREL5 U TU

Course

UREL5 5 9 23 33 23 6 1

LREL5 10 13 23 27 20 7

Dependent on whether the the course is an Upper or Lower course I want to give them a different graph, as the axis change. You can see that LREL5 doesn't have the same number of fields.

Is there a way in Crystal Reports to suppress the display of a graph if certain criteria is met?

I'm looking to do the following in the 'Formula Workshop':

if {All_Students_txt.Qual Level} = "U" then
   suppress LowerGraph
else
   suppress UpperGraph

Alternatively I could mess about with dynamically upd开发者_如何学JAVAating the graph on each record

You might want to create a separate section for each graph (right click the section and choose Insert Section Below), then suppress the appropriate section. This approach gives you more flexibility.

The suppression formula for the 'upper' section would be:

{All_Students_txt.Qual Level} <> "U"

The suppression formula for the 'lower' section would be:

{All_Students_txt.Qual Level} = "U"
