Old data in graph using web sever

[Eric Marquardt]

I'm using the web sever to remotely monitor and control my application. Using the .snap or .monitor works fine and displays my front panel just like it should. When I request control, I get it and the front panel works fine but the data in my graphs is old. The time axis is correct but the data is old. It doesn't seem to be using updating the graph data.

Eric,

How old is your data? Is it off by a second or two or minutes? How fast is your VI running? How much graph data is being sent with every update? Are you graphing more than one channel? How are you plotting your data? Are you setting any axis properties on the graph (time and date for t0?)?

Most of these questions come from statements made in the LabVIEW User's manual on Remote Panel (Chapter 17). It states that you should be cautious about the amount of data that you send via Remote Panel. Please let me know. Thank you.
