pandas.Series.plot

函数原型

Series.plot(kind='line', ax=None, figsize=None, use_index=True, title=None, grid=None, legend=False, style=None, logx=False, logy=False, loglog=False, xticks=None, yticks=None, xlim=None, ylim=None, rot=None, fontsize=None, colormap=None, table=False, yerr=None, xerr=None, label=None, secondary_y=False, **kwds)

注：要使用plot函数需要使用matplotlib和pylab环境。%matplotlib inline

参数

参数	类型	说明
kind	str	‘line’:默认值。线性图。例：tz_counts[:20].plot(kind=’line’, rot=0) ‘bar’：垂直条形图。例：tz_counts[:20].plot(kind=’bar’, rot=0) ‘barh’：水平条形图。例：tz_counts[:20].plot(kind=’barh’, rot=0) ‘hist’：柱状图。例：tz_counts[:20].plot(kind=’hist’, rot=0) ‘box’：box plot。例：tz_counts[:20].plot(kind=’box’, rot=0) ‘kde’：核密度估计Kernel Density Estimation(KDE) ‘density’：和’kde’相同 ‘area’：面积图。例：tz_counts[:20].plot(kind=’area’, rot=0) ‘pie’：饼图。例：tz_counts[:20].plot(kind=’pie’, rot=0)
ax	matplotlib axes object。matplotlib轴对象	如果未传参，使用gca()
figsize	元组tuple (width, height)	图片尺寸。参数类型为一个元组。单位为英寸
use_index	布尔值。默认值为True	是否使用Series的index作为x轴标识。
title	string or list	图标的标题。如果这个参数北传递进来，这个标题将显示在图片的顶部。如果一个list被作为参数传递进来并且 If a list is passed and subplots为True, 打印列表中的对象到相应的subplot.
grid	boolean, default None (matlab style default)	是否显示网格。
legend	False/True/’reverse’	是否在图上显示坐标轴说明
style	list or dict	matplotlib line style per column
logx	boolean, 默认值为False	Use log scaling on x axis
logy	boolean, 默认值为False	Use log scaling on y axis
loglog	boolean, 默认值为False	Use log scaling on both x and y axes
xticks	sequence	Values to use for the xticks
yticks	sequence	Values to use for the yticks
xlim	2-tuple/list	Rotation for ticks (xticks for vertical, yticks for horizontal plots)
ylim	2-tuple/list
rot	int, default None
fontsize	int, default None	xticks和yticks的字体大小
colormap	str or matplotlib colormap object, default None	Colormap to select colors from. If string, load colormap with that name from matplotlib.
colorbar	boolean, optional	If True, plot colorbar (only relevant for ‘scatter’ and ‘hexbin’ plots)
position	float	定义条形图条形形状的相对位置。取值范围是0~1。0代表left/bottom-end，1代表right/top-end，默认值是0.5(中间)
table	boolean, Series or DataFrame, default False	If True, draw a table using the data in the DataFrame and the data will be transposed to meet matplotlib’s default layout. If a Series or DataFrame is passed, use passed data to draw a table.
yerr	DataFrame, Series, array-like, dict and str	See Plotting with Error Bars for detail.
xerr		same types as yerr.
label		label argument to provide to plot
secondary_y	boolean or sequence of ints, default False	If True then y-axis will be on the right
mark_right	boolean, default True	When using a secondary_y axis, automatically mark the column labels with “(right)” in the legend
kwds	keywords	Options to pass to matplotlib plotting method

线图

垂直条形图

水平条形图

柱状图

box图

面积图

饼图

返回值

axes : matplotlib.AxesSubplot or np.array of them

注意

如果kind = ‘bar’ or ‘barh’, 可以通过position关键字定义条形图的相对布局。 取值范围是0~1。0代表：left/bottom-end；1代表：right/top-end。缺省是0.5 (center)。
