Do your electric field and equipotential lines appear as expected?

The question is incomplete. Let me explain the relationship between electric field and equipotential lines.

The electric field lines point symmetrically away from the positive point charge, this clearly indicates that they are perpendicular to the equipotential lines.

Explanation:

The potential for a point charge is V =

where k is a constant with value of 8.99 x 109 N m2/ , and r is the distance from point charge.

This shows that the potential for a point charge is the same anywhere on an imaginary sphere of radius r surrounding the charge.

The attached image is an isolated positive point charge Q and its electric field lines.

In the image, the electric field lines radiate out from a positive charge and terminate on negative charges.

The blue lines indicates the magnitude and the direction of the electric field.

This clearly helps us to see that the electric field lines point away from the positive point charge, which means that they are perpendicular to the equipotential lines.
