Analyzing Time Series Data on the Microsoft Surface
In our last demo we showed the simplicity of scrolling through pre-generated time series data on the Microsoft Surface. We have now implemented real data with the same functionality. The new software, seen below, demonstrates basic data visualization and manipulation of Buoy data collected throughout the Great Bay area. The graphing is created using Microsoft …
