PHP File To Create Graph From mysql Data

My site keeps a record of which users are downloading a file at anyone time. In a database is stored the file id, the number of downloaders, the number of uploaders and the number of completed downloads. This data is updated every 4 hours for each file.

I require a cron script (php only please) which will create graph(s) showing this information. Graphs should be in .png format and should be of the form:

1 x pie chart (showing current sitution)

1 x bar chart (showing todays avergae situation AND yesterdays avergae situation)

1 x line graph (showing daily average situation from the last 7 days)

If all 3 graphs can be created in the same .png thats perfect, if not 3 seperate .pngs for each sql record is fine.

The graphs need to be generated throughout the day, updating the average/current info as necessary.

To calculate the averages and to display a history you will need to store a record of the data for each file as it is received every 4 hours. If you can use .dat files for this that is great. Otherwise storage in sql tables will be fine.

More information can be requested if necessary. Timeline is negotiable but if someone offers a reasonable bid and a swift completion time they will be accepted immediatly.
