Stacked Bar Plot from Scientific Research

Statistical distribution of the contributions (%) of grain-for-green practices to vegetation restoration since 2000. The x-axis corresponds to the contributions in a. Ave.α is the integrated contributions of the grain-for-green practices. This value is calculated based on area-weighted statistics of the pixel-level contributions in a as follows: Ave.α = Σ [ α i ·area i ]/Σarea i , where α i is the vegetation restoration contribution of the practices in i -th pixel involved, and area i is the area of the i -th pixel. Noted that only regions with significant trends (passed the Mann-Kendall test at the 95% significance level) were considered in area-weighted statistics and rest were shown by the dotted box filled with gray.
