Part One: Title , The first part of the bar graph is the title, which is usually at the top. On this bar graph, the title is 'Chris's Snack Stand Sales, Spring 2015.' This tells us that data is only about sales at a specific time: spring 2015.

Part Two: Labels , Below the graph is the label ' Kind of Snack,' and above it you see labels listing the snacks Chris sold: chocolate bars, soft pretzels, bags of popcorn, lollipops, and bags of chips.

At the left of the graph is the label 'Number of Snacks Sold.' This means the graph will tell us how many chocolate bars, soft pretzels, bags of popcorn, lollipops, and bags of chips Chris sold.

Part Three: Scale , Scale a set of numbers along the left side of the graph , As here , 50 , 100 , 150 , 200
