I generated a pie chart using iReport and when I went to preview mode, it spat out lots of useless pie charts (i.e. 1 chart with 1 of the 4 categories, next chart with 2 of the 4 categories, and so on… until a total of 3 charts are reached). My query is completely fine. When I tested the query on the DB (which is also the data source, it gave me:
category count
A 2
B 1
C 3
D 3
What do I need to do to get a proper pie chart with all 4 categories in it>
This page has my answer, except increment and reset settings also must be set properly in addition to what’s listed there:
