# IDMVis: Temporal Event Sequence Visualization for Type 1 Diabetes Treatment Decision Support
Zhang et al. introduce IDMVis , an interactive visualization tool for visualizing type 1 diabetes data for a single patient. IDMVis includes a novel technique for folding and aligning data and scaling the intermediate timeline.
The authors design IDMVis based on a qualitative evaluation carried out with six domain experts in diabetes care.
Figure 1 shows an overview of IDMVis. Section A shows a 14-day overview of the patient's glucose level. In the trend lines, green indicates a normal glucose level, purple indicates a high glucose level and orange indicates a low glucose level. Each blue triangle represents an event logged in the patient's logbook. Section B shows a detail panel for the selected day. Section C shows the distribution of insulin and carbohydrate intake for the selected event.
Figure 2 shows the single-event alignment feature, it allows the user to specify an event and align the trend lines accordingly. Figure 3 shows the dual-event alignment feature, which aligns the tread lines between two selected events.
The authors build IDMVis on top of exisiting EHR visualization systems from the survey by Rind et al.  and a book chapter by Rind et al. . Temporal folding of events is inspired by LifeLine2  and CareCruiser.
