Is it possible to create a plot from a table?

I have a table and I'd like to create several plots from it.

Is it easier to create a plot from a table or matrix?

Creating a plot from a table is straightforward, although the references are different —

T1 = array2table(randi(99, 5,3), 'VariableNames',{'Column 1','X','v'})

T1 = 5×3 table
    Column 1    X     v 
    ________    __    __

       96       28    50
       36       18    31
       49       44    45
       58       69    59
       91       54    62

figure
plot(T1.('Column 1'), T1.X, 'p')
hold on
plot(T1.('Column 1'), T1.v, 's')
hold off
grid

If the first column is a datetime array, this is also straightforward —

T2 = table(datetime([2021 11 01])+days(0:4).', rand(5,1), randn(5,1))

T2 = 5×3 table
       Var1          Var2        Var3

    02-Nov-2021     0.35676      0.2072

    05-Nov-2021      0.1249    0.050471

figure
plot(T2{:,1}, T2{:,2}, 'p')
hold on
plot(T2{:,1}, T2{:,3}, 's')
hold off
grid
