Restricting the range with xmin and xmax doesn't work with parametric plot. Here's the code,
cs_01 = parametric_plot([fresnel_cos(t), fresnel_sin(t)], (t, -1.5*pi, 1.5*pi), ticks=[pi/8, 0.2], tick_formatter=[pi, None], axes_labels=['$x(t)$', '$y(t)$'], axes_labels_size=1.5, plot_points=500, xmin=-pi/4, xmax=pi/4, ymin=-0.8, ymax=0.8, fontsize=12)
cs_01_text_01 = text(r'$x(t) = \int_0^t\cos(\frac{\pi u^2}{2})du$', (-pi/2,0.8), fontsize=13, color='black', bounding_box={'boxstyle':'round', 'fc':(0.9,0.9,0.9), 'ec':'w'})
cs_01_text_02 = text(r'$y(t) = \int_0^t\sin(\frac{\pi u^2}{2})du$', (-pi/2,0.4), fontsize=13, color='black', bounding_box={'boxstyle':'round', 'fc':(0.9,0.9,0.9), 'ec':'w'})
cs_01_text_03 = text('Clothoid or Cornu spiral', (0, 1.15), fontsize=14, color='black', fontweight='bold')
cs_01 + cs_01_text_01 + cs_01_text_02 + cs_01_text_03
But when provided within show it works,
cs_01 = parametric_plot([fresnel_cos(t), fresnel_sin(t)], (t, -1.5*pi, 1.5*pi), ticks=[pi/8, 0.2], tick_formatter=[pi, None], axes_labels=['$x(t)$', '$y(t)$'], axes_labels_size=1.5, plot_points=500, ymin=-0.8, ymax=0.8, fontsize=12) + \
text(r'$x(t) = \int_0^t\cos(\frac{\pi u^2}{2})du$', (-pi/2,0.8), fontsize=13, color='black', bounding_box={'boxstyle':'round', 'fc':(0.9,0.9,0.9), 'ec':'w'}) + \
text(r'$y(t) = \int_0^t\sin(\frac{\pi u^2}{2})du$', (-pi/2,0.4), fontsize=13, color='black', bounding_box={'boxstyle':'round', 'fc':(0.9,0.9,0.9), 'ec':'w'}) + \
text('Clothoid or Cornu spiral', (0, 1.15), fontsize=14, color='black', fontweight='bold')
cs_01.show(xmin=-pi/4, xmax=pi/4)
I don't know why it's happening. Is it supposed to work like that?
