If the HDF file contains two datasets of the same size, it is possible to generate a vector field with these two sets. Typically these two data sets contains two velocity components.
To visualize your data as a vector field:
First, select the vector view menu option. Note that this option is only enabled when the HDF file contains two or more data sets with the same dimension.
Tip: Select the tree item that has the horizontal component of the velocity.
Now, you must choose the two velocity components. Just click on the listed SDS on the dialog and press Ok.
The SDS map vector options are similar to the SDS scalar map options. There is one aditional dialog option for the vector field and the Draw option has some extra features.
The vector options dialog box lets you choose the scale of the vectors, to define a value for the legend, and to choose the space between grid cells that each vector is drawn.
The Draw options of the vector view are similar to the scalar view. The user can choose to draw some basic features of the map. These are the arrow representing the vector, the rectangular grid, and the magnitude of each vector as a color. It is also possible to invert this palette.
