This plot is in memory of vintage racer Dick Ott, who was the driver/owner of the car during
recording of this log.
In this example right turning and accelerating are assigned positive values and left turning and
braking are negative.
Even though Polar coordinates are essentially value and angle, by convention the normal
cartesian axis labels are used to make the view easier for a novice to interpret.
Polar Coordinate View imposes the following restrictions:
a. Zooming will always happen in both axis.
b. No auto scale in X-axis allowed.
c. Only channels with the same unit are allowed for the axis
8.8.1 Marker Lines in Polar View
Vertical and horizontal Marker Lines (limit indicators or redlines) do not apply in a Polar
Coordinate View. Instead, a perimeter limit marker, the dashed blue line in the example above,
defines an elliptical shape formed by quarter-elliptical segments between the four markers on the
horizontal and vertical axes, consisting of (clockwise):
a. The max. marker position in the vertical direction (12:00 o’clock) and max. marker
position in the horizontal direction (3:00 o’clock).
b. The max. marker position in the horizontal direction (3:00) and min. marker in the vertical
direction (6:00).
c. The min. marker in the vertical direction (6:00) and min. marker in the horizontal direction
(9:00).
d. The min. marker in the horizontal direction (9:00) and max. marker in the vertical direction
(12:00).
