How to create map with [x;y] coordinates? Mapping toolbox

I have a 416609x1 cell with [X;Y] coordinates in each cell. (or matrix 416609x2 with the same coordinates). I need to create map by these X:Y coordinates in eqaazim projection. And i have another 416609x1 matrix with values of each pair of [X;Y] coordinates. And the final result shold look like this picture

How can i do this?

I can only find ways how to do this with using a lat,long coordinates

No guaratees on the accuracy of the attached functions, but you may be able to convert between lat,lon and x,y using the attached functions for the Lambert Equal Area Azimuthal projection.
