Hi matlab user,
Let i have ,x=[1 3 5 7 9]; y=y=[1 4 6 8 12];
scatter(x,y,'*');
r=corr(x.',y.','type','pearson');
A=r;
[rho]=corr(x.',y.','spearman');
B=rho;
formatspace='Pearson correlation coefficient r = %d';
str=sprintf(formatspace,A);
annotation('textbox',[.3 .5 .1 .1],'string',str)
In the text box i want to get the text for spearman correlation coefficient too. if any one know then kindly help me.
This question would be clearer if you can provide an example of the plot you are trying to make. But in any case, it sounds like you can just add a text box or annotation to the plot.
@Stephen Politzer-Ahles, Please check my edited question, if some information is missing then let me know. thanks
Like I mentioned above, this would be easy to do by adding a text box (annotation). What you're trying to add is not actually a legend.
Dear matlab users, please check my edited question, if possible then kindly suggest me the solution.thanks
You can put multiple lines of text into a text box by passing the strings as a cell array using { }. Lots of examples of this kind of thing can be found online, e.g.
>> plot(1:5,1:5)
>> annotation( 'textbox', [.2 .7 .15 .1], 'string', {'example' 'example2'} )
It is also easy to add text boxes by hand using the plot GUI.
@Stephen Politzer-Ahles, sir now i got the point of putting multiple lines of text into a text box. In my question,now the problem is how to pass the second text (spearman correlation coefficient rho = %d) to the variable name formatspace. Also i have used %d, which gives me result like (r=9.9124e^-01), how i can get my result like r=0.99124. thanks
As I showed in my example, if you want the text to appear on two lines it has to be as two separate strings. As for how to change the way the number is formatted, see the help pages: https://www.mathworks.com/help/matlab/ref/sprintf.html
@Stephen Politzer-Ahles , Sorry sir, I can't convey my question in a good way because my English writing is not good.
After the operation of my code in the question, i get only
(Pearson correlation coefficient r = ), if possible then please add some function to my code so that i can get the text for both the pearson and spearman correlation coefficient. I am waiting for your reply. thanks.
Sir Stephen, i am still waiting for your your reply because i can't find any solution for my problem. thanks
>> formatspace='Pearson correlation coefficient r = %.2f';
>> str=sprintf(formatspace,A);
This is all explained in https://www.mathworks.com/help/matlab/ref/sprintf.html#input_argument_formatSpec.
