a function that draws a plot: use a variable name for a legend

I have a data for

days
temperature

I want to write a function that plot(x,y) that, when one inputs plot(days,temperature), that outputs

plot(days, temperature)
legend('days','temperature')

So I start with

function plottest(x,y)
plot(x,y)
end

Now how should I write

legend

?

If you want to get the variable name inside a function, you can use the "inputname" function:

function plottest(x,y)
plot(x,y)
legend(inputname(1),inputname(2))
end

However, in your plot you only have one "y" variable, so it does not make sense adding several legends. Maybe you want to change the label of the axes? In this case:

function plottest(x,y)
plot(x,y)
xlabel(inputname(1))
ylabel(inputname(2))
end
