Piechart can anyone verify this?

2005-09-01 02:29

I'm tring to et a simple piechart work in the new version with no luck the way I want it...

 

Select * where ClientAccount = 1 and Date = "2005-09-01"

 

From this I choose

 

Fields

 

ClientAccount Integer

MetalCode String

MetalValue Double

 

 

These are going in a piechart to show the respetive share of metalvalue against total value of the

client account. The label of each piece in the chart is the MetalCode.

 

What I try to do is this.

 

I make one report series to the MetalValue and one to the label eg MetalCode.

These definitions look like this

 

 

Name = SERIE_MetalValue

Variable classtype = Double

Calculation Type = SUM

 

Variable Expression

((it.businesslogic.ireport.IReportScriptlet)$P{REPORT_SCRIPTLET}).addValueToSerie($V{SERIE_MetalValue},$F{MetalValue})

 

Name = SERIE_MetalCode

Variable classtype = String

Calculation Type = Nothing

 

Variable Expression

$F{MetalCode}

 

 

These two go into the piechart in the following way.

Under the chartproperties/chartdata/details

I put this.

 

Key expression

$F{AccountId}

 

Valueexpression

$V{SERIE_MetalValue}

 

Labelexpression

$V{SERIE_MetalCode}

 

Now done!

 

I try and run it
