Right then, you better show your code (use the code tags).
Just to get an idea of your level of understanding;
Do you have some understanding and experience with in coding Arduino and web languages?
Describe your project in more detail;
List your hardware;
- What Arduino board are you using
- What ethernet chipset have you got
- What type of sensors are you using
Your software;
- Have you got a hosted site you can use
- At what stage is your program as it is now
I am still in the middle of developing and many more features are to come yet, also for trending which is at a very basic stage at present.
I can look at getting my code online somehow, there's a bundle of Arduino files as well as files for server and the client side.
Or I can post some relevant sections of the code in a new topic maybe?
For the graphing, go to http://www.highcharts.com/ and have a play around with their demos, this is what is used.
I hope you will have some patience 8)
