Clabel style in-line text for plot

I use 'clabel(C,h,v)' to add in-line text to the lines of the contour plot. Is there a way to do this for normal line plots? The example below shows what I mean, the orange line has 200 in-line, but the 900, 1200, 1400 & 1700 don't. Is there a way to do this for a normal line plot?
