Figure 7
In panel (a) on the left, the horizontal axis is labeled “coverage” and ranges from 0.0 to 1.2 in increments of 0.2, while the vertical axis is labeled “density” and ranges from 0.0 to 1.2 in increments of 0.2. A series of colored points forms a curved, step-like pattern. On the left, points cluster near coverage values from 0.2 to 0.4 with density close to 1.0 (yellow tones). Moving right, the points gradually shift to coverage between about 0.4 and 0.8 with slightly decreasing density around 0.98 to 0.96 (green to teal tones). Near coverage values close to 0.9 to 1.0, the points form a vertical drop, where density decreases from around 0.95 down to about 0.75 (dark blue to purple tones). A color bar on the right labeled “number of restricted dimensions” ranges from 0 to 5, corresponding to the color gradient of the points. A red square highlights a point near coverage 0.95 and density 0.93. In panel (b) on the right, a rectangular shaded region is shown with a horizontal blue line across the middle labeled “0.02” on the right. A small blue value “0.0053” appears near the upper center of the shaded area. On the left side, a label reads “S superscript C (5.6 e minus 46) 1.9 e minus 06”. In the top-right corner, a boxed legend displays two metrics: “Coverage 0.943” and “Density 0.93”. The background consists of light gray layered rectangles, suggesting regions or thresholds. Note: All numerical data values are approximated.Scenario discovery results for low on-time maintenance completion: (a) Density–coverage trade-off, and (b) Corresponding scenario box
