Suppose I have table T
date visiors sales
1/1/2021 3 100
1/2/2021 5 120
I want to draw a plot of "visitors" and "sales" with date on the x axis. How can one do this?

If you want a simple line plot, you could do
plot(, T.visitors)
hold on
plot(, T.sales)
plot(, [T.visitors T.sales])
or even:
plot(, T.visitors,, T.sales)
For a bar chart you might do:
bar(, [T.visitors T.sales])

You can do this with:
stackedplot(T, {{'visitors' 'sales'}}, 'XVariable', 'Date')
The {{ might be confusing: you can think of this as: each element of the outer cell is an axes, each element of the inner cell is a line in that axes.
This definitely makes more sense when you have multiple plots to 'stack'.
