zooming is handled by altering the xlim and ylim properties of the axes. So take the coordinate that you want to center, and subtract half the data width to display to get one edge and add half the data width to display to get the other edge, and xlim() and ylim() as appropriate.

See also https://www.mathworks.com/help/matlab/ref/matlab.graphics.interaction.internal.zoom.html but that does not permit you to choose the point.
