Hello to all!

I wonder if it is possible to mark (graphically) the intersection between two curves that are based on data, therefore, I dont have their equations. To be more precise I will ilustrate my example.

As you can see from the ilustration, there are supply and demand graphs for every season (they have the same color) and I just want to leave visible the supply graphs (or the graphs with the inverse s curve shape) and leave a mark where the demand was crossing.

Is there a way to do this? As I mentioned before, I dont have the equations but just the set of point that once plotted make the curves.

Thanks in advance!

I would recommend you to search on internet search engine or MATLAB File Exchange (FEX) you will defintely find answers to most of your problem!

All the best
