Of course. But you have to know what they are before you can intelligently decide to break them \1 Types of data \2 Categorical - ordered or not \2 Quantitative - continuous or discrete \1 Types of charts---he doesn't cover many in the book \2 Histogram / bar chart (\emph{The difference?}) \3 Order of bars needs to be systematic \3 Group bars sometimes \3 Sometimes stack bars to show breakdown \2 Box plot: Box is 25\%-75\% range, band is median, whiskers can be min/max, outer percentiles (in which case outliers are dots) \2 Scatter plot (can be combined with line graph) \2 Line graph \2 Area chart -  stacked' version of line graph - break down total into parts \2 Pie chart (ick) \2 Gantt chart - purpose is to show concurrent phases \3 Frisbee example: distribution, decompression, write \2 Network packet diagrams - eg. TCP, distributed systems \1 Scales \2 Zero-based \2 3/4 rule \2 When showing multiple related graphs, pick same scales if possible \2 Use breaks if you are going to make a jump in the axis \1 Non-linear scales \2 Log scale (base rarely matters, use what makes sense) \2 Transforms exponential into linear \2 log-log \2 Point out to the reader \2 Ticks can help show this \1 For next time  Robert Ricci committed Feb 05, 2015 71  \2 HW \#4 due on Friday, midnight  Robert Ricci committed Jan 30, 2014 72 73 74  \2 Moving into a mathier part of the book - next time is ratio games, Chapter 11 \2 Remember that the first paper assessments will be a lot of work  Robert Ricci committed Jan 30, 2014 75 76 77 78  \end{outline} \end{document}`
