Hi Christian, If I am following Slack right, I think this got resolved -- or is there more we should do to help out? On Tue, Jul 26, 2022 at 7:55 AM Christian van der Merwe via yt-users < yt-users@python.org> wrote:
Hi all,
I am very new to YT and I have been trying to create a line plot for my GADGET-4 simulation output, but I keep running into a problem.
I try to do a similar plot as that found here: https://yt-project.org/doc/cookbook/simple_plots.html#simple-1d-line-plottin.... I want to be able to 'draw' an arbitrary line and see how a quantity such as density changes along that line. My script and an example snapshot is linked below with the error I am getting following after.
The code: http://paste.yt-project.org/show/392/ The snapshot and code: http://use.yt/upload/6dd0e0b8 YT version: 4.0.4
I keep getting this traceback error:
