Figure 10
The plot displays a scatter distribution of data points grouped into four classes with a legend titled “Class” identifying “Jamming”, “Abnormal Door Closing”, “Slowdown”, and “Normal”. The horizontal axis ranges from negative 10 to 15 in increments of 5 units, and the vertical axis ranges from negative 5 to 15 in increments of 5 units. The points form distinct clusters in different regions of the plot. The “Abnormal Door Closing” cluster is located on the left side around horizontal values near negative 12 and vertical values around 4 to 5, forming a compact group. The “Jamming” cluster appears on the lower right side around horizontal values near 12 to 14 and vertical values around negative 5 to negative 3. The “Slowdown” cluster is positioned in the upper middle-right region around horizontal values near 4 to 5 and vertical values around 8 to 10. The “Normal” cluster is located slightly above and to the right of the slowdown cluster, around horizontal values near 5 to 7 and vertical values around 11 to 14. The clusters are well separated with minimal overlap, indicating a clear distinction among the four classes. Note: All the numerical data values are approximated.UMPA visualization result.
