Issues Creating Multiple Figures in Same Script
显示 更早的评论
Hello, I'm looking to create a series of figures in a script, each figure should have multiple plots in it. I cannot seems to get the behavior I'm looking for however.
I've tried to use 'hold on' and 'hold off' but the script appears to completely ignore this and just throw every plot into the same figure seemingly any time I invoke "hold" at all. Adding some axes and trying to separate them that way has resulted in a perfect figure if I run it only for a single figure, but a mess with overlaid axes and titles with no data in it if I try to run all three. The current code I'm using to try and generate the figures is below. Any help would be appreciated.
position_1 = a1_sol.a0 + 0*t + a1_sol.a2*t^2 + a1_sol.a3*t^3
position_2 = a2_sol.a0 + 0*t + a2_sol.a2*t^2 + a2_sol.a3*t^3
pathq1 = subs(position_1);
pathq2 = subs(position_2);
axis1 = axes;
hold(axis1,'on')
fplot(axis1,pathq1,[0,5])
fplot(axis1,pathq2,[0,5])
title('Joint Positions vs Time')
hold(axis1,'off')
velocity_1 = diff(position_1);
velocity_2 = diff(position_2);
velq1 = subs(velocity_1);
velq2 = subs(velocity_2);
axis2 = axes;
hold(axis2,'on')
fplot(axis2,velq1,[0,5])
fplot(axis2,velq2,[0,5])
title('Joint Velocities vs Time')
hold(axis2,'off')
acceleration_1 = diff(velocity_1);
acceleration_2 = diff(velocity_2);
accq1 = subs(acceleration_1);
accq2 = subs(acceleration_2);
axis3 = axes;
hold(axis3,'on')
fplot(axis2,accq1,[0,5])
fplot(axis2,accq2,[0,5])
title('Joint Accelerations vs Time')
hold(axis3,'off')

Wouldn't the following make more sense?
position_1 = a1_sol.a0 + 0*t + a1_sol.a2*t^2 + a1_sol.a3*t^3
position_2 = a2_sol.a0 + 0*t + a2_sol.a2*t^2 + a2_sol.a3*t^3
pathq1 = subs(position_1);
pathq2 = subs(position_2);
figure
subplot(3,1,1)
fplot(axis1,pathq1,[0,5])
hold on
fplot(axis1,pathq2,[0,5])
title('Joint Positions vs Time')
hold off
velocity_1 = diff(position_1);
velocity_2 = diff(position_2);
velq1 = subs(velocity_1);
velq2 = subs(velocity_2);
subplot(3,1,2)
fplot(axis2,velq1,[0,5])
hold on
fplot(axis2,velq2,[0,5])
hold off
title('Joint Velocities vs Time')
acceleration_1 = diff(velocity_1);
acceleration_2 = diff(velocity_2);
accq1 = subs(acceleration_1);
accq2 = subs(acceleration_2);
subplot(3,1,3)
fplot(axis2,accq1,[0,5])
hold on;
fplot(axis2,accq2,[0,5])
title('Joint Accelerations vs Time')
hold off
