Hello,
When I create graphs like "Portfolio Value" or "Portfolio Gain" for portfolios containing assets based in different currencies the cursor shows the correct protfolio total but the actual blue graph does not. When I switch off under "View" the option "Exchange rate adjusted" the cursor and the graph show the same amounts, however the totals are now meaningless as they are not exchange rate adjusted. When the (sub)portfolio contains assets which are all based in the same currency (no matter which) all works fine.
I run FundManager Professional 2020.16.4.100 but have observed this inaccuracy for some time, also in prior versions.
