Layout problem with (dynamic) images

The report is made from within visual studio 2010 (C#).
I have to make the report which shows scores, retreived from a dataset.
These scores should be shown in horizontal way, like the picture attached.
This dataset has two datatables containing a parent(id,name) and a child subset (id, parent_id, score, score_expected)
Each parent can have a max of 4 scores.
I could draw this table as boxes in separate sections and suppress them with formulas, but I can't find a way to create the arrows(=score_expected).
Creating this 'table' is a hell of work with formula's and not very dynamic to extend (when needed)
I guess this is the right subforum, because I don't find any other crystal subforum.
Does anyone know a way to solve my problem?

Have you tried a horizontal bar graph.

Use the scores as data points and the expected as markers ?

If you have the knowledge, flash might work.

Just some ideas.

I didn't try a horizontal bar, but still no way to put the arrows above the rows.
For the moment I'm trying another report engine.
