[yt-users] Derivative Error

[Nathan Butcher]

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 lines
that throughout the plot that I'm guessing are due to the edges of cells.
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
