Error using ==> plot Vectors must be the same lengths.

Hi! I have three input Mux to Scope. Run the simulation.Open the Scope block, select Parameter. Select the Data history tab, select the Save data to workspace. not select the Limit data points to last. select the type of structure with time.To graph out window Commandwindow, I use the command:

 figure(1);
 plot(ScopeData.time,ScopeData.signals.values(:));
 grid on;
??? Error using ==> plot
Vectors must be the same lengths.

why? please help me!

You have to have an x and y variable that are the same length

So

ScopeData.time and ScopeData.signals.values(:)

do not have the same length

For instance

    x = 1:10;
    y = randn(11,1);
    plot(x,y)

So you should determine what the dimensions (sizes) are of

gives the same error. ScopeData.time and ScopeData.signals.values

If you need to, put a breakpoint on that line in the code that plots and then you can put your cursor over the inputs to see their sizes.
