VectorScale
- The following settings can be given for VectorScale:
-
| Automatic | automatic setting based on the location of field vectors |
| Large,Medium, Small, Tiny | scale field vectors to be large, medium, etc. |
| {unitlen,aratio,sfun} | use explicit specification of field vector scale |
- With the explicit specification VectorScale->{unitlen, aratio, sfun} each field vector is constrained to fit in a vector box oriented in the direction of the field, centered at the location of the vector.
- The unitlen is given as a fraction of the diagonal of the overall bounding box and is used as a local scale for vector boxes, aratio is the aspect ratio for vector boxes, sfun is a scaling function that determines the width of vector boxes.
- The following settings can be used for unitlen:
-
| s | unit scale to use, given as a fraction of the diagonal of the overall bounding box |
| Large,Medium,Small,Tiny | symbolic unit lengths |
- The following settings can be used for aratio:
-
| r | absolute aspect ratio relative to unitlen |
| Scaled[r] | relative aspect ratio for each vector box |
| Automatic | correspond to Scaled[1] in 2D and Scaled[0.6] in 3D |
- The following settings can be used for sfun:
-
| None | all vector boxes are unitlen wide |
| func | a function of x, y, fx, fy, Norm[{fx, fy}] |
| Automatic | use Norm[{fx, fy}] |
- When using an explicit sfun, positive values are automatically scaled to lie between 0 and 1. For other values the vector is not drawn.
Use symbolic names to control the size of vectors:
| Out[1]= |  |
Specify the relative size of vectors as a fraction of the diagonal of the plot range:
| Out[1]= |  |
With the vector scaling function set to None, then all vectors have the same size:
| Out[1]= |  |
