<p>应将线添加到绘图中,然后显示:</p>
<pre><code>In [13]: import matplotlib.pyplot as plt
In [15]: from matplotlib.lines import Line2D
In [16]: fig = plt.figure()
In [17]: ax = fig.add_subplot(111)
In [18]: x = [10,24,23,23,3]
In [19]: y = [12,2,3,4,2]
In [20]: line = Line2D(x, y)
In [21]: ax.add_line(line)
Out[21]: <matplotlib.lines.Line2D at 0x7f4c10732f60>
In [22]: ax.set_xlim(min(x), max(x))
Out[22]: (3, 24)
In [23]: ax.set_ylim(min(y), max(y))
Out[23]: (2, 12)
In [24]: plt.show()
</code></pre>
<p>结果是:</p>
