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 ...

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.

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 ...

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 ...
