I don’t like using lengths with logarithmic scales. That is a second reason that I prefer dot plots over bar charts for these data. The previous example showed both responding to large values ...

This example uses a DATA step to generate data. The PROC PLOT step shows two plots of the same data -- one plot without a horizontal axis specification and one plot with a logarithmic scale specified ...

Rather, a linear price scale plots price level changes ... on the chart from left to right. A log price scale shows proportional changes in price. For example, a price change from $20 to $40 ...

Click on the graph axis you want to change to a logarithmic scale. Note that by clicking on different parts of the chart, you can select the whole chart, the plot area only, the legend or each axis.

In this example, Day 1 is the first day ... this is called a semi-log plot. A log-log plot would have both axis in an exponential scale. Then when should you use a semi-log plot and when should ...

But 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 like. By contrast, in a logarithmic plot, each ...
