Mohammad - your attached file does not include the pushbutton2_Callback nor do I see any reference to an f or h. I can reproduce your error with this code
>> plot(1:10, 'hello')
where the second input, the string 'hello', is not a valid color or linetype argument. I suspect that you have the same problem with your h variable. What is it set to?

When I run the above code (with some dummy inputs), h becomes a 1x1 char with a value of '0' and so the plot function thinks that it should be a colour or line type. The code to set h is as follows
h=((s.*n.*str2double(c))/(1+(s.*n.*str2double(c))));
h=num2str(h);
Why are you converting it to a string with num2str? If I remove this line then h remains as an array and something is drawn on the axes...
