Logplot 8: A Powerful Tool for Creating and Editing Log Plots
Logplot 8 is a software program that allows users to create and edit log plots, which are graphical representations of data that use logarithmic scales. Log plots are useful for displaying data that span several orders of magnitude, such as geological data, sound levels, earthquake magnitudes, etc.
Logplot 8 has many features that make it easy and convenient to create professional-looking log plots, such as:
- A user-friendly interface that lets users drag and drop data files, customize plot settings, add annotations, symbols, legends, etc.
- A variety of plot types, such as linear-log, log-linear, log-log, polar-log, ternary-log, etc.
- A library of templates and symbols for common log plot applications, such as borehole logs, well logs, lithology logs, etc.
- A powerful data editor that lets users import, export, edit, filter, transform, and analyze data.
- A batch mode that lets users create multiple log plots from a single data file or a folder of data files.
- An export function that lets users save log plots as PDF, PNG, JPG, BMP, EMF, or SVG files.

Log plots are not only convenient for creating and editing log plots, but also for analyzing and interpreting data that follow certain patterns or relationships. One of the benefits of using log plots is that they can reveal power laws, which are mathematical expressions that relate two quantities by a constant exponent. For example, the equation y = ax b is a power law, where a and b are constants, and x and y are variables.
Power laws are common in many natural and social phenomena, such as the distribution of earthquake magnitudes, the frequency of words in a language, the size of cities, the popularity of websites, etc. Power laws imply that there is no characteristic scale or typical value for the data, and that small and large events are equally likely to occur. Power laws also imply that small changes in one variable can lead to large changes in another variable.
Log plots can help us identify and visualize power laws, because they transform multiplicative relationships into additive ones. That is, if we take the logarithm of both sides of a power law equation, we get log(y) = log(a) + b log(x), which is a linear equation. Therefore, if we plot log(y) versus log(x), we should see a straight line with slope b and intercept log(a). This makes it easier to estimate the parameters of the power law and to compare different data sets.
For example, Figure 4 shows a log plot of the frequency of words in the English language versus their rank. The data are from Zipf’s law, which states that the frequency of a word is inversely proportional to its rank. That is, f = c / r , where f is the frequency, r is the rank, and c is a constant. If we plot f versus r on a linear scale, we get a curve that drops quickly and becomes flat. However, if we plot log(f) versus log(r), we get a straight line with slope -1 and intercept log(c). This shows that Zipf’s law is a power law with exponent -1.
In summary, log plots are useful tools for creating and editing log plots, as well as for analyzing and interpreting data that follow power laws. Log plots can help us handle data that span several orders of magnitude, reveal patterns and relationships that are hidden on linear scales, and estimate parameters and compare data sets more easily.
