[yt-users] Camera/Off Axis Options

[Suoqing Ji]

Hi Sushil,

> plt.streamplot(X[::factor, ::factor], Y[::factor, ::factor], U[::factor, ::factor], V[::factor, ::factor],norm='True’)

For stream plot, you can let factor = 1 or even delete [::factor, ::factor], since we want to construct streamlines for based on all data points. For quiver plot, we use this to draw quivers every “factor” number of data points only.

I should not have empty cells as all of the cells are filled like L(1,0,0) N(0,0,1).png. Since only the viewing angle is changed it should still fill all the cells.
