now I want to call my function like:

Answer 1

You can use inputname to get the name of the input in the calling workspace and then pass this to legend or set the DisplayName property of the plot to this value.

function example(x1)
    figure
    plot(x1.time, x1.value)
    legend(inputname(1))
end
