Multiple Lines in a Stacked Plot

I'd like to have 3 different vectors plotted onto 2 graphs within a stacked plot. For example, I wish to plot vectors a and b in the first graph of the stacked plot and variable c on the second graph, with the x-axis of the stacked plot being another vector, t. How would I be able to do that?

If you are working with R2018b or a later version, check out stackedplot

%Random data
n = 10;
t = (1:n).';
a = zeros(n,1);
b = ones(n,1);
c = rand(n,1);

data = table(t, a, b, c)

data = 10×4 table
    t     a    b       c    
    __    _    _    ________

     1    0    1     0.89507
     2    0    1    0.099055
     3    0    1     0.70476
     4    0    1     0.65991
     5    0    1     0.78316
     6    0    1     0.80992
     7    0    1     0.32504
     8    0    1     0.10411
     9    0    1      0.6188
    10    0    1     0.34006

vars = {["a" "b"], "c"};
stackedplot(data, vars, "XVariable", "t")

It worked! An additional question: how can I change the visual properties (say, color) of those lines on the first lot individually? I can only seem to change the color of both a and b.

You can access the properties of the stackedplot by getting the StackedLineChart Properties object and then modifying as per need/requirement/liking -

%Random data
n = 10;
t = (1:n).';
a = zeros(n,1);
b = ones(n,1);
c = rand(n,1);

data = table(t, a, b, c)

data = 10×4 table
    t     a    b       c   
    __    _    _    _______

     1    0    1    0.92642
     2    0    1    0.16481
     3    0    1    0.16602
     4    0    1    0.72322
     5    0    1    0.89256
     6    0    1    0.54806
     7    0    1    0.49016
     8    0    1      0.643
     9    0    1    0.66422
    10    0    1    0.29326

vars = {["a" "b"], "c"};
s = stackedplot(data, vars, "XVariable", "t");
arr = s.LineProperties

arr = 
  2×1 StackedLineProperties array with properties:

    Color
    MarkerFaceColor
    MarkerEdgeColor
    LineStyle
    LineWidth
    Marker
    MarkerSize
    PlotType

%Get the color of the first plot
col = arr(1).Color

col = 2×3

0 0.4470 0.7410 0.8500 0.3250 0.0980

%Change the color of the first plot
new_col = hsv(size(col,1))

new_col = 2×3

1 0 0 0 1 1

arr(1).Color = new_col;

Works great, thank you so much!
