Setting X axis interval with categorical date variable [closed]

I have a dataframe as below:

enter image description here

I wish to plot date in x axis with a list that has exactly the number of date values as in the table and the record count for that date in y axis.

The code I am using (as shown below) gives the following syntax error:

File "<ipython-input-48-192c9d0a3a14>", line 5
    b==Rec_Cnt_BD010['Record_Count_BD010']
    ^
SyntaxError: invalid syntax

Any help is sincerely appreciated!

xaxisint=[202101,202102,202103,202104,202105,202106,202107,202108,202109,202110,202111,202112,202201,202202,202203,202204,202205,
         202206,202207,202208,202209,202210,202211,202212]
a==Rec_Cnt_BD010['Process']
b==Rec_Cnt_BD010['Record_Count_BD010']
ax=plt.axes()
plt.plot(a,b, kind='line', color='r', marker='x')
ax.set_xticks(xaxisint)
plt.axhline(y = Rec_Cnt_BD010[b].mean(), color = 'b', linestyle = '--', label='Mean')
plt.grid(True)
plt.xlabel('Date')
plt.ylabel('Record Count for BD010')
plt.legend()
plt.show()

Why is my reports service not connecting?

The number of nodes and edges I calculated manually and by a method provided by networkx library dont match

I am trying to analyse a graph using networkx library in Python. I have implemented a function that returns the nodes and edges of that graph. After that I counted the number of nodes and edges by implementing the len() function for nodes and edges, which gave me 17 for both nodes and edges. However, when I used the method graph.number_of_nodes() of networkx library it gave me 53. My code: import pandas as pd import networkx as nx import matplotlib.pyplot as plt header_list = ["a","b","w"] E =pd.read_csv("aves-barn-swallow-contact-network.edges",sep=" ",header= None,names=header_list) # print(E.head()) # prints first few rows of the csv file G = nx.from_pandas_edgelist(E,"a","b",["w"]) nx.draw(G) plt.show() class GraphAnalyse: #finding nodes and edges def nodeEdge(self,Graph): nodes = Graph.nodes() edges = Graph.edges() ...
