MATLAB: plot timetable matrix

Question

I would like to plot all columns of a timetable. For example, let's say, I have a timetable with two columns.

time = datetime({'2017-11-15'; '2017-11-18'; '2017-11-19'});
col1 = [NaN;4;5];
col2 = [7;6;4];
tt = timetable(time, col1, col2);

How can I plot all columns (line chart)?

Let me add three things:

1. I don't know the column titles in advance.
2. I don't know the number of columns in advance.
3. The first columns might not necessarily be the longest column (see NaN).

Answer 1

There's an even less complicated version. :-)

plot(tt.time, tt.Variables);

Answer 2

Take a look at varfun :

>> ax = axes('NextPlot','add');
>> varfun(@(v) plot(ax,tt.time, v), tt)

Answer 3

从 R2018b 版本开始， stackedplot函数使这变得更加容易，这是stackedplot ：

stackedplot(tt)
