Python Question

I have the data:

`x = [10,24,23,23,3]`

y = [12,2,3,4,2]

I want to plot it using

matplotlib.lines.Line2D(xdata, ydata)

I use

`import matplotlib.lines`

matplotlib.lines.Line2D(x, y)

But how do I show the line?

Answer Source

You should add the line to a plot and then show it:

```
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()
```

The result:
