[FIXED] How to apply different functions to the same plot using matplotlib.pyplot?

Issue

I am trying to plot a graph on python using the function matplotlib.pyplot and it seems that when I run the codes, they apply but to separate graphs. So when I applied plt.scatter(Lt, T) it showed the graph, then when I applied plt.xlabel('Local Time (hours)') it did run but to a new graph without the data inputed when I ran put.scatter(Lt,T) so basically I get a plain graph with only an x-axis title.

import matplotlib.pyplot as plt
plt.scatter(L, T)
plt.axis([0,25,200,800])
plt.xlabel('Local Time')
plt.ylabel('Surface Temperature')
plt.title('Surface Temperature vs. Local Time')

I expect all the codes and functions to apply to the same graph.

Solution

I think you need use the show method. You usually add this at the end after you've defined the axes etc. Sometimes it makes sense to wrap it in a function like below.

import matplotlib.pyplot as plt

def plotter(L,T):
    plt.scatter(L, T)
    plt.axis([0,25,200,800])
    plt.xlabel('Local Time')
    plt.ylabel('Surface Temperature')
    plt.title('Surface Temperature vs. Local Time')
    plt.show()

plotter(L,T)

Hope that helps.
