fxruby users - Feb 2008 - Drawing rotated text.

Hi,
I''m using a FXPNGImage to draw chart elements (axis, data, labels,
lines).
But, to draw axis title, that need to be vertical at left and right, how can
I rotate the text?
I think the solution is to create a image item for each string I want to
draw, and render these images at the outer device context. But it
doesn''t
work.
Some helps to do this?
Thanks,

These are the steps:

	1) make a new font (name, size, etc).
	2) Set the angle at which you want to draw the text; this is specified
	   in degrees * 64, i.e. 90 degrees is 5760.
	3) Realize or create() the font.
	4) Draw your text.

	FXChart draws axes etc. also.  Even though its done in C++, I think
	it may be useful to look at.  Eventually FXChart (and subclasses)
	will become a suite of various types of plotting controls. 


Hope this helps,
