Plotting data with large jumps in scale

Question about how to plot something. Say you have a data set, there's a bunch of data clustered between [1,3] then you have a huge jump and more data clustered at [68 70]. How do you plot so that the scale between 3 and 68 is small compared to the rest of the graph.

if true
  % And here is my code.
         figure
             hold on
                 L1=line( t(i:dF(3,1)), cumulativeDevelopment(1,i:dF(3,1)));
                 L2=line( t(dF(3,1):dF(3,2)), cumulativeDevelopment(2,dF(3,1):dF(3,2)));
                 L3=line( t(dF(3,2):dF(3,3)), cumulativeDevelopment(3,dF(3,2):dF(3,3)));
                 L4=line( t(dF(3,3):dF(3,4)), cumulativeDevelopment(4,dF(3,3):dF(3,4)));
             hold off
         set(L1                        , ...
             'LineStyle'       , '-'     , ...
             'Marker'          , 'none'   , ...
             'Color'           , [1 0 0]  );
         set(L2                        , ...
             'LineStyle'       , '--'     , ...
             'Marker'          , 'none'   , ...
             'Color'           , [0.5 0 0.6]  );
         set(L3                        , ...
             'LineStyle'       , '-.'     , ...
             'Marker'          , 'none'   , ...
             'Color'           , [0 0 1]  );
         set(L4                        , ...

             'Marker'          , 'none'   , ...
             'Color'           , [0 1 0]  );

I don't have your data or the function cumulativeDevelopment() so I can't run your code. I'm not sure what you're doing with line(). Why not use semilogy() to plot?

[Garrett Culos]

So I found a quick fix, not what i want though. If you look at the 'YTickLabel' near the end you can kinda see what im talking about. The semilog ill change the scale continuously, I want to change the scale so that a to b has scale y1, b to c has scale y2, and c to d has scale y1, where a,b,c,d are points on the y axis (1 3 68 70).

I still can't run your code but it's good that you got something that works (I think) for you.
