These properties control contour object visualizations. For each property, the type of control and the values that can be assigned are listed. For a description of how a particular control is used, refer to Property Controls.

Table D-45: Contour Properties

Table D-45: Contour Properties
Property | Control Type: Values
--- | ---
Contour level properties | User Defined: Click to edit individual or all contour level properties. Click and Edit... to display the Contour Levels window. See Contour Levels Window for details.
Use palette color | Boolean: Use palette color? Choose True or False. Default = False
Planar Z Value | Number: Z value of plane on to which to project contours. Edit the number to change the value. Note - If the Z value is zero, and the Projection is Planar, then the contour visualization is considered to be 2D. If the Z value is nonzero, then the contour visualization is considered to be 3D, and the dataspace associated with this contour will be automatically switched to 3D. Default = `0`
Number of levels | Number: Number of contour levels to display. Edit the number to change the value. Default = `5`
Projection | String List: Method of projection. Select a method from the list. Choose from these values: Three-D: Project in three dimensions Planar: Project onto a plane Default = Planar
Fill contours | Boolean: Fill space between contours? Choose True or False. Default = False
Shading | String List: Shading method. Select a method from the list. Choose between these values: Flat: Flat shading Gouraud: Gouraud shading Default = Flat
Minimum value | Number: Minimum value to display in the contour. Edit number to change value. No default value.
Maximum value | Number: Maximum value to display in the contour.Edit number to change value. No default value.
Downhill ticks | Boolean: Show downhill ticks? Choose Hide or Show. Default = Hide
Downhill tick interval | Number: Distance between downhill tick marks. Edit number to change value. Default = `0.2`
Downhill tick length | Number: Length of downhill tick marks. Edit number to change value. Default = `0.2`

Label interval | Number: Distance between labels on the contour level. Edit number to change value. Default = `0.4`
No label gaps | Boolean: Interrupt the contour level for the label. Choose True or False. Default = False
Use label color | Boolean: Display a color for the contour level's label. Choose True or False. Default = False
Label color | Color: Color for the contour level label. Click to choose from the default color palette, or specify RGB values. Default = `[0,0,0]` (black)
Symbol label | Symbol: Symbol to appear at regular intervals on the contour level. Choose a symbol from the list. Default = No symbol
Symbol size | Number: Factor from 0 - 1 determining the size of the selected symbol. Move slider to change the size. Default = `0.2`
