下面是我的代码：

# Graph for both infections and closures
# # plotting the points  
plt.plot(graph_date, graph_daily_infections, label = "Infections per day")
plt.plot(graph_date, graph_total_infections, label = "Infection overall")
plt.plot(graph_date, graph_daily_closure, label = "Closures per day")  
plt.plot(graph_date, graph_total_closure, label = "Closure overall") 
# # naming the x axis 
plt.xlabel('Date') 
# naming the y axis 
plt.ylabel('Number of Infections/Closure') 
# giving a title to my graph 
plt.title('Daily infections and closure overtime \n Infection Rate: {0} | Closure Threshold: {1}'.format(infectionRate,closeThreshold)) 
# show a legend on the plot
plt.legend()
# # changing the scale of the x ticks at the bottom
# # plt.locator_params(nbins=4)
# # set size of the graph
plt.rcParams["figure.figsize"] = (20,15)
# # function to show the plot
plt.show()

字符串
这段代码的问题是，当显示日期时，它们在x轴上被挤压在一起。
有没有办法只显示月份，或者只显示月份和年份？图表应该显示数据的时间间隔是4个月，所以只显示月份/年份和月份是理想的。谢谢！
