4 /// This macro makes use of some basic graphics primitives such as line, arrow
5 /// and text. It has been written using the TCanvas ToolBar to produce a first
6 /// draft and was then modified for fine adjustments. Note also the use
7 /// of C functions. They allow to simplify the macro reading and editing by
8 /// avoiding code repetition or defining some graphics attributes in one single
9 /// place. This technique to generate drawings may appear not very user friendly
10 /// compare to all the "wysiwyg" graphics editors available. In some cases it can
11 /// be more powerful than a GUI interface because it allows to generate very
12 /// precise drawing and using computation to generate them.
