The result is:

This page shows how to draw vector field (electric field lines) using plotly. The figure is converted from matplotlib.pyplot.

Draw electric field lines without Mayavi

The result is:

Draw continuous electric field lines with sliced potential plane in 3D using Python Plotly

The result (static image) is:

Draw electric field lines with changing line color according to the electric potential

The results are:

This page shows how to draw electric force lines around point charges.
The colors of the electric force lines vary according to the electric potential in the point.

Draw flow past cylinder with continuous stream line using Python Matplotlib.pyplot

The result is:

This page shows how to plot air flow past a cylinder with continuous streamline or how to plot vecter field with continuous streamline. The air flow i.e. vecter field is calculated using COMSOL Multiphysics.

Plot continuous magnetic field lines using Python Matplotlib.pyplot

The result is:

This page introduces how to replot the normal stremplot or stremaline with continuous streamplot or stremline.

Plot electric field lines around a point charge with grounded sphere using Python Matplotlib.pyplot

The result is :

This page shows the method to draw electric field line around a point charge adjecent to a grounded sphere using method of image charges.

Draw electric field lines due to point charges using Python Matplotlib.pyplot

The results are:

and

This code shows how to visualize streamlines with continuous lines using python and matplotlib.pyplot.

When you search "electric field lines python" or something in Google, you would see the images which use the streamplot. Although it is easy way to visualize the direction of the vector fields, electric field must be continuous lines as you know. In this page, electric field lines around the point charges are calculated using scipy.ode (ordinary differential equations) module.

This code is based on following wonderful tips blog posts:

• Number Crunch
• Visualizing streamlines
