Hide parts of the chartlegend

[dking]

Hallo all together =),

I have a small question. I have 3 integer-fields and a XY Chart.

There are 2 series in the chart:

First:

Field a = x-Axie

Field b = y-Axie

Second:

Field a = x-Axie

Field c = y-Axie

The legend shows the discription of both series.

I want that the Legend have only 1 discription, if for example b have no data (=null).

 

Is that possible??

Hi,

 

I might not understand exactly what you mean, in which case it would be better if you could post some JRXML and some screenshots to better descriebe what you want to achieve.

 

But have you tried to use the same series name for your two points? It would appear as a single series.

 

I hope this helps.

Hi,

 

If you want your "blabla" series to not appear at all, if it has only null values, then you must "hide" it by giving it the same series name as "bla", in case the C field value is null.

Also, when the C field is null, the Y expression of your blablah series should actually return the B field.

This way, when the C field is null, the second series will actually behave like the first series and add the same points.

The first series will have its point duplicated, but this has no visual impact.

 

The series name for your second series should be something like:

 

$F{c} == null ? "blah":"blahbla"

 

while the Y expression should be:

 

$F{c} == null ?$F{c}:$F{b}

 

I hope this helps.
