Help : Php Frequency Polygon How to use php ad mysql to make a frequency Polygon

[electron 0]

I want to create a frequency polygon in php using the image feature(GD library)

The data consists of 2 colums: Time (in timestamp format) and Frequency(eg sales, price, profits, etc) of Data.

Time is to be ploted on the X- axis and Frequency is to be plotted on the Y-axis.

The time range can be in hours, days, weeks, months, years, or can be a specified range .eg. frequency of data from 9:00 am to 12m or from 1/1/2005 - 1/7/2006.

So accordingly the script should adjust time on the X-axis. Note the user should only specify from the start time to the end time which could be days ,months, yrs etc

The data would be stores in MYSQL DB .

Pls tell me how to do it or are there readily available scripts suitable to my requirements.
