I have a grid of plots (see example below) with different x axes but all the same y-axis. What is the best way to label the y-axis without being redundant? The information is in the legend, but this is not a solution.
Here are two options I am considering:
- center one label on the right hand side in the same font as the x-axis labels. This could make it ambiguous if the y-axis label is associated with only one subplot.
- leave the y-axis empty and provide information in a figure title (response of 'y-axis label (units)' to 15 variables).
This plot will be published in a scientific journal. Low resolution is intentional for this post since it is unpubliished. Any other suggestions appreciated.
