Why isn't ezplot holding on?

% settings for figure and axis
figuraT1 = figure('Name',title,'Position', get(0,'Screensize'));
maxfig(figuraT1,1);
assiT1 = axes('Parent', figuraT1);

dim=length(fsymarr);
for i=1:dim
   ezplot(fsymarr(i),[min,max],figuraT1)
   hold on 
end
grid on
set(assiT1, 'LineWidth',1.5);
set(assiT1,'FontSize',14,'FontWeight','bold','FontAngle','Italic');
ylabel('Y Values');
xlabel('X Values');

Why does the function ezplot plot only the last function in the array fsymarr?

What is class(fsymarr) ?

[Alessio Nava]

It is an array where there are some functions which need to be plotted on the same graph; they represent the domain of a function in multivariable problem. I'd like to plot them if their domain is in R2 but ezplot isn't holding on...

[Walter Roberson]

What does

class(fsymarr)

show ? I need to know in order to tell you the correct solution.

Also I will need to know your MATLAB version number.

[Alessio Nava]

fsymarr is a simple vector containing explicit 2D functions expressed in symbolic vars. For example it might contain: [x^2+1, sqrt(x)]. I iterate over the vector fsymarr to plot all these functions on the same graph.

The only thing I see at the moment is that ezplot() automatically adjusts the plot limits in ways such that the results of the earlier plot might only be partly visible (or out of range completely.)

Try changing to "hold on" instead of "hold all" -- but note that if you do that then the limits established first will be used, possibly leaving other plots mostly out of window.

[Alessio Nava]

That was the problem; unfortunately I did not realize since all the graphs are complementary. I've just written some code which manages to resize the axis dinamically. Thank you very much!

Hello Alessio Nava, I have the same problems with "hold on" and "ezplot", the axes change and the graph does not come out well. Could you give me some indication about your code, I would really appreciate it. Thank you.
