Require an algorithm to be built that can be incorporated into a website eventually. Algorithm will involve user being able to input a series of dates and a series of measurements which were taken on those dates. These inputs will then be graphed automatically (once enough measurements are input ie more than 3). A trend line will also be produced into the future predicting future measurements (based on previous measurements). Finally the algorithm will need to be able to automatically identify a particular point in the trend line and correlate that particular point with the calendar. For example...based upon the measurements input it is predicted that the measurement will be X on date X in the future.
