Description

A polar plot is the plot of data expressed in polar coordinates, with radius r as a function of angle θ.

The radius r is the distance from the central point and θ is the angle from the x-axis:

The Polar plot dialog box

• Radius: a variable containing the Radius data
• Angle: a variable containing the Angle data
• Filter: an optional filter to include a subset of data in the plot
• Options
  • Angle unit: select whether the values for Angle are expressed in Radians (1 circle = 2 PI) or Degrees (1 circle = 360°), or are Percentages (1 circle = 100).
  • Rotation: the plot can be rotated clockwise of counterclockwise
  • Zero angle: the angle origin can be North, East, South or West.
  • Connect points: an option to connect consecutive points in the plot.
