Polar Graph Settings
Use this dialog to make changes to the visual background attributes of a polar graph.

Axis Properties
These properties modify the appearance of the axis lines, which are drawn from the graph center/origin at the listed angles.

Axis List (Degrees) - Use this list box to add, modify, and delete the axis lines which are drawn from the graph center/origin at the listed angles. All axis angles must be in degrees. All angles not in (0 <= Angle < 360) will be rotated to their equivalent angle in this range. For example, "365" will become "5", and "-10" will become "350". This control will not accept constant mathematical expressions such as "3+4", and "90*(Pi/180)". Only simple real numbers such as "180", and "-64.409" are allowed. The list is cleaned and sorted when it looses the input focus, or the dialog closes. A maximum of 360 axis lines are allowed.

Standard Axis Lists - This button opens the standard axis list dialog, used to automatically create the most commonly used axis list angles.

Axis Color - Opens a dialog to change the axis line color. Current color is displayed in the sample rectangle.

Axis Line Width - Changes the width of the axis lines.

Axis Line Style - Select from the following line styles Solid, Dash, Dot, Dash Dot, or Dash Dot Dot.

Background Color
Color button opens a dialog to change the background color. Current color is displayed in the sample rectangle.

Graph Radius
When the "Restrict Radius" option is checked the length of the background axis lines is restricted to the radius specified in the edit line. This setting affects only the axis lines and their associated tick marks; it does not effect polar functions drawn on the graph. Must be a valid constant mathematical expression (in graph units); greater than zero.

Tick Mark Properties
Two types of tick marks are can be used to add a sense of scale to the graph. Dashes are short lines along each axis. Circles cross each axis line in the same spots as dashes, and are centered at the origin.

Increments - Distance between each tick mark dash, or circle radius (in graph units). Must be a valid constant mathematical expression; greater than or equal to zero.

Color - Opens a dialog to change the tick mark color. Current color is displayed in the sample rectangle.

Tick Mark Type - This property selects the tick mark type, choices are "Dashes", "Circles", or "None".

Circle Style - This property only takes effect when "Tick Mark Type" is set to "Circles". Select from the following circle styles Solid, Dash, Dot, Dash Dot, or Dash Dot Dot.

Dash Length / Circle Width / No Tick Marks - The title and usage of this scroll bar changes when the "Tick Mark Type" property changes. When "Dashes" is selected the tick mark dash length can be changed. Dash width is always the same as "Axis Line Width". When "Circles" is selected the circle width can be changed. When "None" is selected the title changes to "No Tick Marks", and the scroll bar has no effect.

Label Properties
Use these settings to change the appearance of the numeric tick mark labels.

Show Labels - Enables/Disables drawing of the tick mark labels.

Format Combo Box – Selects the label format type.

"," – Inserts commas into numbers. Example: 1,000,000

"+" – Puts a plus sign in front of all positive numbers. Example: +12.5

Decimal Places - Maximum number of decimal places for each tick mark label.

Font - Opens a dialog to change the tick mark label font.
