When analysing bar charts and trend graphs it is good practice to describe what the graph is measuring. If there is no title you should give a description of what the two axes (i.e. the horizontal line and the vertical line) are representing.
The bar graph below shows the results of a survey in which a number of dogs were asked "What is your favorite food?" No dog gave multiple answers. What percent of dogs said that their favorite food was cats? A. 6% B. 17% C. 11% D. 30% . EXAMPLE 3.1.1 SOLUTION. First, we find the number of dogs who responded to the survey.

Graphs of parameter estimates can be thought of as proto-multilevel models in that the graph suggests a relation between the y-axis (the parameter estimates being displayed) and the x-axis (often time, or some other index of the different data subsets being fit by a model).
A bar graph is made up of bars - columns - plotted on a chart. Here is how to read a bar graph. The bars represent discrete data. The height of each bar indicates the value of that bar as defined by the y-axis Axis Label.
