This Web application is an interactive Line Chart implementation, using Javascript for the functionalities such as panning, zooming, re-centering, taking screenshot and so on. When the document first loads it makes an Ajax XMLHttpRequest to the Php script responsible to fetch the data (various values over a period of time). After fetching the data from the MySql database it parses them into a specific format usable by the Chart Object. Lastly, upon XMLHttpRequest success it populates the data in to the Line Chart. All of the above take place without the need to reload the page. Additional functionality is date filtering.

Excellent developer! He did everything I asked and went above and beyond. Anything he didn't know, he quickly researched and found a resolution immediately. Mr. Nikolaos was always available and had GREAT communication. Completely committed to finishing the task within the timeline. I'm upset I hadn't found him sooner but will definitely be using again going forward!

I had to outsource my project to an experienced professional who would take my project in a timely manner successfully. Among the many candidates who offered to undertake my project, I singled out the profile of Mr. Nikolaos, because he met the necessary qualifications and skills to complete it. I confess that he was excellent at his job and I will definitely hire him again. I highly recommend him to those who are looking for a passionate and hard-working individual who always meets deadlines.
