You don't have to label X and y on the axis but it's useful information. If you are ever struggling on what you should put on each axis then remember that the dependent variable (the one that always stays the same in this case the drink) goes on the X axis and the independent variable (the one that can change in this case the amount of people voting for each drink) goes on the Y axis..

Finally remember to always space out your bars otherwise it is an entirely different type of graph.
Find out the total frequency then divide 360 degrees by that number. The answer is called the magic number. You multiply the frequency of each section by the magic number to find out how many degrees are in each section.
Measuring the first section is simple especially if the magic number is 90 in this case you could just draw a straight line seeing as it's 180 degrees but measure it anyway.
Make sure you turn your protractor when measuring each different angle.
The last section is already drawn so you then just have to label the sections if you haven't already done so and if you want you can write the number of degrees in each section in the section.
