I’m an observer on a project and am trying to view their progress by stages. When I view it on my computer, the chart is basically empty (no graphs), whereas when the colleagues opens the same chart on his computer, he can see all the graphs (horizontal bars). What am I doing wrong? Am I not allowed to see their progress, because I am only an observer and he is a project administrator? In which case, what non-editing project role should a supervising administrator have to be able to see the progress of teams under them? What settings should they use to make the graphs visible (rather than just the list of percentage figures on the left)?
