Flash/Flex: 1) Read data 2) Display line chart 3) Record click [repeat again]. That's all !

I have a set of files containing time series data with two columns: time and amplitude. I need a web based application which will display each of these files to the user, the user in turn will have the following controls: 1) Zoom in and out, 2) scroll left and right 3) Select a single data point As soon as the data point is selected the application will register the index of the data point on the server and proceed to display another time series (which was not displayed before) Implementation details: - Please check the attached simple schematic. - I want the project be implemented with Flex or Flash, so that it will run on any browser or mobile device. - The data storage could be done mysql with php, but it could also be something else - The time series data should be read from a mysql database as well. - You can use the build in LineChart function of Flex or an open source library like Axiis. - The project will run on my own server so I need the Flex and PHP source codes.
