Styles

Circuit elements can be styled using Matplotlib colors, line-styles, and line widths.

Resistor circle

Uses named colors in a loop.

d = schemdraw.Drawing()
for i, color in enumerate(['red', 'orange', 'yellow', 'yellowgreen', 'green', 'blue', 'indigo', 'violet']):
    d += elm.Resistor().theta(45*i+20).color(color).label('R{}'.format(i))
d.draw()

Hand-drawn

And for a change of pace, activate Matplotlib’s XKCD mode for “hand-drawn” look!

import matplotlib.pyplot as plt
plt.xkcd()

d = schemdraw.Drawing(inches_per_unit=.5)
d += (op := elm.Opamp())
d += elm.Line().left().at(op.in2).length(d.unit/4)
d += elm.Line().down().length(d.unit/5)
d += elm.Ground()
d += elm.Line().left().at(op.in1).length(d.unit/6)
d += elm.Dot()
d.push()
d += (Rin := elm.Resistor().left().at((op.in1[0]-d.unit/5, op.in1[1]))
      .label('$R_{in}$', 'bottom')
      .label('$v_{in}$', 'left'))
d.pop()
d += elm.Line().up().length(d.unit/2)
d += (Rf := elm.Resistor().right().length(d.unit).label('$R_f$'))
d += elm.Line().down().toy(op.out)
d += elm.Dot()
d += elm.Line().left().tox(op.out)
d += elm.Line().right().length(d.unit/4).label('$v_{o}$', 'right')
d.draw()
