Helping adding Tittle to Plot (multititle)
显示 更早的评论
Hello,
I have a contour plot and i need a title like that for it:
"my title" variable1 variable2
My title is a character string always the same, but variable1 and variable2 change with every plot.
I have tried this:
title('my title', variable1, variable2);
But it did not work.
Error in ==> title at 55
set(h, 'String', string, pvpairs{:});
I also want to add units to the colourbar and a legend
Thank you very much!

If ‘variable1’ and ‘variable2’ are strings, this works:
variable1 = 'Velocity';
variable2 = 'Position';
figure(1)
scatter(rand(10,1), rand(10,1), 'bp')
title(sprintf('“My Title“ %s %s', variable1, variable2))

In that instance, just change the format descriptor to the version and precision of your choice:
title(sprintf('“My Title“ %.3f %.3f', variable1, variable2))
See the documentation for fprintf and its friends for a full list of available format descriptors.

When I use single numbers for both, it works the way it should:
variable1 = pi;
variable2 = exp(1);
figure(1)
scatter(rand(10,1), rand(10,1), 'bp')
title(sprintf('“My Title” %.3f %.3f', variable1, variable2))
Are ‘variable1’ and ‘variable2’ vectors? If so, you may have to subscript them in a loop:
for k1 = 1:2
figure(k1)
scatter(rand(10,1), rand(10,1), 'bp')
title(sprintf('“My Title” %.3f %.3f', variable1(k1), variable2(k1)))
end

I need to see your variables and the way they are stored. Something is strange about them.
Also, your new idea will run the numbers together. You have to add a string of a few blank spaces between the numbers to separate them:
title(['X 230mm ' num2str(important) ' ' num2str(Uinff)]);

title(['my title' var1 var2])
depending on the variable type, you may have to convert to string and add separators like whitespace when concatenating.
