streamslice¶
- Axes3DGL.streamslice(*args, **kwargs):
Plot stream lines slice in 3D axes.
- Parameters
x – (array_like) X coordinate array.
y – (array_like) Y coordinate array.
z – (array_like) Z coordinate array.
u – (array_like) U component of the arrow vectors (wind field).
v – (array_like) V component of the arrow vectors (wind field).
w – (array_like) W component of the arrow vectors (wind field).
xslice – (list) X slice locations.
yslice – (list) Y slice locations.
zslice – (list) Z slice locations.
density – (int) Streamline density. Default is 4.
- Returns
Streamline slices
