Reading scaled picture and bar graphs

Reading a scaled graph means using the axis scale. Histograms also need their scale to read frequencies.

Reading values on a scaled graph extends to reading what the shape of a graph says about a story.

Reading a scaled bar graph means reading the scale on the axis, as a scatterplot uses a scale on each axis to place points.

Reading the top of a thermometer's liquid and reading the top of a bar both mean finding what one gridline is worth and counting up from a labeled line.

A table of counts and a dot plot are two ways to show how often each value occurs; each count in a table is a stack of dots, and each dot is one value in the original list.

A scale on the axis tells how much each step stands for; plotting a point in the first quadrant needs the same scale on both axes.
