Hi there, I have two bar chart figures I want to annotate to show significance, however, I’m unsure how to this correctly.
Figure 1 displays the visits counts (y-axis) of different species (x-axis) at different food types (legend). A chi-square test of association was used to determine the food preferences (food type) and different species.
Figure 2 displays the mean proportion of time vigilant (y-axis) of different species (x-axis). An independent samples kruskal wallis test was used, followed by a pairwise comparison, to determine significance differences in proportion of time vigilance between species.
I’m guessing ’*’ above columns show that they are significant. So would this be more appropriate in figure 1? Using letters, I’m guessing, would be more appropriate for figure 2. as it shows what groups are significantly different from one another. However, should I also use ‘*‘ in figure 2? Additionally, is it appropriate to use different forms of annotation between figures or does the format need to be consistent across figures?

There is nothing wrong in using different annotations nor there are certain guidelines for doing so. Hence you can use whatever way you find appropriate provided you give a footnote for those annotations indicating what they exactly stand for.
You can use any of the signs provided you define their meaning under the legend.
