Boxplot with logarithmic y-axis

Question

1 个投票

I want to have a boxplot with logarithmic scale on the y-axis (similiar to the semilogy command for plot). I have not yet found a good solution. So far I transformed my data before creating the plot with the log() function, and afterwards I used the normal boxplot command. The plot itself looks nice then, but the y-axis is wrongly scaled. The y-range lies between -5 and -2, but I want to have exp(-5) to exp(-2). Is there a way to take the exponential of the whole axis? As a rather poor solution, I manually set the y-tick to [-5 -4 -3 -2] and then the yticklabel to {'exp(-5)',...,'exp(-2)'}, but this is for sure not an elegant solution.
