Hello Matt,
Thanks, that seems to have done fixed the issue. I am seeing that the graph
looks very different now compared to before. Would forgetting the extra
zone change the appearance of the overall plot beyond edge effects?
Thank you,

Hi Nathan,
Yup, I agree with your assessment -- there's an edge effect. You need one more thing to get the derivative field working; you need to tell yt to give you an extra zone in each direction. You can do that by changing your decorator for the derived field to:
@derived_field(name = "GravGradientX", validators = [ValidateSpatial(1)])
I don't believe you need any additional changes inside the source code. Let us know if that fixes it!

Hello,
Using an Enzo dataset, I have written a function to find the derivative in the x-direction of a field. When I try to plot the derivative, I see

The attached plot is a slice of the x-direction derivative of the PotentialField viewed down the x-axis, but this error appears in plots for density and pressure as well. I am new to using yt, and I am not sure what is causing this.
Thank you, Nathan Butcher
