When all data is in one direction, bar and pie show only one legend item.
Should show both legend items (even if one is not present in the chart)
How can this be fixed?

This is how it looks OK:
index.php/fa/31702/0/

This is how it looks WRONG:
index.php/fa/31701/0/

Attached are project files (I tried to delete most of the irrelevant code).
creatirea is: <amad>
either:
<amad>1</amad>
ot:
<amad>0</amad>

Hope this is clear and someone has a solution for this.

Many thanks
Yosi

Hi there. You probably need to build your data so you always have the series present even if there is no data for it.

for example, create a reference table that contains the values 'Right' and 'Wrong', then in your main query do an outer join based on the reference table so you always end up with a row for each category regardless of whether there is any data.

FWIW - I am an BIRT n00b, but I know a bit about SQL. The problem you are describing is a classic in SQL (for example, how do I make a query return sales per week even when there are no sales in a particular week. The easiest answer - use a reference table of weeks).
