I have a single figure/plot that contains multiple plots commands (not subplots - just multiple data sets). I need to be able to add the data to the current figure, see how it looks, and clear it if doesnt fit my visual criteria.
Any suggestions?
clf clears the entire figure. I just want to clear the last data set I added to the figure.

figure
hold on
h1 = plot(1:10,'r');
h2 = plot(2:11,'g');
if <your condition doesn't hold>
set(h2,'Visible','off')
end

If you're using this code you aren't deleting the plot. You are just making the plot invisible. The solution is to set visible to 'on' again if you want to show the plot.

Now if I were top do this inside a callback function i would do e.g.
h1 = plot(1:10,'r');
then how can I do the set(h2,'Visible','off') in a separate callback function?

In addition to the cyclist's answer, you can also do
delete(h2)
to actually delete the line, rather than just hide it. Also, if you didn't store the handles on plotting ( h1 = plot(...) ) you can find them after the fact using findobj
h = findobj('type','line')
finds a vector of handles to all line objects. You could then delete(h(1))

Hi Jiro,
Do you know how to undo one step after using the delete(gco)?
Thanks!

This seems a nice, principled answer. Don't like making them invisible because that takes up memory, def prefer to delete them!

Go to 'View' and click on the 'Plot Browser' to enable it. There you can check/uncheck the plots in the figure

You're welcome. And now the obligatory message: to help others who might have the same question, it would be great if you could vote for and/or accept answers that you think should be given prominence. Thanks. (I know there's only a couple of answers in this case, but it's good practice to let everyone know "answer X solved my problem")
