Plot multiple columns of table with datetime

Hi, I want to plot multiple (all) columns of a table.

The x axis should be the datetime corresponding to the variables of the column.

My table is in this shape:

P = array2table(rand(288,3),'VariableNames', ["generator", "consumer", "storage"]);

How I was possible to plot all data was:

plot(fig.probax(3), P, P.Properties.VariableNames);

I have a datetime Array:

current_time = datetime('now','Format','yyyy-MM-dd HH:mm');
current_time.Minute = 15 * round(current_time.Minute/15);
datetimeArray = current_time + hours(0:0.25:3*24-2^(-8)).';

And I would like to have the datetimeArray as my x axis but I don't know how I use it in my plot function.

I already know how to show the datetime array in my x axis with

datetick(fig.probax(3),'x', 'HH:mm', 'keeplimits', 'keepticks');

How do I set the x axis of multiple columns of a table?

P = array2table(rand(288,3),'VariableNames', ["generator", "consumer", "storage"]);

current_time = datetime('now','Format','yyyy-MM-dd HH:mm');
current_time.Minute = 15 * round(current_time.Minute/15);
datetimeArray = current_time + hours(0:0.25:3*24-2^(-8)).';

% ax = fig.probax(3);
ax = gca();

plot(ax, datetimeArray, P{:,:});

Thank you that is exactly what I wanted.

You're welcome!

P = array2table(rand(288,3),'VariableNames', ["generator", "consumer", "storage"]);

current_time = datetime('now','Format','yyyy-MM-dd HH:mm');
current_time.Minute = 15 * round(current_time.Minute/15);
datetimeArray = current_time + hours(0:0.25:3*24-2^(-8)).';

% ax = fig.probax(3);
hAx=axes;
plot(hAx, datetimeArray, P.Variables);      % alternative syntax

Use a @doc:timetable instead and then geth stackedplot for free that does it all for you. Use the target figure/panel to place it where you wish in the app; I just let it default for demo as can't create uifgure here.

V=rand(288,3);
current_time = datetime('now','Format','yyyy-MM-dd HH:mm');
current_time.Minute = 15 * round(current_time.Minute/15);
datetimeArray = current_time + hours(0:0.25:3*24-2^(-8)).';
ttP=array2timetable(V,'RowTimes',datetimeArray,'VariableNames', ["generator", "consumer", "storage"]);
stackedplot(ttP)

If you really, really must have the three on one plot, then

figure
subplot(2,1,1)
plot(ttP.Time,ttP{:,ttP.Properties.VariableNames})  % use {} dereferencing table
subplot(2,1,2)                                  % or
plot(ttP.Time,ttP.Variables)                    % use all variables shorthand
