You can try this:
y=function('y',x) var('x,yy,z') f=xy+x^2-y^3x ff=f.diff(x).subs({y.diff(x):z,y:yy}) implicit_plot3d(ff,(x,-3,3),(yy,-3,3),(z,-4,4))

You can try this:
y=function('y',x)
f=xy+x^2-y^3var('x,yy,z')var('x,yy,z')xxff=f.diff(x).subs({y.diff(x):z,y:yy})ff=f.diff(x).subs({y.diff(x):z,y:yy})
implicit_plot3d(ff,(x,-3,3),(yy,-3,3),(z,-4,4))

You can try this:
y=function('y',x) y=function('y',x) var('x,yy,z')
f=xy+x^2-y^3x
ff=f.diff(x).subs({y.diff(x):z,y:yy})
implicit_plot3d(ff,(x,-3,3),(yy,-3,3),(z,-4,4))

You can try this:
y=function('y',x)
var('x,yy,z')
f=x*y+x^2-y^3*x
ff=f.diff(x).subs({y.diff(x):z,y:yy})
implicit_plot3d(ff,(x,-3,3),(yy,-3,3),(z,-4,4))
This way you avoid the "solve" issue.
