When you execute the code below, two plots are drawn.
However, I want to combine these two plots and make them into one plot. What should I do?
figure(1)
plot(x,ys,'m')
hold on
%%%%%%%%adding vertical lines%%%%%%%%
n = 20; %%%%%%%% number of lines %%%%%%%
x_ref = 7800;
xx=linspace(x(1)+100,x(end)-100,n);
yy = interp1(x,ys,xx);
for ci=1:n
plot([x_ref+(ci-n/2)*50 xx(ci)],[0 yy(ci)],'r');
pause(0.05);
end
hf = figure()
ha = axes()
hp1 = plot(hip_y, hip_z, 'o')
hold(ha,'on')
hp2 = plot(knee_y, knee_z, 'o')
hp3 = plot(ankle_y, ankle_z, 'o')
hp4 = plot(tarsal_y, tarsal_z, 'o')

‘When you execute the code below, two plots are drawn.’
No, not without knowing what the variables are.
However the problem is that the beginning of the (posted) code creates ‘figure(1)’ then after the loop, another figure appears and is assigned to ‘hf’, so everything subsequent to it is plotted in the second figure.
Use hold and eliminate the second figure call and it should work as desired.
