MATLAB: Rearrange halves of yaxis in graph

axesgraphindexingMATLAB

Hello,
I need to rearrange my graph. I would like to rearrange the y axis so that, y for x=1.25 to 2.1 will be placed before the y values of x = 0 to 1.25. But there shouldn't be any change in the xaxis. I don't think I can use 'fliplr' for this. But I am not able to figure out the code to do this through indexing.
Pls help me.

If I understand correctly, move the section of data from x=1.25 to x=2.1 and place that segment just before x=0.
Assuming you have two variables x & y that were used to plot your data: plot(x,y), 
segmentStart = 1.25; 
segmentStop = 2.1; 
placeBefore = 0; 
newIdx = [...
    find(x<min(placeBefore, segmentStart)), ...   %index values prior to insertion point 
    find(x>=segmentStart & x<=segmentStop), ...   %index values of segment to be moved
    find(x>=0 & x<segmentStart), ...              %index values of section between insertion point and start of segement
    find(x>segmentStop),...                       %indes values following the segment
    ];
plot(x, y(newIdx))
