People a century ago, or at least Willis S. Jones and his associates, seemed to have an “interesting” habit of not including the legends and units in their charts and graphs. Usually, one might be able to guess the measurements based on the data points but if the title of the chart is also missing, well, might as well call the piece “something something numbers something.” Now that’s for charts and graphs, for maps, Jones and the gang probably thought giving each map a different orientation was funny: “Screw North arrow! Also, write the title 90° to the cross-section diagram then flip the values of the isolines just to confuse the hell out of folks in the future.” Lets’ take a moment to thank our other lord and savior, GIS.
