The Electric Field Direction Perpendicular to the Dipole Axis

EANDM-F8MCA4

Figure 1 below depicts an electric dipole. The field point $P$ in this figure lies along the line parallel to the $\hat{x}$ axis, which is perpendicular to the dipole axis. The dipole axis is collinear with the $\hat{y}$ axis.
