I have created a WCF service which is exposing SOAP as well as REST Endpoints and uses PI AF SDK programming to retrieve the latest archive value and timestamp of a PI Tag.
I have also created an ASP.NET website which consumes this WCF Service.
The website enables the user to enter a PI Tag Name and on click of a button, the website makes a call to the WCF Service and displays the latest archive value to the users.
I now plan to introduce a trend on this website which will display these archive values.
Can you please advise on what I could use to implement the trend functionality and how I can go about this?
Thanks in advance,
