how to create customized curve ( only know the shape )

5 views (last 30 days)
Hi everyone~
I wanna turn couple curves (see pic above) into data in matlab. There are weird functions. All I have is the plots.
It's OK if I can just get some data that looks similar to those curves.
Is there a way to create such customized data? Any imaging processing tool to turn pictures of plots into data?
Let me know. Any thoughts are appreciated. Thanks~

Hi Proecsm!
Thanks for sharing! It worked pretty nicely!
Just curious about a further question: is there something that can automatically recognize the curve in the image? I think it's an image processing question - I'm not very familiar...
Let me know. Any discussion's appreciated~
