Plot calculated data

Hi,

 

I have an processbook display that  taking data from PI and data from an external database. Based on time stamps of the external data, I extract the required data from PI.  I then do some checking on the integrity of the  PI data and then deterime the linear regression between the external data and the PI data. The calculations are too complex to use data sets. :-(

 

I want to display the  data points and the regression curve as some type of  graphic on the processbook display. I have tried to use  Excel and paste an image of the excel graph into the process book. It works but its a little clumsy nad awkward.

 

 

Any idea's . We don't have PI- ACE available at this time.

 

 

Kevin
