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.

I am extremely happy with the service provided by FreeAL. I have used loads of programmers in the past. Many were unable to do what I needed. This guy is probably the best programmer I have encountered. I have waded through so many empty promises in the past. I finally found someone who can do the job. This is YOUR guy if you need something fixed that is related to PHP. I would strongly recommend using FreeAl. Very talented, reliable and helpful person. Excellent communication and knows what he is doing. I will be glad to work with him in the future again. Thank you for your help.

    Thank you for taking the attention. After reading the following, you'll understand why it is necessary to choose my own Developer Studio. My Developer Studio for 7 years now engaged in a highly loaded with projects for the LAMP technology, various frameworks like Zend, Yii, and also Python and RoR. We are developing a database, and create projects of high complexity with cached data that are working on a system of simultaneous requests the order of 100 000 and more. Not olny DBMS like mySQL, but also noSQL data storages like Mongo and etc. As we optimize the work of established database systems under the new conditions, we can write queries in such a way to ease the load on the server.
