Project Description


Our system keep monitor and keep an history of temperature at a certain date. We want to access the last 24 hours temperature on internet. Each client has a MySQL database. Each database contains several table (represent the temperature sensor). A table has the following structure: Date (of the form 2013-03-10 13:00:45) | Temperature (a double).

Specifications are the following:

- Each chart may contains one or more (up to ten) lines (represent temperature) with different colors.

- The page may contains multiples graphs.

- x axes: Last 24 hours with an interval between each unit of 3 hours

y axes: Temperature

- Chart need to be in Javascript

- Tool Tips must be available (when the mouse is placed on a point we have the following information: Date: Temperature)

- Auto refreshing graph

- The result must be, of course, compatible with our database

- Possibility of hiding lines by clicking on icon

We have already done a first version (screen shot available) but it contains only one line. So it is possible to reuse it, if you want.
