Many graph experts disagree with Darryl Huff’s argument that the scales of all graphs must begin at zero. I discuss why the rule for bar graphs may differ from that for line graphs.
Graphs that are not drawn to scale mislead the reader. This post shows another example of a graph where the visual representation of the numbers is not proportional to the numbers themselves.
The second finding, however, is the key weakness of a log chart: people have a hard time interpreting the scale. In the log chart, the final dot looks like it’s at around 60-70,000 deaths or so.
Presenting data - graphs, charts and diagrams Choosing the right scale on graph axes. Statistical information can be presented in diagrams, graphs and charts.
To address the problems of large-scale graph computing, researchers have conducted extensive fundamental research and key technology studies in recent years.
The data look very different when plotted on what is called a logarithmic scale. In a typical graph, values on the (vertical) y-axis are plotted linearly: 1, 2, 3, and so on, or 10, 20, 30, or the ...
