area of intersection between two curves

I have 2 linear curves plotted in one graph with a single x axis. I want to calculate the area of intersection between the two curves. Is it possible to do that in dplot.

No. $AREA(n) gives you the area formed by closing curve #n, but there's no mechanism for finding the area enclosed by intersections of 2 (or more) curves. Good suggestion, though, thanks.

Thanks for your support.
If it is not possible to get the intersection of two curves directly, can you provide a function to calculate the area under a curve from one point to the other, say a function like $AREA(n,x1,x2). In that case we can find the intersection points (x1 and x2) manually and calculate the intersection area by subtracting the areas of two curves between x1 and x2.

Can you please let me know how much time it will take to incorporate this function. In how much time, can you provide me a patch over the current version if I buy the license today. This requirment is urgent for me.

No, sorry. I don't work that way. It's on my list (along with a lot of other things).
