Figure D-17: Visualization Browser with Vector Properties Displayed

These properties control vector 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-47: Vector Properties 

Table D-47: Vector Properties 
Property
Control Type: Values
Grid units
String List: Set grid units type. Choose from:
  • Not applicable
  •  

  • Meters
  •  

  • Degrees
Default = Not applicable
Vector style
String List: Set vector style type. Choose between these values:
  • Arrows
  •  

  • Wind barbs
Default = Arrows
Length scale
Number: Length. Enter value.
Default = 1
Head size
Number: Head size. Enter value.
Default = 1
Arrow style
String List: Set arrow style type. Choose between these values:
  • Lines
  •  

  • Filled
Default = Filled
Proportional heads
Boolean: Make arrow heads proportional? Choose True or False. Default = False
Arrowhead angle
Number: Arrowhead angle value. Enter value.
Default = 30
Arrowhead indentation
Number: Arrowhead indentation value. Enter value.
Default = 0.4
Arrow thickness
Number: Arrow thickness level. Choose value 1 through 10.
Default = 2
Line thickness
Number: Line thickness level. Choose value 1 through 10.
Default = 1
Data location
Boolean: Select location along arrow for data. Choose Tail, Center, or Head. Default = Center
Automatic color
Boolean: Select color setting. Choose None, Magnitude, or Direction. Default = Magnitude
Color
Color: Color for arrows. Click to choose from the default color palette, or specify RGB values. Default = [0,0,0] (black)
Color palette
Color: By selecting Edit color table Edit access the color table to manipulate vector color values
Note - To edit the opacity only in the editor, uncheck the R, G, and B boxes in both the Modify and Display rows. Edit the remaining line by clicking on and dragging the line in the window. Click OK when finished.
Transparency
Number: Percent transparency. Move slider to change value.
Default = 0
Minimum magnitude
Number: minimum magnitude. Enter value.
Default = None
Maximum magnitude
Number: maximum magnitude. Enter value.
Default = None
Z value
Number: Z value of plane on to which to project the vector visualization. Edit the number to change the value.
Note - If the Z value is zero then the vector visualization is considered to be 2D. If the Z value is nonzero, then the vector visualization is considered to be 3D, and the dataspace associated with this vector will be automatically switched to 3D.
Default = 0
Automatic subsampling
Boolean: Automatically subsample the vector visualization? Choose True or False. Default = False
Subsampling method
String List: Set subsample type. Choose between these values:
  • Nearest neighbor
  •  

  • Linear
Default = Nearest neighbor
X subsampling factor
Number: Subsample factor in the x direction.
Default = 1
Y subsampling factor
Number: Subsample factor in the y direction.
Default = 1
Mark missing points
Boolean: Automatically mark missing points? Choose True or False. Default = False
Direction convention
Boolean: Choose direction convention. Select Polar, Meteorological, or Wind azimuths. Default = Polar (counterclockwise from X axis)
