如何在Python中绘制我的目的图？
在Python中，我想使用：从 pylab 导入*
然后使用该模块中提供的plot。然而，我绘制的曲线不是我想要的：
说出两个列表：x = [1, 2, 3, 4]y = [1.4, 5.6, 6, 3.5]
我正在寻找一种可以绘制以下图表的绘图方法：
绘制一条连接点的线：(1, 0) 和 (1, 1.4)
绘制一条连接点的线：(2, 0) 和 (2, 5.6)
绘制一条连接点的线：(3, 0) 和 (3, 6)
绘制一条连接点的线：(4, 0) 和 (4, 3.5)
...
即：它应该像图形一样绘制光谱，例如R中的plot(x, type='h')。我想我使用的绘图方法只是通过线连接所有点。那么，就我的目的而言，请选择哪些方法？谢谢！！
in python, I would like to use:from pylab import *
Then use plot provided in this module. However, the curves I plot were not what I want:
Say two lists:x = [1, 2, 3, 4]y = [1.4, 5.6, 6, 3.5]
and I am after a plot method that can plot the following chart:
Plot a line that joins the points: (1, 0) and (1, 1.4)
Plot a line that joins the points: (2, 0) and (2, 5.6)
Plot a line that joins the points: (3, 0) and (3, 6)
Plot a line that joins the points: (4, 0) and (4, 3.5)
...
i.e.: it should plot a spectra like graphs, such as plot(x, type='h') in R. I suppose the plot method I use just joins all the points by lines. So, for my purpose, which methods to choose please? thanks!!

也许您只想要垂直线？您可以使用
vlines(x, [0], y)。请参阅此 示例您还可以查看此 页面（屏幕截图）可帮助您选择正确的函数。
Maybe you want just vertical lines? You could use
vlines(x, [0], y). See this exampleYou could also have a look at this page (screenshots) to help you select the right function.
您是指条形图吗？如果是这样，只需使用
bar函数：Do you mean a bar chart? If so, just use the
barfunction:
