Suppress 0 in line graph

Suppress 0 in line graph

Suppress 0 in line graph

I've set up a line graph in Crystal 8.0.  When the graph encounters a blank record (value is NULL not 0), the graph displays properly as long as I'm running the report within Crystal Report Designer - you don't see a data point for that record.  The line discontinues at this point and then picks back up with the next record that has a valid number in it.   

Here's the problem - I'm calling this same report from VB 6.0.  HOWEVER, the blank record that was not being displayed running from Crystal is now showing as a 0.  So now my line graph dips all the way down to 0 before going to the next valid record.  It's messing up my graph because it appears as if these records have a 0 instead of being NULL.  

Any ideas?  I'm clueless on this one.  I assumed that a Crystal Report graph would display the same regardless of whether it's being called from VB or running with Crystal but it appears that it doesn't.  Thanks in advance!

RE: Suppress 0 in line graph

Do you want the records that contain the NULL value? If not you could type in 'NOT ISNULL({fieldname})' in the record selection.


RE: Suppress 0 in line graph

Well, for that particular graph I want the records that do not contain a null value, but since I have other information I need on that same record, I don't want them excluded.  

For example, in a given record I have Blood Pressure, Weight, and Height.  I have graphs for all 3 of these.  I can't exclude the records with no weight because that same record COULD have a height that I need to see.

RE: Suppress 0 in line graph

Instead of using not isnull{{field}) in your record select, maybe it would work if you just replaced the problem field with a formula and used this for graphing:

if not isnull({field}) then {field}

This would preserve the record, since other fields from that record are being used elsewhere. I'm not sure this will work, but it might be worth a try.
