1. Making line graphs How are line graphs the same as bar graphs? x- and y-axis Label axes Even spacing Title Use tickmarks

2. What is different from bar graphs? On x-axis, graph right at the tickmark Use dots and connect Line graphs are used for continuous data

3. Important and tricky for all graphs Have to determine the range of data so you can put tick marks and label correctly Use a “squiggly” if you aren’t starting at 0 Sample data % families Yearliving in poverty 198511.4 199010.7 199510.8 2000 8.7 2005 9.9 201011.7 Suppose there are 20 squares on the x-axis: how many should we skip? Suppose there are 35 spaces on the y-axis: what should we count by? How many should we skip? Should we use a squiggly?
