    PI VISION: XY plot & web API errors

    ydim

      Is there a limit on the number of discrete data points that can be plotted in a XY plot ?

      I'm trying to plot a couple of static reference curves, and bring in some live pi point data, which works without an issue until i reach about 30 attributes in the plot config. Any attributes added in after this are triggering error messages "PI WEB API Error: Index was outside the bounds of the array" and "XYPLOT Error: index was outside the bounds of the array"
      Thanks in advance,

          The restrictions on request data rate of PI Web API might affect the max number of data items that can be shown in PI Vision. The default is 1000. You can try increasing RateLimitMaxRequests parameter in the Configuration database to see if it helps. See the link below for more details.
