Dear Suoqing Ji:
I was able to implement the off axis using velocity field (drive link below). My script yt_velocity_fields.py plots for a normal vector (L=0,1,0) in the x-z plane (figure L010.png) which is correct.
But for an azimuth angle of say 45 degrees (L=1,0,1) it gives me a plot L101.png which is not what I am looking for.
I would like to view the same plot L010.png but at an azimuth of 45 degrees (in the x-z plane).
Could you let me know if there is any error in my script or any suggestion for the same?
PS: While running the script I do get a runtime warning which is below
Thanks in advance

Hi Sushil,
Thanks for reporting this! I?ve filed an issue here: https://bitbucket.org/yt_analysis/yt/issues/1213/annotate_magnetic_field-fai... < https://bitbucket.org/yt_analysis/yt/issues/1213/annotate_magnetic_field-fai...
In the meanwhile, you could temporarily circumvent this problem by loading your dataset as velocity field and use ?annotate_velocity?...

I am trying to get a z-x plane and view it at an angle of 15,45,60

Hi Sushi,
What you need to do this to make use of off-axis slice plot instead of
camera; for example, in your code:
L = [1, 0, 0] # View along x axis north_vector = [0, 0, 1] slc = yt.SlicePlot(pf, L, ?magnetic_field_x", width=(100,'km?),
north_vector=north_vector)
slc.annotate_magnetic_field(factor=40, normalize=True)
which gives you the view along x axis. And if you want to rotate the
viewing angle by, say 45 degree, you could change the normal vector L to be L = [1, 1, 0], and redo the plotting.
Also, when you load the data, you probably need to change the name
?field_x? to be ?magnetic_field_x? and so on, so the annotate_magnetic_field function will recognize these names.
Best wishes,

Dear Suoqing Ji:
The fields Bx,By and Bz are already calculated taking into account the
rotation. So I am not sure if I need to calculate it again.
What I would like is only change the camera view to a desired angle
after I do a slice plot and that is where I am having trouble with?
Thanks in advance.

Right, I bet it will work if you do `annotate_velocity()` though.
You should take a look at the definition of the VelocityCallback to
see how it handles off-axis slices.

Hi Sushi,
The quiver/streamline option you?ve used works for 2d plotting but
not for volume rendering, so I might suggest to use off-axis slice plot: http://yt-project.org/doc/visualizing/plots.html#off-axis-slices < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices%3E < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices%3E%3E < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices%3E < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices < http://yt-project.org/doc/visualizing/plots.html#off-axis-slices%3E%3E%3E
Unfortunately, quiver/streamline does not work (and/or does not
work correctly) for off axis slice plot now, but your goal is still achievable via the following steps:
Are you sure about that? There's a `CuttingQuiverCallback` for
off-axis slices. If you do `annotate_magnetic_fields`, it will automatically choose the `CuttingQuiverCallback` for off-axis slices.
- Use fixed resolution buffer to get the off-axis sliced field
values including Bx, By and Bz (see this as an example, and replace SlicePlot with OffAxisSlicePlot: http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... < http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... < http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... < http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... < http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... < http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... <http://yt-project.org/docs/dev/cookbook/complex_plots.html?highl ight=fixedresolutionbuffer#multi-plot-slice-and-projections < http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre...), then you get a 2D array for each field;
- Compute the magnetic field vectors projected onto the rotated
viewing plane (perpendicular to your normal vector), based on field values of Bx, By and Bz; now you have two 2D arrays for each components of B field vectors after rotation;
- Use quiver function in matplotlib and plot the B field vectors
after rotation, see: http://matplotlib.org/examples/pylab_examples/quiver_demo.html < http://matplotlib.org/examples/pylab_examples/quiver_demo.html%3E < http://matplotlib.org/examples/pylab_examples/quiver_demo.html < http://matplotlib.org/examples/pylab_examples/quiver_demo.html%3E%3E < http://matplotlib.org/examples/pylab_examples/quiver_demo.html < http://matplotlib.org/examples/pylab_examples/quiver_demo.html%3E < http://matplotlib.org/examples/pylab_examples/quiver_demo.html < http://matplotlib.org/examples/pylab_examples/quiver_demo.html%3E%3E%3E
Hope this helps! Perhaps there?s an easier way that I do not know...

Hi Sushi,
I think the off-axis slice/projection plot will meet your
requirement best, where the camera orientation is determined by the normal vector:

And of course, if you?re interested in the features provided by
volume rendering, it?s also worth a try. This cookbook gives an example of moving a camera; specifically you might want to use the camera.rotation:

Hi Sushil,
Your code looks good to me at the first glance — maybe you could try to add the argument such as “center=[0, 0, 0]" in SlicePlot call, to make sure the slice will cut through the region you want to inspect? With a random field data, I can not reproduce this on my laptop.
Also, Kacper has fixed the issue of B field annotation (https://bitbucket.org/yt_analysis/yt/pull-requests/2146/create-vector-fields...), and you could use it as soon as this pull request gets merged.

Dear Suoqing Ji:
I was able to implement the off axis using velocity field (drive link below). My script yt_velocity_fields.py plots for a normal vector (L=0,1,0) in the x-z plane (figure L010.png) which is correct.
But for an azimuth angle of say 45 degrees (L=1,0,1) it gives me a plot L101.png which is not what I am looking for.
I would like to view the same plot L010.png but at an azimuth of 45 degrees (in the x-z plane).
Could you let me know if there is any error in my script or any suggestion for the same?
PS: While running the script I do get a runtime warning which is below

Hi Sushil,
Thanks for reporting this! I?ve filed an issue here: https://bitbucket.org/yt_analysis/yt/issues/1213/annotate_magnetic_field-fai... https://bitbucket.org/yt_analysis/yt/issues/1213/annotate_magnetic_field-fails-with-off <https://bitbucket.org/yt_analysis/yt/issues/1213/annotate_magnetic_field-fai... https://bitbucket.org/yt_analysis/yt/issues/1213/annotate_magnetic_field-fails-with-off>
In the meanwhile, you could temporarily circumvent this problem by loading your dataset as velocity field and use ?annotate_velocity?...

Hi Sushi,
What you need to do this to make use of off-axis slice plot instead of camera; for example, in your code:
L = [1, 0, 0] # View along x axis north_vector = [0, 0, 1] slc = yt.SlicePlot(pf, L, ?magnetic_field_x", width=(100,'km?), north_vector=north_vector) slc.annotate_magnetic_field(factor=40, normalize=True)
which gives you the view along x axis. And if you want to rotate the viewing angle by, say 45 degree, you could change the normal vector L to be L = [1, 1, 0], and redo the plotting.
Also, when you load the data, you probably need to change the name ?field_x? to be ?magnetic_field_x? and so on, so the annotate_magnetic_field function will recognize these names.
Best wishes,

Dear Suoqing Ji:
The fields Bx,By and Bz are already calculated taking into account the rotation. So I am not sure if I need to calculate it again.
What I would like is only change the camera view to a desired angle after I do a slice plot and that is where I am having trouble with?
Thanks in advance.

Right, I bet it will work if you do `annotate_velocity()` though.
You should take a look at the definition of the VelocityCallback to see how it handles off-axis slices.

Unfortunately, quiver/streamline does not work (and/or does not work correctly) for off axis slice plot now, but your goal is still achievable via the following steps:
Are you sure about that? There's a `CuttingQuiverCallback` for off-axis slices. If you do `annotate_magnetic_fields`, it will automatically choose the `CuttingQuiverCallback` for off-axis slices.
- Use fixed resolution buffer to get the off-axis sliced field values including Bx, By and Bz (see this as an example, and replace SlicePlot with OffAxisSlicePlot: http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedresolutionbuffer#multi-plot-slice-and-projections <http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedresolutionbuffer#multi-plot-slice-and-projections> <http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedresolutionbuffer#multi-plot-slice-and-projections <http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedresolutionbuffer#multi-plot-slice-and-projections>> <http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedresolutionbuffer#multi-plot-slice-and-projections <http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedre... http://yt-project.org/docs/dev/cookbook/complex_plots.html?highlight=fixedresolutionbuffer#multi-plot-slice-and-projections> <http://yt-project.org/docs/dev/cookbook/complex_plots.html?highl http://yt-project.org/docs/dev/cookbook/complex_plots.html?highl

Compute the magnetic field vectors projected onto the rotated viewing plane (perpendicular to your normal vector), based on field values of Bx, By and Bz; now you have two 2D arrays for each components of B field vectors after rotation;
Use quiver function in matplotlib and plot the B field vectors after rotation, see: http://matplotlib.org/examples/pylab_examples/quiver_demo.html http://matplotlib.org/examples/pylab_examples/quiver_demo.html <http://matplotlib.org/examples/pylab_examples/quiver_demo.html http://matplotlib.org/examples/pylab_examples/quiver_demo.html> <http://matplotlib.org/examples/pylab_examples/quiver_demo.html http://matplotlib.org/examples/pylab_examples/quiver_demo.html <http://matplotlib.org/examples/pylab_examples/quiver_demo.html http://matplotlib.org/examples/pylab_examples/quiver_demo.html>> <http://matplotlib.org/examples/pylab_examples/quiver_demo.html http://matplotlib.org/examples/pylab_examples/quiver_demo.html <http://matplotlib.org/examples/pylab_examples/quiver_demo.html http://matplotlib.org/examples/pylab_examples/quiver_demo.html> <http://matplotlib.org/examples/pylab_examples/quiver_demo.html http://matplotlib.org/examples/pylab_examples/quiver_demo.html <http://matplotlib.org/examples/pylab_examples/quiver_demo.html http://matplotlib.org/examples/pylab_examples/quiver_demo.html>>>

My script is yt_cam_rot.py. Without the camera options I get the desired plot (UniformGridData_Slice.png) but when I use the camera I get a empty screen. I am not sure where I am going wrong.

Hi Sushi,
I think the off-axis slice/projection plot will meet your requirement best, where the camera orientation is determined by the normal vector:

And of course, if you?re interested in the features provided by volume rendering, it?s also worth a try. This cookbook gives an example of moving a camera; specifically you might want to use the camera.rotation:
