How to plot multiline with variable inputs

I have vibration data from several components, and I'm trying to create a multi line plot that allows the user to select multiple variables versus time. I can easily script a multi line plot, but I want to make the number of dependent variables flexible, rather than static.
Instead of scripting "plot(x, y1, x, y2, ..., x, yn), I'd like to pass a variable as an index that references the table where the x and y values are stored.
For example: plot(x, vars(:,3), x, vars(:,4)..., x, vars(:,n))
{where x = vars(:,1) or vars(:,2), which are independent variables in my data table}
Is it possible to make the plot function dynamically sized based on the user input?
Thanks in advance

Up to my understanding of your question, I think you are struggling to plot.
You can try this one. Sorry, if I misunderstood your question.
A={rand(1,10),rand(1,10),rand(1,10),rand(1,10)}
col={'g','k','b','r'}
for ii=1:4
plot((1:10),A{ii},col{ii})
hold on
end

There is no point in making this so complicated: no slow ugly loop or complex code is required. All you need is
plot(x, vars)
because plot will plot the columns of vars against x. You can easily add indexing as required, e.g.:
plot(vars(:,2),vars(:,4:end))
