When opening an excel spreadsheet containing graphs, the graph horizontal axis
labels are not converted properly.  For example, in one graph, the horizotal
axis is labeled from 1 to 24 (hours of day) in Excel, but when opened in Calc,
it shows the word "Row" in each and begins with 2 instead of 1.  The graph is a
bar graph, with two bars at each data point, each with a different color.  In
Excel, the Legend shows "Node 1" and "Node 2" by the respective colors while in
Calc, it shows "Column H" and "Column S".

I would attach a copy of the Excel spread sheet, but don't see a way to attach
it to the case.

I'm using OO 2.0 beta, release 1.9.104.
