7.2.12 Number of Vectors Across
The panel item called Number of Vectors Across lets you specify
how many vectors (of the magnitude specified by Standard Vector
Magnitude) you think ought to fit across your current image area.
You may have to experiment with it to determine the best value to use.
Rules of thumb:
- If you are happy with what you get with the default settings,
DON'T USE THIS. Just leave it at zero or it will only become
- If you are plotting UNGRIDDED vectors, use only this item to alter the
size of the vectors. Standard Vector Magnitude can be left at
- If you need to calibrate two disparate vector datasets to the same
scale, SET BOTH Number of Vectors Across and Standard Vector
Magnitude and use the same values for all datasets. These two
values represent the quantities that SatView uses internally to
compute the size of the vectors. If you set them manually, you will
have complete control. If you leave either one at zero, SatView will
take its best guess at a reasonable value (for each dataset).
- If you are confused, leave them both at zero. The drawback with
using this panel item is that you will need to change it each time you
zoom in or out. So unless you have a good reason to set it manually
(and many people will), you should just leave it at zero.
