So I have a file which contains the accelerometer values of a phone. The CSV file contains time, x, y and z columns. I am trying to find a way to plot the 3 axes (x, y and z) vs. time into one graph rather than using 'stackedplot'. How would one go about this?

% making up some data:
t = 0:0.01:10;
x = cos(t);
y = sin(t);
z = t;
% plot x,y,z vs t in one plot:
figure();
plot(t,x,t,y,t,z);
legend('x','y','z');
xlabel('t');
grid on
% or make a 3d line whose points are (x,y,z):
figure();
plot3(x,y,z);
xlabel('x');
ylabel('y');
zlabel('z');
box on
grid on

x_back_accel = cell2mat(backside_accel(:,1));
y_back_accel = cell2mat(backside_accel(:,2));
z_back_accel = cell2mat(backside_accel(:,3));
plot(t,x_back_accel,t,y_back_accel,t,z_back_accel);
Convert them to double array and plot it.

You can use readmatrix function instead of readtable when importing data and to plot them using your initial code without having to use cell2mat
backside_accel = readmatrix('Lab5-Phone-BackSide/accelerometer.csv');
t = 0:0.1:4;
x_back_accel = backside_accel(:,1);
y_back_accel = backside_accel(:,2);
z_back_accel = backside_accel(:,3);
figure()
plot(t,x_back_accel,t,y_back_accel,t,z_back_accel);
