Section 4: More 2d plot types Semilog A logarithmic axis is useful when data on one plot crosses multiple orders of magnitude (i.e. some large numbers, some small numbers). The following three commands create 2d plots (similar to the plot command), but with at least one axis on a logarithmic scale: semilogx-x-axis is logarithmic, y-axis is linear semilogy -y-axis is logarithmic, x-axis is linear loglog - both axes are logarithmic Type in the following commands into the Command Window. Then answer the questions load census 123 1 T II 10 HT load census adds which two variables to the Workspace? I Looking at the plot, in the year 1810, approximately what is the U.S. population?

Then answer the questions. What does the figure command accomplish? In the year 1810, approximately what is the U.S. population? Can you be more precise reading the semilog plot as compared to the linear plot? Why? Why is it advantageous to plot data with a large range of values on a logarithmic axis? Would it make sense to use a logarithmic x-axis for this example? Why or why not?
