Event Timeline

Use Cases

The Event Timeline shows the sequence and duration of events over time. This tool is most helpful early in the exploratory process to identify patterns that you want to investigate in more detail. This is a good tool to lead to Descriptive Statistics or Time-Series Correlation.

Specifications

The Event Timeline is a univariate analysis that you can perform on the Downtime model, the Defect model, or a categorical field on the Cycle model. You can select multiple machines of a given type.

Analysis

The Event Timeline is an exploratory tool that shows events over time, split by a category. If you select the Downtime or Defect model, the events are split by Reason. If you select the Cycle model, the events are split by a categorical field that you selected. The analysis plots a trace from the beginning to the end of each individual event, with time on the X axis and category values on the Y axis. Note that the Sight Machine platform treats defects as instantaneous events; defects are marked with a single timestamp. In addition, consecutive cycles are collapsed into one event. For example, on a machine with 1-minute cycles, ten consecutive cycles with the same category are shown as one 10-minute block instead of ten 1-minute blocks.
