matplotlib-label-lines
Easily label line(s) using matplotlib.
The code is heavily based on http://stackoverflow.com/questions/16992038/inline-labels-in-matplotlib (original code from NauticalMile).
Install
Just do:
bash pip install matplotlib-label-linesYou can try it online on binder
, get some inspiration from the example or from the following script:
```python
import numpy as np
from matplotlib import pyplot as plt
from scipy.stats import chi2, loglaplace
from labellines import labelLine, labelLines
X = np.linspace(0, 1, 500) A = [1, 2, 5, 10, 20] funcs = [np.arctan, np.sin, loglaplace(4).pdf, chi2(5).pdf]
plt.subplot(321) for a in A: plt.plot(X, np.arctan(a * X), label=str(a))
labelLines(plt.gca().get_lines(), zorder=2.5)
plt.subplot(322) for a in A: plt.plot(X, np.sin(a * X), label=str(a))
labelLines(plt.gca().get_lines(), align=False, fontsize=14)
plt.subplot(323) for a in A: plt.plot(X, loglaplace(4).pdf(a * X), label=str(a))
xvals = [0.8, 0.55, 0.22, 0.104, 0.045] labelLines(plt.gca().get_lines(), align=False, xvals=xvals, color="k")
plt.subplot(324) for a in A: plt.plot(X, chi2(5).pdf(a * X), label=str(a))
lines = plt.gca().getlines() l1 = lines[-1] labelLine( l1, 0.6, label=r"$Re=${}".format(l1.getlabel()), ha="left", va="bottom", align=False, backgroundcolor='none' ) labelLines(lines[:-1], yoffsets=0.01, align=False, backgroundcolor='none')
labelLines also supports log-scaled x-axes
plt.subplot(325) for a in A: plt.semilogx(X, np.arctan(5 * a * X), label=str(a))
labelLines(plt.gca().get_lines(), zorder=2.5)
plt.subplot(326) for a in A: plt.semilogx(X, chi2(5).pdf(a * X), label=str(a))
labelLines(plt.gca().get_lines(), xvals=(0.1, 1), zorder=2.5)
plt.show()
