-The bars in the graph above show predicted population changes for each basin country combination.
+The grey bars in the above figure show predicted population changes for each basin country combination.
 The background shading follows a gradient from Near Threatened ("-0.2" is 20% loss) to 
 Critically Endangered ("-0.8" is 80% loss). 
 The width of the bars is proportional to the river length on a log scale.
