### 1.6.1.1 Options for log axes

1. Here, tick must be 1, 2, or 3. Annotations/ticks will then occur at powers of 10 times 1, 1-2-5, or 1,2,3,4,...,9, respectively.

2. Append l to tick. Then, log of the annotation is plotted at every integer log value.

3. Append p to tick. Then, annotations appear as 10 raised to log of the value (e.g., ).

Figure 1.7: Logarithmic projection axis using separate values for annotation, frame, and grid intervals. (top) Here, we have chosen to annotate the actual values. Interval = 1 means every whole power of 10, 2 means 1, 2, 5 times powers of 10, and 3 means every 0.1 times powers of 10. We used -R1/1000/0/1 -JX3l/0.4 -Ba1f2g3. (middle) Here, we have chosen to annotate log of the actual values, with -Ba1f2g3l. (bottom) We annotate every power of 10 using log of the actual values as exponents, with -Ba1f2g3p.
