Correct Sprintf use on legend

Question

Jose 2012-9-20

Hi, I'm plotting 3 things. I want to make a box legend inside the plot but cant find the right way to do it, I want the third legend say:

CI = Ddata(1) +- 10%

The code is the next:

rango=10
legend('Original Data','CI=Ddata(1)',sprintf('CI = Ddata(1) \pm %.1e',rango),4);

It doesnt create the legend and give this on the Command Window:

Warning: Invalid escape sequence appears in format string. See help
sprintf for valid escape sequences.

Any help is appreciated.

Use:

\\pm % The first \ escapes the use of the escape \.

instead of:

\pm

Thanks, I focused on other parts of my code and forget about this.
