Error Retrieving DVR Data

If you are you getting an error when trying to use the Playback feature. It means you most likely have enums and/or strings points in your equipment(s) that are being used in your graphic. To resolve this issue, you have to add a hisInterpolate:cov tag to the enums and/or string points. This is required because they are seen as multi-state values and being treated as numbers, which means linear interpolation. We need to override this default behavior, which you do by adding hisInterpolate:cov tag.
