How do I plot a some dots with a trendline in pyplot?

Great question ! Plot ting a tr end line in Py plot is a straightforward process . Here ' s how you can do it : \n 1 . Import the necessary libraries : You will need to import the ` mat plotlib . py plot as plt ` library to use the ` plot ()` function . \n 2 . Create a list of data points : You will need to create a list of data points that you want to plot . For example , you could create a list of numbers that represent the height s of different objects . \n 3 . Plot the data points : Use the ` plot ()` function to plot the data points on the graph . You can use the ` x ` and ` y ` parameters to specify the x - axis and y - axis values for each data point . \n 4 . Add a tr end line : Once you have pl otted the data points , you can add a tr end line to the graph using the ` tr end ()` function . This function takes in a list of x - values and a list of y - values , which it uses to create a linear or polynomial tr end line . \n Here is an example of how you could plot a tr end line in Py plot : \n ``` \n import matplotlib . py plot as plt \n # Create a list of data points \n x = [ 1 , 2 , 3 , 4 , 5 ] \n y = [ 2 , 4 , 6 , 8 , 1 0 ] \n # Plot the data points \n pl t = plt . plot ( x , y ) \n # Add a tr end line \n t = plt . tr end ( x , y ) \n # Show the plot \n pl t . show () \n ``` \n In this example , we create a list of data points with x - values and y - values , and then use the ` plot ()` function to plot the data points on the graph . We then use the ` tr end ()` function to add a tr end line to the graph , and finally use the ` show ()` function to display the plot . \n I hope this helps ! Let me know if you have any other questions . </s>
