Change the center position while using plot_2d function.

Hi yt Team, I am not able to change the centre position of the selection while plotting the density from a simulation output file using yt.plot_2d function. It is taking the domain centre as the centre value, even if I change it. I am also not able to change the origin of the output plot as well. Following is the code, please look into it. The output file is from amrvac code. It is the output of a 2.5 MHD code in spherical geometry. My domain centre values are [5.5 1.5707963267948966 0.5] code_length. Basically, r goes from 1 to 10 and theta from 0 to pi. path = "path" file = "filepath" ds = yt.load(file, geometry_override="Spherical_2.5D",parfiles= path + "amrvac.par", units_override = units_override, unit_system="mks") p = yt.plot_2d(ds,("gas","density"),center= [2.0,1.5707963267948966,0],width = (2.0,2.0)) after applying this, my plot range from 4.0 to 6.0 in x direction and from -1.0 to 1.0 in y direction. Please help. Thanks.

FLIP IN A MULTI PLOT
by FERNANDO ILLACANCHI GUERRA Feb. 27, 2024

Feb. 27, 2024

Hi Everyone, I have a simulation with an axis symmetry so i want to plor full simulation using the flip function. However, both plots are flipped in te resulting imagen. Is there a way to flip just one of them? Thanks in advance. for i in range(0,2): print(i) # Load the data and create a single plot ds = yt.load(fn) # load data p = yt.plot_2d(ds, ("Temp")) p.set_width((4,1)) if i == 1: p.flip_vertical() print("vertical") # This forces the ProjectionPlot to redraw itself on the AxesGrid axes. plot = p.plots[("Temp")] plot.figure = fig plot.axes = grid[i].axes plot.cax = grid.cbar_axes[i] # Finally, this actually redraws the plot. p.render() plt.savefig("multiplot_2x2_time_series.png")

Hello I am currently trying to install and setup yt on my laptop using the miniconda/anaconda/pip/whatever will work and I keep running into the issue of not being able to open my yt notebook. For pip/git it does not accept the command and for miniconda/anaconda it keeps giving me this error: Traceback (most recent call last): File "C:\ProgramData\miniconda3\Scripts\yt-script.py", line 10, in <module> sys.exit(run_main()) ^^^^^^^^^^ File "C:\Users\.\AppData\Roaming\Python\Python311\site-packages\yt\utilities\command_line.py", line 1613, in run_main args.func(args) File "C:\Users\.\AppData\Roaming\Python\Python311\site-packages\yt\utilities\command_line.py", line 223, in run self(args) File "C:\Users\.\AppData\Roaming\Python\Python311\site-packages\yt\utilities\command_line.py", line 1071, in __call__ from notebook.notebookapp import NotebookApp ModuleNotFoundError: No module named 'notebook.notebookapp' I have tried downloading various notebook software both onto this computer and from the conda install to no luck. I am stuck and would really appreciate help so I can resolve this issue. Thank you, Daniel

updating list of yt extensions and external frontends

Hi there! Do you use or maintain a yt extension or externally packaged frontend that is not part of the main yt package? I'm working on updating the docs to include a more current list so if you're aware of any not yet listed in https://github.com/yt-project/yt/issues/4824 I'd appreciate a note! Best, Chris

Dear yt Dev Team, Hope this email finds you well! I am writing to seek assistance regarding an issue I encountered while attempting to load vtk files. Specifically, I am trying to extract data from vtk files generated by athena simulations using the ds.load function. However, the code returned the following error message, Traceback (most recent call last): File "/home/wkal2/rds/hpc-work/project/code/plot.py", line 13, in <module> ds = yt.load(vtk_filename,parameters=parameters) File "/home/wkal2/ENTER/envs/ml/lib/python3.9/site-packages/yt/_maintenance/deprecation.py", line 69, in inner return func(*args, **kwargs) File "/home/wkal2/ENTER/envs/ml/lib/python3.9/site-packages/yt/loaders.py", line 144, in load return cls(fn, *args, **kwargs) File "/home/wkal2/ENTER/envs/ml/lib/python3.9/site-packages/yt/frontends/athena/data_structures.py", line 488, in __init__ Dataset.__init__( File "/home/wkal2/ENTER/envs/ml/lib/python3.9/site-packages/yt/data_objects/static_output.py", line 293, in __init__ self._parse_parameter_file() File "/home/wkal2/ENTER/envs/ml/lib/python3.9/site-packages/yt/frontends/athena/data_structures.py", line 572, in _parse_parameter_file self.domain_dimensions[2] = np.int32(1) ValueError: assignment destination is read-only I would greatly appreciate any insights you can provide on what might be causing this issue with the code. For your reference, I am using yt version 4.3.0. Thank you for your attention and I look forward to hearing from you! Best regards, Amelie Lam
