change font size of subplot text

i have a subplot with text labels next to plotted data...i use set(text,'FontSize',8) intending to change default 10 size...text is a handle/struct with such a property and i don't get any errors but there's no effect at all:

for k=1:8:(length(datalabel))  
text(l_i(q)+5,var_i(q)-1,datalabel(k:k+7))
set(text,'FontSize',8)
q=q+1;
end

Please do not use text as the name of a variable: it is the name of the routine to draw text on a graph.

Ok Walter...any ideas ?

I use the following code, it can work

clear;clc;close all
subplot(335);
fplot(@sin,[-1,1]);
tx = text(.5,.5,'y = sin(x)');
tx.FontSize = 20;

I don't know what's happening! it won't work for me!...it's works totally indifferent of the setting...i mean i get the text but it doesn't change size! i'm using matlab R2011a..is it ok?

I am using matlab R2016a. I think because you use a text as a parameter. The text was interpreted as a command and make a new text. set command works on that new text not on original text.
