        <pre>When you select a full column for data series in graphics, the rendering of the
graphing is very slow and the file becomes huge, although the total data is
tiny

To reproduce
------------

new calc file
enter numbers in A1, A2, B1, B2
create a new graph
Select a full column as series data (say $Sheet1.$A:$A, you must edit manually,
calc does not let you select a whole comuln)

Everything becomes very slow. When saving, it makes a 3 MB file

In my case, it happened after converting an EXCEL file.

Wished behavior
---------------
The graphics engine should restrict the data selection to the actualy used
range of the sheet</pre>
