In order to use the chart effectively you must learn graphology online and the value of each of the dividing lines, which represents degrees of slant.  These rules follow:

1. Writing that is vertical or slants from A to B shows that judgment will rule.   The writer will meet emergencies without growing hysterical, and unless the circumstance is unusually emotionally disturbing, without showing any emotional reaction.   The vertical writer may be said to be ruled by the head rather than the heart.   However, writers who slant their writing to come under or close to B are not totally lacking in expression.   They may feel  deeply, but they do not show how they feel.

2. Writing that slants from B to C will be quick to respond sympathetically or in a mild way to emotional situations. They are not plungers, they do not impulsively break into a conversation, or act without some thought, especially if there is a matter of importance under consideration.

3. Writing that slants from C to D is evidence of a promptly and very expressive  individual.    Such writers will usually show traces of tears when speakers tell a particularly heart-rending story. They act promptly, and very often act or speak solely on impulse, and without thinking.

4. Writing that slants from D to E is evidence of extreme emotional response.  These are the writers who are whirlwinds as salesmen, lecturers, actors, writers, and in similar fields. They sweep everything before them, and then suddenly, and to themselves frighteningly, go sour or find that they cannot produce. This is true because they burn out emotional force, and are temporarily exhausted emotionally. It is a striking thing about such writers that even a minor surprise of a favorable nature will revive the emotional expression which is so vital to their relationships with others.

5. Writing that slants to the left of center is just the opposite of emotional expression. It reveals the writer who is not even judicial, but one who pulls back into self. He cannot be judicial, but instead is affected by self and self-interest, past normal self-interest. This rule is general, and you will learn about the ex­ceptions a little later. There is nothing difficult about recognizing the exceptions, so you can accept this rule as it is written, in a majority of cases.
