Crystal Reports Plotting Line Graph with mutipul series using grps

Message

     Hey Everyone,

I am having a bit of bother with creating a line chart in Crystal reports 10.

I a report created that shows me how many calls our support desk has processed each month depending on there call type.

I have done this by creating a group which shows calls for a speicifc date range dependant on there call type

e.g. 

PC fault

record 1

record 2

record 3

record 4

record 5

Printer fault

record 1

record 2

record 3

record 4

record 5

I have then used a summary function to  break this down into months e.g.

Printer fault 01/01/09

recrod 1
record 2

Printer fault 01/02/09

record 3
record 4
record 5

I have then created another summary which counts the number of calls logged.

e.g.

Printer fault 01/01/09

recrod 1
record 2

Calls for this period 2

Printer fault 01/02/09

record 3
record 4
record 5

Calls for this period 3

I want to create a graph that will show me how many calls were logged during each month for the various call types.

E.g. printer fault and pc fault as series

and no of calls going on the y axis 1,10,20,30,40,50 etc...

and the date range  e.g. 01/01/09, 01/02/09, etc...

I am relitavley new to crystal and was wondering if this was possible with the way the report currently works.

Many thanks

Warren
