How can you get ggplot2 to display an inset figure when the main one has a log scale?
ggplot2, graph, insets, r
Solution
With a log scale, simply use the exponent rather than the absolute value to specify coordinates. So, in this example, use 0 < x < 1 since the scale runs from 1e0 to 1e1:
p = qplot(1:10, 1:10, log='x')
g = ggplotGrob(qplot(1, 1))
p + annotation_custom(grob = g, xmin = 0.3, xmax = 0.9, ymin = 6, ymax = 10)
Problem
I have a figure with a log scale on the x-axis. Trying to create an inset figure doesn't work, but seems fine if the scale is changed to linear. Is there a way around this, or is it a limitation of ggplot? This works: ``` p = qplot(1:10, 1:10) g = ggplotGrob(qplot(1, 1)) p + annotation_custom(grob = g, xmin = 3, xmax = 6, ymin = 6, ymax = 10) ``` This doesn't: ``` p = qplot(1:10, 1:10, log='x') g = ggplotGrob(qplot(1, 1)) p + annotation_custom(grob = g, xmin = 3, xmax = 6, ymin = 6, ymax = 10) ```
