项目描述

Develop an android app with the following different objectives: 1/ drawing an exponential curve and extrapolation data based on the user entering data points (min 2 max 10) as x = date and Y = value. Data will be entered over time by user (need to store data and graph to be adapted as data are entered). Initial y values are generally basal(<1) and curve should be calculated on positive y values (over 1). 2/ Comparison of the calculated curve versus a given reference curve always drawn. 2 curves centered on the inflexion point (switch from basal <1 to over 2). Choice of color for the calculated curve. Standard one always red. 3/ If possible comparison of the slope (or R2?) of unknown curve versus reference curve with the question are the 2 curves similar or not. 4/ Based on the unknown curve, predict the day when y value will be equal to an user decided value (i.e. 25). For the graph X scale from -5 to +10, Y scale from [url removed, login to view] to 30. Data and curves stored.
