Problems creating stacked plots on MATLAB

I would like to make a stacked plot of 3 y-axis variables, with variable 'time' on the x-axis. I have looked at the help function for stacked plot but I don't understand it. Do I need to create a table before making the stacked plot? I tried

The variables that I want on the y-axis are:

spiketimes : 1 x 100 double (it's a vector of times). I would like this to be as a raster plot.

transmit_times: 1 x 92 double (it's a vector of times). I would like this to be as a raster plot.

Probability: 1 X 10001 double. I would like a normal line graph for this

On the x-axis:

Time: 1 x 10001 double.

What do you mean by "raster plot", precisely?

You can plot your long time vector and the probablilty that goes with it easily enough...

figure
plot(T,P)
hold on
% now the others...

The problem there is it isn't at all clear what you expect to do with the two shorter vectors of other time data...you can certainly plot at whatever time points you have on the same axis, but just what is it to be plotted against those times--we seem to be out of data.

Thanks. By raster plot, I mean something like I have below. I'm not sure I can use the hold on function because the quantities being measured on the y-axis are different. There's a stackedplot function on MATLAB but can't figure out what to do from the help.

That's just a scatter() plot with a constant value of unity at the time points. There's no need for stacked plot; by a "stacked" plot I think of area, nothing like this.

Of course you can use hold on; this type of thing is precisely what it's there for...add more stuff to the plot besides just the initial line.

Now if you're trying to plot totally disparate ranges of y values on the axis, then "Yes, Virginia, we may have a problem!" but there what you're looking for is probably two y axes. See

doc yyaxis

for details and examples.

Thanks. I ended up using the subplot function.

[dpb]

Well, "if you're ok, I'm ok!" but if you would show just what you are trying to plot with some sample data if the subplot() isn't exactly what you had in mind, it's probably not difficult to do something much more like what you envisioned originally.

The subplot works. I created a subplot of 5 x 1 layout to get something like this
