Jasper Woes

Hi,

I have just started working with iReport. Everything seemed
straightforwars until I tried to add a simple line graph. I use a csv
file like this:

XAxis,YAxis
1,2
2,4
3,6
4,8

What I expect to get is one graph that plots all 4 points and draws a
line between each two. What I get is 4 seperate graphs with all 4
points with no lines.

I tried playing with grouping to no avail...in short, I tried a whole
bunch of things, but got nowhere.

Below is the JRXML file.

Any tips would be appreciated!

Forgot to mention: using iReport 1.3.3

OK, realized I should try creating groups, added a Name column to
group by, and also tried grouping by XAxis. I now get 4 identical
graphs, where each graph is what I want. Progress...
