Plotting a semilogx plot with a table

I'm trying to plot two tables (Final & Inital, both 201x2) using the semilogx function.

Here's how I'm trying to do it.

subplot (2,1,1)
    semilogx(Initial{:,1},Initial{:,2})
    title('Final & Initial Measurements')
    xlabel ('Frequency'); ylabel('Magnitude')
    hold on
    semilogx(Final(:,1),Final(:,2))
    xlabel ('Frequency (Hz)'); ylabel('Magnitude (dB)');
    legend('InM'+n+'','FM'+n+'');
    hold off

But it keeps throwing the error

    Error using semilogx
Data must be numeric, datetime, duration or an array convertible to double.

How do I get around this?

Thank you for any help!

semilogx(Initial{:,1},Initial{:,2})

That line you got right

    semilogx(Final(:,1),Final(:,2))

But not that one.

Notice that the first time you used {} indexing but the second time you used ()

Ah I feel silly, thank you so much!
