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")

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;
