<DIV><FONT size=2><FONT face=Arial>Thanks John! Everything worked fine! Although
I agree with you in the fact that it's easier to use data object rather than a
dataset, I wondered If you could tell me why the
<STRONG>SetDataObject...Component(... , ...)</STRONG> function doesn't work fine
in my example and what's the difference between
<STRONG>SetDataObjectPlotModeToColumns</STRONG>() and
<STRONG>SetDataObjectPlotModeToRows</STRONG>(), since I don't know what
<STRONG>columns</STRONG> and <STRONG>rows</STRONG> these functions refer to
(I've already seen the HTML help).</FONT></FONT></DIV>
