i mean how can i get the data from the table and plot it ,how will the code look like ?

[José-Luis]

What have you tried so far? Where's your time data? What's wrong with:

 plotyy(x1,y1,x2,y2)

i made a figure with 2 axes , a table with 2 columns , i want to plot each column as function of time in two different axes , not in one with 2 y-axes . i tried to get the data of table using this command

data=get(handles.table,'data')

plot(axes1,data(:,column's name ))

i tried this too

M=table(:,column's name ) % as matrix

plot(axes1,t,M);

both ways didn't work , they are the only ways how i thought to plot data from the table

I am sorry, what do you mean by a table? How did you make it?

gui uitable

[José-Luis]

figure(1)
t = uitable; 
set(t,'Data',rand(10,3));
data = get(t,'Data');
figure(2)
aH(1) = subplot(1,2,1);
aH(2) =  subplot(1,2,2);
plot(aH(1),data(:,1),data(:,2));
plot(aH(2),data(:,1),data(:,3));

You need to convert the table data into numbers, and you need the time for the plot. Try this:

data = str2double(get(handles.table,'data');

plot(axes1, t1, data(:,column's name1));

plot(axes2, t2, data(:,column's name2));

[Elia]

a bracket is missing in the first code-line , it didn't work , i become on command window Undefined function or variable 't1'.
