Quiver

A handy wrapper that allows somebody to quickly and easily plot equations, using Sympy and Matplotlib.

Motivation

When I was taking a differential equations course, as much time trying to program decent looking plots as actually working on the problems. I wanted to create a tool that would allow students and teachers to quickly plot direction fields, such as for a first order differential equation.

Example Usage

from quiver.plotter import FieldPlotter

plotter = FieldPlotter()
plotter.set_equation_from_string('x+y')
plotter.make_plot()

with open('plot_file.png', 'w+') as output:
    plotter.write_data(output)
