How do I create a string for a plot title from one fixed string and one I get from INPUT?

4 vues (au cours des 30 derniers jours)
I have a problem in plot's titles. I do the following:
name = input('plot''s title');
set(gcf,'NumberTitle','off');
set(gcf,'Name',name);
This is perfectly OK and it gives the name that is already input as a title, but I want to have a title in which one part is always fix and the other part is the name that I can change it each time. For example I would like to have titles like this:
name1_name2
name1_name3
name1_name4

name1 = input('Plot's title part 1','s');
name2 = input('Plot's title part 2','s');
t = 0:0.01:10;
y = sin(t);
plot(t,y)
title([name1 '_' name2],'Interpreter', 'none')
set(gcf,'Name',[name1 '_' name2]);
HTH,

Thanks a lot Arnaud; this is what I want. One thins that I didn't understand is the 6th line (title([name1 '_' name2],'Interpreter', 'none')). What does it do? Cause even if it is removed the program still works appropriately!

set(gca,'Name',...) sets the name of the figure window, not the title of the plot. title(...) puts a title on the actual plot. The 'Interpreter' property is for the TeX intepreter so that it doesn't think the '_' means a subscript. Have a look at the doc for title:

In addition to what Arnaud suggests, I also sometimes find it useful to keep a bit of name in the plot and change only the second bit when you update it. For example, use
set(gcf, 'Name', ['My Application: My Document']);
to set the title initially, then update the 'document name' (or whatever) using something like this:
name = get(gcf, 'Name');
set(gcf, 'Name', [name(1:find(name == ':')+1) 'My New Document']);
