For example, a price change from $20 to $40 would be the same change on a log price scale as a price change from $40 to $80, as they both are doubling in price. Is a Log Scale More Accurate?

Learn how to choose the right scale for a graph based on the type of data, the purpose of the graph, and the audience you want to reach. See examples and tips.

When data is plotted as a chart, it can be done using two types of scales—arithmetic or semi-logarithmic. The difference in scale can completely alter the shape of the chart even though it is plotted ...

This post offers reasons for using logarithmic scales, also called log scales, on charts and graphs. It explains when logarithmic graphs with base 2 are preferred to logarithmic graphs with base 10.

Because logarithms relate geometric progressions to arithmetic progressions, examples are found throughout nature and art, such as the spacing of guitar frets, ... Logarithmic scales in science.

For example, the very long-term uptrend line in the Sensex is clearly visible in the semi-logarithmic chart (see Semi-logarithmic scale with trendline), not in the arithmetic chart. Similarly, the ...
