# This graph about logarithmic and arithmetic plots. Shoudn't it be the other way around?

From the textbook 'Brock biology of microorganisms, 15th edition'

The black lines points to the linear graph with the caption 'Logarithmic' and to the curved graph with the caption 'Arithmetic'. Isn't this the reversal of what they are?

• No it's correct. The arithmetic plot uses the left side of the graph and if you take the log of the values on the arithmetic plot (log10) it'll plot out a straight line; the red one which use the right side as the y-axis. Jun 13, 2021 at 8:11
• To add to @m4rio's comment: As someone once said "biochemists worship at the alter of the straight line" (It is the logarithmic plot that is linear, as is the Lineweaver-Burk plot, the Eadie-Hofstee plot, the Hanes plot, and quite a few others: they are all linear transformations of non-linear 'primary' plots) Jun 13, 2021 at 9:19
• It's always a good idea to carefully examine the numbers on the axes and draw your own conclusions before looking at the labels. Jun 13, 2021 at 13:28
