Thank you, it works now, but another error occurs from example CVS manual. But I
am not ask about it since it is CVS version.
Until now, I am still considering to learn tikz by reading manual and type the
examples. However, since there may be error from example in manual, I would like
to ask suggestions how to learn tikz reach the level of finishing all of the
tutorials.
Thank you in advance.
Regards,
