This article introduces the relevant knowledge of "how to use the line chart method plot () in matplotlib". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Definition and call of plt.plot ()

Definition:

Plt.plot (* args, scalex=True, scaley=True, data=None, * * kwargs)

Call:

Plot ([x], y, [fmt], *, data=None, * * kwargs)

Plot ([x], y, [fmt], [x2], y2, [fmt2],..., * * kwargs)

Location parameters:

[x], y, [fmt]

Keyword parameter transfer:

* the following parameters

Different types of x sequences

Text-type x sequence

# data X = [8Person3Person5Grampt'] # will be positioned on the scale of the x-axis in order [0Lie1JEI 2jin3] plt.plot (XPowerYLING = 'odynere cymbals') ax = plt.gca () print ('x-axis scale:', plt.xticks ()) # list xticklabels_lst = ax.get_xticklabels () print ('-'* 70)

X-axis scale: ([0,1,2,3],)

Print ('x-axis scale label:', list (xticklabels_lst)) # is a text label

X-axis scale label: [Text (0,0,8'), Text (1,0,3'), Text (2,0,5'), Text (3,0,'t')]

Digital x sequence

# data X = [8Yue3Power5Power1] # will be positioned on the scale of the x-axis by number [8pj3je 5jp1] on the scale of the x-axis Y = [1pje 2je 3je 4] plt.plot (XLI YLINGO = 'odyne parcels') ax = plt.gca () print ('x-axis scale:', plt.xticks ()) # array xticklabels_lst = ax.get_xticklabels () print ('-'* 70)

X-axis scale: (array ([0.1,2.,3.4.5.6.7.8.9]),)

Print ('x-axis scale label:', list (xticklabels_lst)) # is a text label arranged by serial number

X-axis scale labels: [Text (0.0,0,0'), Text (1.0,0,1'), Text (2.0,0,2'), Text (3.0,0,3'), Text (4.0,0,4'), Text (5.0,0,5'), Text (6.0,0,6'), Text (7.0,0,7'), Text (8.0,0) '8'), Text (9.0,0,9')]

2 types-2 Lin

# data X1 = [8pje 3pje 5pjt'] X2 = [8pje 3pje 5pje 1] Y = [1pje 2pas 3pje 4] plt.plot (X2pIe YLING = 'ooJing pencils') plt.plot (X1Med YLING = 'OOBLING') ax = plt.gca () print ('x-axis scale:', plt.xticks ()) xticklabels_lst = ax.get_xticklabels () print ('-'* 70)

X-axis scale label: [Text (0,0,8'), Text (1,0,3'), Text (2,0,5'), Text (3,0,'t')]

Provide a different number of location parameters

Several ways of calling

No parameter

# return an empty list plt.plot ()

[]

Plot ([x], y, [fmt], *, data=None, * * kwargs) plot ([x], y, [fmt], [x2], y2, [fmt2],..., * * kwargs)

1 parameter

# provide a number (point) plt.plot (4.5)

[]

# provide a numeric sequence plt.plot ([4.5pr 2p3], marker='o')

[]

2 parameters

The principle of automatic analysis of position parameters

(XBI y) form

# XPUBY is the sequence plt.plot ([2 mine1, 3], [0.5 dome 2 pr 2.5], marker='o')

[]

# XUnix y is a scalar plt.plot (2, ['z'], marker ='o')

[]

(ycmt) form

# plt.plot (2 recordings) # Unrecognized character z in format string# y is a scalar plt.plot (2)

[]

# y is the sequence plt.plot ([2jimi 1jue 3], 'rmurmuri stories')

[]

3 parameters

([X], y, [fmt]) form

Plt.plot ([2Jing 1jue 3], [0.5Jing 2Med 2.5],'p-murmur, # marker='o' markersize = 15)

[]

If # fmt does not write, or'', then the default style plt.plot is used ([2 mine1 marker='o' markersize 3], [0.5 mine2 min2 5],'', # meme = 15)

[]

Drawing Line2D

Draw lines only: default for drawing

Default style: blue [line] [unmarked]

# marker = None means that plt.plot is not set ([2meme2.5])

[]

Draw marks only

Plt.plot ([2, 2.5, 1],'o')

[]

Draw lines + marks

Plt.plot ([2mai 2.5jue 1], 'Omuri')

[]

Plt.plot ([2Jing 1jue 3], 'bo--')

[]

Is the combination order of fmt random?

6 the unity of pictures and conclusions

# 6 combinations # [color] [marker] [line], 3 arbitrary combinations are 6 possibilities # b: blue # o: circle mark # -: dotted line fmt = ['bo--','b--o','ob--','o--b','--bo','--ob'] for i in range (len (fmt)): plt.subplot (2) plt.plot ([2) Fmt [I]) # conclusion: [color] [marker] [line] Each is optional, and each attribute can choose to write or not write # regardless of the order in which they are located in the combination

[line]-line supported by fmt

Line Styles

Synthesis: line drawings marked with hollow circles

The use of data keyword

Dictionary data

# Dictionary data d = {'name':list (' abcd'), 'age': [22 name','age',ddata 20 18 abcd' 27]} plt.plot (' dictionary = d)

[]

DataFrame data

# DataFrame data d = {'name':list (' abcd'), 'age': [22 name':list 20, 18 DataFrame 27]} df = pd.DataFrame (d) dfnameage0a221b202c183d27plt.plot (' name','age',data = df)
