could anyone tell me how to have equal spacing of selected numbers with respect to axis with respect to the command line
set(gca, 'XTick', [0, 1, 2, 23,24]);
I want to have equal spacing between 0,1,2,23 and 24 with respect to x axis.

The data you are plotting, are the x values for it only 0, 1, 2, 23 and 24, and nothing else?
Is it necessary that the data cursor should show the 24 when it is over information in that range, or is it okay if the data cursor can be wrong?
... And you are still using R2015b, right?

tx = XData;
mask = tx > 2.5;
tx(mask) = tx(mask) - 20;
plot(tx, YData);
xlim([0 4]);
set(gca, 'XTick', [0, 1, 2, 3,4]);
set(gca,'XTickLabel',num2str([0;1;2;23;24]))
dcm = datacursormode(gcf, 'DisplayStyle', 'datatip', 'UpdateFcn', @myupdatefcn, 'SnapToDataVertex', 'on');
with
function txt = myupdatefcn(src, event)
loc = event.Position;
x = loc(1);
y = loc(2);
if x > 2.5; x = x + 20; end
txt = {sprintf('x: %g', x), sprintf('y: %g', y)};
The assignment to dcm and the function are not needed if you do not care about what data cursor mode (tooltips) shows.

Make it easy for us to see by using the green and brown frame icon to insert a picture/screenshot. Or else attach a PNG image instead of a .fig file, which takes multiple additional steps to see.

You can compress data between 2 and 23 ticks roughly by
%before plotting
XData(XData>2&XData<23)=(XData(XData>2&XData<23)-2)/(23-2)+2;
XData(XData>=23)=XData(XData>=23)-(23-2)+1;
%plotting code
plot(XData,YData)
%renaming of ticks
set(gca, 'XTick', [0, 1, 2, 3,4]);
set(gca,'XTickLabel',num2str([0;1;2;23;24]))

Also you can use command
xlim([0,24])
to strech axis.

Try this to find File Exchange submissions that allow a "break" in the axes: https://www.mathworks.com/matlabcentral/fileexchange/?utf8=%E2%9C%93&term=broken+axis
