Stacked Bar Plot from Scientific Research

Annual grain yield. The dashed lines are the baseline values of the WM rotation, and the error bars are the standard deviation of annual value summed over winter wheat and summer maize. One-way ANOVA with two-sided and post-hoc test was conducted to determine significant differences. Different lowercase letters denote significant differences between the rotations at P < 0.05. The exact P values: P = 0.001. n = 18.
