Plotting data using Flot and MySQL
Install a httpd server
Install php
Write a php script to fetch the data from the database and render it
as a webpage.

This is fairly elaborate request, with relatively little details given.  More information will allow us to give better answers.
So I am trying to create a realtime plot of data that is being recorded to a SQL server.  The format is as follows:
Database: testDB
Table: sensors
First record contains 3 records.  The first column is an auto incremented ID starting at 1.  The second column is the time in epoch format.  The third column is my sensor data.  It is in the following format:
23432.32 112343.3 53454.322 34563.32 76653.44 000.000 333.2123
I am completely lost on how to complete this project.  I have read many pages showing examples dont really understand them.  They provide source code, but I am not sure where that code goes.  I installed httpd on my server and that is where I stand.  Does anyone know of a good how-to from beginning to end that I could follow?  Or could someone post a good step by step for me to follow?
Thanks for your help
