Python内联线标签

Question

对于我在Python中的计算模型，我有一个至少有50条不同线条的图。我尝试给他们不同的颜色/结构，但你可以理解它变得相当复杂，不易理解。

我认为最好的解决方案是将标签放在线条内。此处已有相关主题（How can I draw inline line labels in matplotlib?，Print string over plotted line (mimic contour plot labels)，Inline labels in Matplotlib）， 但是，由于我有许多相互交叉的线，并且我没有特定的x，y坐标（线条是用公式生成的），有没有办法自动找到放置线条标签的“最佳”位置？

这是我目前的绘图代码：

#plotting the figure and labels
fig = plt.figure()
ax = plt.subplot(111)
fig.patch.set_facecolor('white')
ax.set_axis_bgcolor('lightgrey')
plt.ylabel('State Activation')
plt.xlabel('Time')
plt.axis([0, time, 0, 1.2])
ax = plt.subplot(111)

# Hide the right and top spines
ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)

# Only show ticks on the left and bottom spines
ax.yaxis.set_ticks_position('left')
ax.xaxis.set_ticks_position('bottom')
plt.tight_layout()
