Basic of Plot

Drawing multiple lines and plots

You encounter many situations in which you must use multiple plot lines, such as when comparing two sets of values. To do that, you simply call plt.plot() multiple times. You will see multiple plot lines with different colors.

Let's try to plot the number of hurricane in 2005 and 2015.

Formatting the axes

Note that instead of number, we want the x-axis to be the names of the months. You can use .xticks for this. Note that we need to flatten the DataFrame into a list using .flatten().

To further change the axes, we need to assign a variable for axes, here we use ax. There are many things we can do with that, like showing grid using .grid()

Changing Line Appearance

Line styles help differentiate the graphs. Here are the character representing the line styles:

• '-' : Solid Line
• '--' : Dashed Line
• '-.' : Dash-dot Line
• ':' : Dotted Line

We try to change the grid to dotted lines, 2005 into solid line, and 2015 into dashed line.
