There are NO data explaining the multiple '40's and the single '30' labels.I
have tried several versions of commands like   [cs,h]=
contour(xi,yi,zi,IsoStep); clabel(cs,h,20:5:60,'fontsize',
13,'LabelSpacing',1500); (IsoStep is different number-series like
'20;30;40;50;60'   or  20:10:60   or  20;30;50;60 or .....note: The matlab
version clabel(c)  seems not to be implemented in Octave. Would give just
one label for each contour...Just now I use the fail plot, copy to a drawing
program and hide the 'fail labels'.. not smart...

Does 

demo clabel

work for you?

Can you make the data public so that we can test with your data and program?
