hi
can i build web page that contain graph or data from several devices?
This is relatively straightforward to achieve and has been discussed many times in the forum. It is a case of getting the URL to the graph image/s you want and putting them into a Custom HTML resource. The use of the Custom HTML resource/s allows you to pull different graphs and charts from all over Orion (or indeed any other web based app). Using iFrames allows you to pull in complete pages if so desired.
