Observation points show no error bars

Hi, I added some observation points to my FEFLOW model but unfortunately, no error bars are being depicted. Anyone has an idea how I can add error bars to my observation points?

All error bars have a RefValue and an Interval assigned which is in the same unit (m).

Any help would be much appreciated.

I am using FEFLOW 7.0.

Please assure you use either a dac-file or a fem-file with available computational results within the GUI. Please also assure, that you entered the confidence interval for the observation points. Otherwise you will not see the error bars.

The error bars which were evident in my model created in 7.0 do not show in 7.1?

Please try to select the spatial unit Observation Points and double-click on Hydraulic Head in the data panel to show the error bars. Logic behind: You plot the head onto the observation points to show data on these spatial units.
