How to control the spacing between legend items?

I have a compound report that has 3 reports and 3 pie graphs. Each Pie graph has different amount of slices, but each pie graph does its best to distribute the legend out along the right side of the graph. This looks odd when you look at the entire compound report and you see different amount of spacing in the legend for each graph.

Any suggestions on how to stop the graph engine from distributing the legend items? Ideally, I would like the legend to start at the top of the legend area and each item to be immediately below the previos one.

Thanks In Advance!

Hi Jack,

By using the following function you can place your legend any where in the Graph u want.

setRect(getLegendArea(),new Rectangle(&x,&y,&w,&h));

where x = x-axis Co-ordinates.
Y = y-axis Co-ordinates.
W = Width.
H = Height.
give the values as per as your Graph Size.

Thanks,
Kalyan

Kalyan -
I will give this another try, but the cardinality of the data may vary per customer, so I have to select an arbritary size for the legend rectangle. Unfortunately, the graph engine wants to spread my legend items out to use the entire rectangle. So, if I have 3 items graphed the spacing is larger between items then if I have 4 items graphed. Seems like there should be an option to not distribute the items.

I guess I could determine the quantity of items in the data and derive some logic to dynamically set the legend rectangle size, but this seems like alot of hoops to jump through.

Do you have setPlace(true) in your code?

If yes, that's what causes your rectangle to adjust based on the number of series.
We need setPlace(true) to do some adjustment in graph by default but you can set that to false for the methods we need. For example, in your case you can do it by giving this method

setPlaceResize(getLegendArea(),false)

then you can make the rectange dynamically as you want.

Hope this works out for you,
