Hello I'm new here, I hope someone can help me :)
I'm trying to understand how to make a plot, which has a secondary axis, bigger. I tried with plt.figure() but didn't work. Also would like to know how to adjust the x-axis, for example using something like this plt.xticks(rotation=45).

I'm working with this example I found online:

# Adding a Y-Axis Label to
# the Secondary Y-Axis in Matplotlib
# importing the libraries
import pandas as pd
import matplotlib.pyplot as plt
 
#creating dataframe for plot
dataset = pd.DataFrame({'Name':['Rohit', 'Seema',
                                'Meena', 'Geeta',
                                'Rajat'],
                         
                   'Height': [155,129,138,164,145],
                   'Weight': [60,40,45,55,60]})
 
# creating axes object and defining plot
ax = dataset.plot(kind = 'line', x = 'Name',
                  y = 'Height', color = 'Blue',
                  linewidth = 3)
 
ax2 = dataset.plot(kind = 'line', x = 'Name',
                   y = 'Weight', secondary_y = True,
                   color = 'Red',  linewidth = 3,
                   ax = ax)
 
#title of the plot
plt.title("Student Data")
 
#labeling x and y-axis
ax.set_xlabel('Name', color = 'g')
ax.set_ylabel('Height', color = "b")
ax2.set_ylabel('Weight', color = 'r')
 
#defining display layout
plt.tight_layout()
 
#show plot
plt.show()
