In full
A bar chart shows amounts by the heights of its bars: the things are along the bottom and the amounts up the side. First see what one square stands for on the side: the gap between neighbouring numbers (1, 2, 5 or 10). The number level with the top of a bar is that thing's amount; a top halfway between two lines is halfway between their numbers. Or count how many squares tall the bar is and multiply by what a square stands for. The tallest bar is the most and the shortest the least; take away for how many more, add for how many altogether.
