I have a legend in my pgfplots and want to manually position it at a point where the legend does not cover any text or measurement points.
I know the axis property
legend pos=north west, but it's not possible to position it at a custom location.
According to the documentation (link) only the following values are allowed:
/pgfplots/legend pos=south west|south east|north west|north east|outer north east
A style which provides shorthand access to some commonly used legend positions.
