Error using tabular/plot Too many input arguments.

I am trying to plot 4 lines on the same graph and i keep getting the following error message

Error using tabular/plot
Too many input arguments.

I have entered it two ways, and gotten the same response

hold on
plot(E1var1a,E1var1b)
plot(E1var1a,E1var1b)
plot(E1var2a,E1var2b)
plot(E1var3a,E1var3b)
plot(E1var4a,E1var4b)
hold off

and

plot(E1var1a,E1var1b,E1var2a,E1var2b,E1var3a,E1var3b,E1var4a,E1var4b)

Walter Roberson Thank you for your answer. You were correct. I was using () instead of {}. Although question is asked by someone else, It helped me. So, thank you.

Answer 1

[Walter Roberson]

It is not possible to plot() a table object. If you were to happen to ask to plot() a single table object then it would tell you that there is no function named plot() for that data type, but it happens that if you try to plot() a table object and list more than one entry, the error will be caught by different code that will give you the error about too many inputs.

You need to extract data from the table object in order to plot it.

If you thought you already had extracted the data from the columns, then you probably accidentally used something like

E1var1a = YourTable(:,1);

where you should have used

E1var1a = YourTable{:,1};

or

E1var1a = YourTable.E1var1a;

That's very help, although it wasn't me who asked the question, but still, thanks!
