Instantiating TChart without a form?

Has anyone tried to instantiate a TChart in code,
and without a form as its parent? I tried something
similar to this:

MyChart := TChart.Create(nil);
MySeries := TBarSeries.Create(nil);
MySeries.Parent := MyChart;
{add values to series here}

and then saved the chart as a metafile, but the file
ends up empty.

(Oh, and yes, I did set all the various values like
width, height, etc. before saving the metafile).

If anyone's successfully done this in code, a snippet
would be appreciated!

Thanks and Happy Holidays,
