Figure 3
The vertical axis of the stacked vertical bar graph ranges from 0 to 16 in increments of 2. The horizontal axis is labeled with the years “2011,” “2015,” “2019,” “2020,” “2021,” “2022,” “2023,” and “2024.” Each bar shows four colored stacks. A legend on the left identifies these stacks as: purple for “Q 4.0,” green for “S C 4.0,” orange for “S C Q M 4.0,” and blue for “S C Q M.” The data from the graph is as follows: 2011: S C Q M: 1; S C Q M 4.0: Not given; S C 4.0: Not given; Q 4.0: Not given. 2015: S C Q M: 1; S C Q M 4.0: Not given; S C 4.0: Not given; Q 4.0: Not given. 2019: S C Q M: 2; S C Q M 4.0: Not given; S C 4.0: 2; Q 4.0: Not given. 2020: S C Q M: 2; S C Q M 4.0: 1; S C 4.0: 4; Q 4.0: 1. 2021: S C Q M: 2; S C Q M 4.0: 1; S C 4.0: 1; Q 4.0: 1. 2022: S C Q M: 1; S C Q M 4.0: 1; S C 4.0: 5; Q 4.0: 2. 2023: S C Q M: 3; S C Q M 4.0: 3; S C 4.0: 6; Q 4.0: 3. 2024: S C Q M: 2; S C Q M 4.0: 2; S C 4.0: 6; Q 4.0: 4.
