Locators for tick on axisΒΆ

An example demoing different locators to position ticks on axis for matplotlib.

plot ticks
import numpy as np
import matplotlib.pyplot as plt
def tickline():
plt.xlim(0, 10), plt.ylim(-1, 1), plt.yticks([])
ax = plt.gca()
ax.spines["right"].set_color("none")
ax.spines["left"].set_color("none")
ax.spines["top"].set_color("none")
ax.xaxis.set_ticks_position("bottom")
ax.spines["bottom"].set_position(("data", 0))
ax.yaxis.set_ticks_position("none")
ax.xaxis.set_minor_locator(plt.MultipleLocator(0.1))
ax.plot(np.arange(11), np.zeros(11))
return ax
locators = [
"plt.NullLocator()",
"plt.MultipleLocator(1.0)",
"plt.FixedLocator([0, 2, 8, 9, 10])",
"plt.IndexLocator(3, 1)",
"plt.LinearLocator(5)",
"plt.LogLocator(2, [1.0])",
"plt.AutoLocator()",
]
n_locators = len(locators)
size = 512, 40 * n_locators
dpi = 72.0
figsize = size[0] / float(dpi), size[1] / float(dpi)
fig = plt.figure(figsize=figsize, dpi=dpi)
fig.patch.set_alpha(0)
for i, locator in enumerate(locators):
plt.subplot(n_locators, 1, i + 1)
ax = tickline()
ax.xaxis.set_major_locator(eval(locator))
plt.text(5, 0.3, locator[3:], ha="center")
plt.subplots_adjust(bottom=0.01, top=0.99, left=0.01, right=0.99)
plt.show()
