Matplotlib plot Label along plot line
One for the matplotlib community:
Let's say I have a straight line:
plot([37, 45], [-0.67778, -0.67778], '--k', lw=1.2)
Is it possible to add a label to this line along the line and not to the legend? that is, something similar to the following (but not a contour plot, just a regular line plot):

Below is an example to show how this can be done without considering appearance. For more information on annotations see this detailed demo .
import matplotlib.pyplot as plt
x = [37, 45]; y = [-0.67778, -0.67778]
# as an example for where to place the text we can use the mean
xmean = sum(i for i in x) / float(len(x))
ymean = sum(i for i in y) / float(len(y))
plt.plot(x, y, '--k', lw=1.2)
plt.annotate('some text', xy=(xmean,ymean), xycoords='data')
plt.show() # or plt.savefig('filename.png')
