We could
choose each table one-by-one, but for a good start, checking the appropriate
Automatic layout checkbox is recommended. Doing this puts all the related
tables from our database onto the list of tables to be included in the schema. It
then generates appropriate coordinates so that the tables will appear in a spiral
layout, starting from the center of the schema. These coordinates are expressed in
millimeters, with (0,0) being located at the upper-left corner. We then click Go.
Editing a Page
We now get a page with three different sections. The first one is the master menu,
where we choose the page on which we want to work (from the drop-down menu);
we can also delete the chosen page. We could also, eventually, create a second
schema (page).

The next section is the table placement part. We now see the benefit of the Automatic
layout feature: we already have our three tables selected, with the (X,Y) coordinates
filled in. We can add a table (on the last line), delete a table (using the checkbox), and
change the coordinates (which represent the position of the upper-left corner of each
table on the schema):
To help set exact coordinates, a visual editor is available for JavaScript-enabled
browsers. To control the availability of this editor, the following parameter (which is
set to TRUE by default) is available:
$cfg['WYSIWYG-PDF'] = TRUE;
The editor appears when the Toggle scratchboard button is clicked once.
