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.
Property
|
Control Type: Values
|
---|---|
Grid units
|
String List: Set grid units type. Choose from:
Default = Not applicable
|
Vector style
|
String List: Set vector style type. Choose between these values:
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:
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
![]() 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:
Default = Nearest neighbor
|

|
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)
