8.8 Polar Coordinates


Cartesian coordinates are normally used in the X-Y Plot. In the Cartesian coordinate system data
is drawn on a rectangular grid defined by the X and Y-axes. The scales of X and Y units do not
necessarily have to be the same, in fact they usually are not. Examples could be AFR on one
axis and manifold pressure, throttle position or RPM on the other.

The Polar coordinate grid system is circular and centered at the origin (intersection) of an x-y
coordinate system. The scale is the same in all directions. The values are shown as a distance
and a direction from the center. It could be thought of as a rotary bar graph. In this case the
center represents zero and the length and angle of the indicator line represents the magnitude
and vector (direction) of the measurement. Similar to a bull’s-eye shooting target where the score
is measured as distance from the center, but in this case the center is zero and further from the
center is a larger measurement.

A circular graph is useful when analyzing the “g” forces of acceleration, braking and turning left or
right that act at any direction in a horizontal plane relative to the vehicle. The forces are
measured by the X and Y axis accelerometers in the DL-32 or LMA-3 and the combined force
magnitude is represented as a distance from the center (no force) and it’s acting direction as the
angle of a line drawn from the center to the combined force point.

Polar Coordinate View can only be used (and only makes sense) if both X and Y

channels have the same unit.

To switch to polar coordinate view use:
