Machine state visualization

A system comprising:

• at least one data processor;
• memory coupled to the at least one data processor, the memory storing instructions to cause the at least one data processor to perform operations comprising:
• receiving, from sensors coupled to a machine, state data characterizing a plurality of operating states of the machine during operation and monitoring data characterizing one or more operating parameters of the machine during a time period of operation;
• rendering, in a graphical user interface (GUI) display space, a graph comprising a plot of the state data and the monitoring data over time, wherein a first axis of the graph is indicative of the time period of operation and the plurality of operating states over the time period of operation and a second axis of the graph is indicative of the one or more operating parameters, wherein the GUI further comprises an interactive graphical object band spanning along an upper edge of the graph and comprising a plurality of interactive graphical objects arranged parallel to the first axis, along the second axis, wherein the plurality of interactive graphical objects correspond the plurality of operating states over the time period of operation;
• receiving data characterizing a user interaction with a first interactive graphical object of the plurality of interactive graphical objects within the interactive graphical object band, the first interactive graphical object being indicative of a first operating state of the machine over a first sub-period of the time period of operation, wherein the first interactive graphical object is bounded by a first edge indicative of a first time value of the first sub-period and a second edge indicative of a second time value of the first sub-period;
• and
• expanding the first interactive graphical object downward from the upper edge of the graph down to the first axis, responsive to the user interaction, thereby forming an expanded view of the first interactive graphical object, wherein the expanded view of the first interactive graphical object overlays a first portion of the plot extending from the first time value to the second time value, such that the monitoring data detected during the first sub-period between the first time value and the second time value is visible to the user through the expanded view of the first interactive graphical object.
