X:  Y:   Title of  X, Y axis
----------------------------

| Title of X or Y axis is defined as

.. container:: minipage angel-doublebox

   ``X:`` or ``Y:`` strings

| 

These strings are shown in the middle of X or Y axis. The blanks before the strings and after strings are neglected.

| The parameters which move the position of the titles, neglect them, and change the scale are explained in the following table. These parameters are defined in the parameters section P:.
