uitableview - iphone: custom UITableViewCell taller than the default cell view -

I am creating a list that contains a listView with 5 rows: - with a graph - from 1 to 2 5 rows have some data with the same formatting.

I have created 2 squares: graphicviewviewsell and dataCustomViews. Based on the position of the cell, I load the correct customcell as:

  NSArray * topLevelObjects = [[NSBundle mainBundle] loadNib named: @ "GraphCustomViewCell" owner: zero option: zero]; (ID current object in TopLevelObjects) {if ([currentObject isKindOfClass: [GraphCustomViewCell class]]) {cell = (GraphCustomViewCell *) currentObject; break; }}  

It works fine except for the first line, corresponds to the graph, 4 other rows in the larger (in height), and as the result it hides the first 3 other rows.

Is there a choice in the table view that enables the custom cell to expand into the default cells? I like 5 rows (graph + 4 data lines) to fit the whole screen (480 - tabbar height)

Thank you very much for your help Regards, Luke
