In the image plotted in the figure, select with the mouse to enlarge / reduce,
If anyone knows how to zoom in / out at any multiple around a given coordinate, would you please let me know?
I want to change the attached before image to a figure like the after image.

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.
