Matplotlib data analysis of a histogram Python

A: example of histogram:

Import numpy AS NP
 Import matplotlib.pyplot AS plt 


# polyline charts 
# AX = [23,26,28,31,32,33] # just creates a data 
# AY = [3.0,3.5,4.0,3.0,3.5, 4.0] 
# plt.plot (AX, AY, color = 'R & lt', as linewidth =. 1, u'1 label = ') # color line color specified, the contents of the label lABEL 
# plt.legend (LOC = 2) label placement # , with the tag numbers represent positions 
# plt.xlabel (u'X / deg.] C ') 
# plt.ylabel (u'Y /') 
# plt.title (u'2019 / 06/07 ') 
# # set each axis the range (x-axis value, y-axis values) 
# plt.axis ([0,36,0,8]) 
# plt.show () 




# bar graph 

# num_list = [for 1.5, 0.6, 7.8, 6] 
# plt.bar(range(len(num_list)), num_list,fc='r')
# plt.show()



# 堆叠柱状图
# name_list = ['Monday','Tuesday','Friday','Sunday']
# num_list = [1.5,0.6,7.8,6]
# num_list1 = [1,2,3,1]
# plt.bar(range(len(num_list)), num_list, label='boy',fc='y')
# plt.bar(range(len(num_list)), num_list1, bottom=num_list, label='girl',tick_label = name_list,fc ='r')
# plt.legend()
# plt.show()



# 并列柱状图
# name_list = ['Monday','Tuesday','Friday','Sunday']
# num_list = [1.5, 0.6, 7.8,6] 
#num_list1 = [1, 2, 3, 1]
# x = list(range(len(num_list)))
# total_width, n = 0.8, 2
# width = total_width / n
#
# plt.bar(x, num_list, width=width, label='boy', fc ='y')
# for i in range(len(x)):
#     x[i] = x[i] + width
# plt.bar(x, num_list1, width=width, label='girl', tick_label=name_list, fc='r')
# plt.legend()
# plt.show()



# 条形柱状图
name_list = ['Monday','Tuesday','Friday','Sunday']
num_list = [1.5,0.6,7.8,6 ] 
plt.barh (Range (len (num_list)), num_list, tick_label = NAME_LIST) 
plt.show () 




'' ' 
set a background color: 
    1. FC: setting a uniform color (Example : fc = 'r' uniform red) 
    2. color: color not provided (Example: color = 'rgb', three colors recycling) 
    3. settings tab: 
        NAME_LIST = [ 'catalog on Monday', 'on Tuesday', 'catalog on Friday' , 'the Sunday'] 
        plt.bar (Range (len (num_list)), num_list, FC = 'R & lt', tick_label = NAME_LIST) 
'' '
