To clarify, are you saying if you switch off diagrams for the layer you still do not see the points in the conical projection? Can you share your layer/project?

I was trying to reproduce that bug today in both versions (2.6.1 and 2.8.1) and by chance understood that these are two different bugs but they are not connected with conic projection.

1 bug - wrong appearance of diagramms (instead of one diagramm for 1 city there were only 2 or 4 diagramms for the more than 200 cities) - is only in old version of QGIS, it works good in 2.8.1. So it is solved.

But the 2 bug - when I was working with one shapefile (with cities and diagramms) and after that do some changes in another shapefile (called States), diagramms in Cities shapefile disappear. I randomly found that they appear again only when I go back to the shapefile with diagramms and click ATTRIBUTES -> Included in diagramms (and choosen attributes are getting highlighted). If you don`t do this trick, you can't see the diagramms on the map again, even if you have already selected the attributes in table 'Included in diagramms'. So I think it`s not very obvious for user and probably should be solved.

Hope, I`ve explained it clearly (unfortunately I have QGIS in my native language and I don`t know the exact name of these options).

I also wanted to note that I didn`t switch off the diagramms.

It sounds like you're describing something which is related to a fix I made after 2.8.1 was released. Can you test with a development snapshot and let me know if this had been resolved?

I should appologize for wasting your time since I finally after several days of random clicking found the reason of that "bug":
I just needed to click 'Refresh' on the tools pannel to see my diagramms again after changes in other layers. I didn't pay attention to that button (since I probably have never used it before) so when I did some changes in another layers diagramms disappered. When I clicked on 'Refresh', they appeared again.

So I guess the solution of the problem is found but maybe it`s usefull to make the process more obvious that some people would not get into stuck like me.

PS Did you mean I need to download some 'QGIS night build' and test the problem again?

Yes please, I'm 99% sure this is fixed now

I tried last night build of QGIS (2.9.0) and now it works ok! Thank you!
