Multivariate Time Series Annotator

Overview

The goal of this project is to develop an executable non-web application tool that allows the algorithms team at Tandem Diabetes Care to visualize and annotate data related to insulin infusion therapy. The algorithms team at Tandem Diabetes Care needs a tool that can help them visualize and annotate large amounts of data generated by the wearable insulin pumps. It is important to note that this tool can be used by anyone who is in need of a data visualization tool, but was made to meet the needs of the algorithm engineers at Tandem.

The Multivariate Time Series Annotator tool features a user-friendly interface that enables users to upload and visualize data in a CSV or HDF5 format. The tool was developed using Java as the main goal was to develop a tool that is able to handle large amounts of data while remaining responsive. It was developed by using the JFreeChart framework. Users are able to add up to 6 resizable charts, each which can have an unlimited amount of series. This tool is able to visualize data in a line chart, step chart and scatter plot. It also allows users to annotate the data with shapes and/or text comments, providing better context for the data. Users are able to sync multiple charts. It also allows users to export their annotations in a CSV format which is easy to understand as well as being able to import those annotations back into the application.
