Series in chart, but not in legend

SvenW

Hello,

i have a chart with a series A, B and C.
All series are shown in the chart and also in the legend, but i only want series A and B in the chart.

Is it possible to "delete" an entry in the legend?

Thanks in advance
Sven

I do not think this is supported, certainly not by the out-of-the-box configuration wizard. You could probably affect the entries in the legend via the Scripting API.

you could do it through custom event handler . Use beforeDrawSeries(Series series, ISeriesRenderer isr,
IChartScriptContext icsc) event to hide the chart dynamically. Incase you want to modify legend look into beforeDrawLegendItem(LegendEntryRenderingHints
lerh, Bounds bounds, IChartScriptContext icsc)

I tried this before, but i don't know how to skip rendering my legend entry item.
My chart is ok, it's just about the legend.

In my Java class i can set the caption of the entry item, but i can't get rid of the color.

I would prefer to prevent rendering my item, but before drawing i can't remove that item (or i don't know how).

Some background info:
I got a stacked column, consist of 3 parts.
Example:
Series A = 10
Series B = 20
Series C = sum of the other = 30

The value of the parts are displayed inline, besides series C it's displayed above my column.
It's filled dynamically from my Java class and series C is divided by 10000 in my class. In Birt the displayed value is multiplyed by that number. So i got the value above my column as a sum and the part is not displayed, just the value.
I hope you understand, what i want to achieve.

Hi Sven,

The enclosed example uses script to remove a legend item. Hope this helps.
