Styles¶

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

Resistor circle¶

Uses named colors in a loop.

../_images/styles_1_0.svg

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

Hand-drawn¶

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

../_images/styles_2_0.svg

import matplotlib.pyplot as plt
plt.xkcd()

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