Dear sir i  want the contour values  automatically display on the contour.

Hear is the code and sample contour plot. 

labelledcontourplot(x^3-y^2,x=-3..3,y=-3..2,axes=boxed);

Thanks a lot for your suggestions

Thanks a lot for your suggestions

thanks but still i can not get the data

restart;
with(ExcelTools);
                              [Export, Import]
g:=y*(1-1/(x^2+y^2)):
# g = 0.1
plots:-contourplot(g,x=-1..1,y=0..2,contours=[0.1]); p:=%:
dt:=plottools:getdata(p):
L:=ListTools:-Flatten(select(type,[dt],Matrix)):
M:=<op(L)>;
#plot(M);
#M[1..10,..];
#Lots of repeats, so:
Mu:=Matrix(ListTools:-MakeUnique(convert(M,listlist)));
#plot(Mu);
