Can you include screenshots of your app and codes
Create a plot in UIAxes from a table using MATLAB App Designer

I'm trying to create a plot using the data from two colums in a table in the interface, as the following:
func = (app.EditField.Value);
a = (app.EditField_2.Value);
b = (app.EditField_3.Value);
n = (app.EditField_4.Value);
tol = (app.EditField_5.Value);
num = 0;
while (num < n)
fx = 2*tol;
if (abs(fx) > tol)
num = num + 1;
x = a;
fa = eval(func);
x = (a+b)/2;
fx = eval(func);
if (sign(fx) == sign(fa))
a = x;
vars = {num2str(num), num2str(a),num2str(b),num2str(x), num2str(fx)};
app.UITable.Data = [app.UITable.Data; vars];
else
b = x;
vars = {num2str(num), num2str(a),num2str(b),num2str(x), num2str(fx)};
app.UITable.Data = [app.UITable.Data; vars];
end
end
end
t = app.UITable.Data;
middle = t(:, 4);
fmiddle = t(:, 5);
plot(app.UIAxes, middle, fmiddle);
I can not see any errors in plot function, I mean all the arguements are set correctly, but I keep getting the error: 'Not enough arguments'! What is missing in the syntax of plot function? I have reviewed the documentation and everything was correctly added.

When you extract data from the UITable, it is returned in the table data structure. And when you extract any column from this table the also it is returned as a single column table.
Plot accepts data in the array format, that is why you are getting the error.
So you can replace
middle = t(:, 4);
fmiddle = t(:, 5);
with
middle = t{:, 4};
fmiddle = t{:, 5};
Now the 'middle' and 'fmiddle' will contain the data in the array format and it will plotted in the UIPlot.
