show just one curve

Hi. Im using GUIDE to create axes component that I then plot raw data to. I want to also see a smoothing function superimposed. I use csaps(x,y,p) where p is the smoothing parameter.

Here is my code that plots several smoothing curves at once

axes(handles.axes1);
fnplt(csaps(x1,y1,1),1,'k--')
fnplt(csaps(x1,y1,0.8),1,'r:')
fnplt(csaps(x1,y1,0.6),1,'m:')

How can I plot the smoothing curves just one at a time with only one showing.

Perhaps I do not understand the question: If you want to see one line only, comment out the two other fnplot line?!

I want the ability to try different amount sof smoothing and then use this one. As my data is always different, I wont know before I try

Use

cla

to clear the old stuff and replot only what you want.

But this will also remove my original x,y data. Can I somehow use tags to plot the fnplts and then delete a particular tag?

[Sean de Wolski]

You couldn't just replot x/y?

Yes this seems the way I will have to do it, but its not very elegant.
