I can’t determine why it’s not automatically displaying.
Use the view (link) function to make it magically appear: 
Fspace = rand(400,3);
figure
hold on;
plot3(Fspace(1:300,1),Fspace(1:300,2),Fspace(1:300,3),'b*');
plot3(Fspace(301:400,1),Fspace(301:400,2),Fspace(301:400,3),'ro');
hold off
legend('Class A','Class B');
% axis equal;
xlabel('x');
ylabel('y');
zlabel('z');
title('original data');
grid on
view(-30, 45)
