The Windows screen coordinate system
has its origin in the upper left corner of the
screen with the positive x-axis pointing to the right and the positive y-axis pointing
down. This is the default coordinate system used by Meazure.
If you prefer using a more familiar coordinate system, select the
Invert Y item on the
View menu. This will
position the origin of the coordinate system in the lower left corner of the screen
with the positive x-axis pointing to the right and the positive y-axis pointing up.
