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