2 questions regarding text() function in a FOR loop for a CURRENT graph.How to define CURRENT graph?

Hi guys I have big difficulty adding text to a figure in a FOR LOOP in my function. when the execution of my function is finished;figure (100) is opened, and i use the same below FOR LOOP and it works out and prints out numbers (variable k) in those specific locations.but when I add the same FOR loop in my function, it doesn't print out any thing. Any help would be really appreciated. here is my function:

 function [ ]=par1()

 figure(100);

 plot([2;3;4],[1;0;5]); // the first graph

 hold on

 plot([0;1;3],[6;4;7],'Color','c');  //the second graph

   for k=1:+1:10

    figure(100); 

    text(k,0.5,num2str(k)); 

    drawnow;

   end       //end of for Loop

end       //end of Function

I tried replacing line 7 (figure(100)) outside the For loop , but it didn't work out then I removed line 9, but it doesn't change anything either.

My other question is in the same regard. I wanted to change the XTickLabel of figure(100) to other values in my same function.So i added this line after line 10 (end of for Loop)

set(gca,'XTickLabel',[0:+60:240])

it doesn't work. but if i run these lines after executing my function, it works perfectly fine(meaning the k values appear in my figure). so it seems to me that in both problems, I don't correctly state to the program which figure is the CURRENT one or which AXE is the current Axe. but How can i tell it to my function.

Please format your code properly. You can look at some other threads to learn more details. Leading line numbers are a bad idea, because we cannot run your code using copy&paste anymore.

I do not understand, what exactly happens, e.g. where the text appears and where it should appear. TEXT appears in the current AXES, so perhaps you want to set this instead of the current FIGURE.

Thanks Jan, I added the line numbers that if someone wants to refer to a line, he/she can do it easily. The text does not appear at all, if i leave the for loop in the function. if i execute the function without the FOR loop and then after i run the FOR loop,it works fine. the same thing for the set() command. if i leave it in my function, it would not change the AXE, but when i remove it from my function and run it externally (through command line) after finishing executing my function, it works fine.

Did you use the debugger already and set a breakpoint inside the FOR loop? Are there problems with the "+1" in "for k=1:+1:10"? Try "for k=1:10" instead.

You cannot change "XTickLabel of figure(100)", because the TickLabels belong to an AXES, not to a FIGURE.

I'm having difficulty finding the problem. This works when I run it. Are you not seeing any numbers on your graph? (You won't see all of them because some are outside the current axis limits and text doesn't resize the axes. That much is expected behavior.)

Either way, I think the best answer to your question "How can i tell [which figure is the CURRENT one] to my function" is to keep the handles to graphics objects and use them, in conjunction with the Parent property:

hfg = figure(100);
hax = axes('Parent',hfg);

% do stuff

text(...,'Parent',hax)

% do more stuff

set(hax,'XTickLabel',...)

% etc

plot(hax,...)  % plots directly into the specified axes
