A demonstration using CSS canvas to draw data charts. The data is stored in an XML database and retrieved via AJAX. I use PHP to add and retrieve data from the database.

Stock Quote system

There are three features for the Stock Quote system. All three features are linked to each other.

View Quotes (stock_quotes.html) - View and analyze stock quotes from the database. An HTML form sends Javascript AJAX requests to retrieve and parse XML.

Update Symbols (update_symbols.html) - Adds new companies to the database. An HTML form sends form values via AJAX to a PHP script that creates a new XML file to store the new company. This XML will also be used to store stock quote data for that company.

Add Quotes (add_quotes.html) - Adds a quote to a company existing in the database. Quote times are saved as current UTC time. An HTML form sends form values via AJAX to a PHP script. The PHP script searches for the company entered and stores the data into the XML file.
