Why do I receive a subplot error?

figure(1)

hxl= subplot(scatter(height,leg));

lsline(hxl);

polyfit(height,leg,1);

title('Height v. Leg Length');

xlabel('Height (cm)');

ylabel('Leg Length (cm)');

%figure(2)

hxf= subplot(scatter(height,foot));

lsline(hxf);

polyfit(height,foot,1);

title('Height v. Foot Length');

xlabel('Height (cm)');

ylabel('Foot Length (cm)');

%figure(3)

hxs= subplot(scatter(height,speed));

lsline(hxs);

polyfit(height,speed,1);

title('Height v. Speed');

xlabel('Height (cm)');

ylabel('Speed (m/s)');

%figure(4)

lxs= subplot(scatter(leg,strl));

lsline(lxs);

polyfit(leg,strl,1);

title('Leg Length v. Stride Length');

xlabel('Leg Length (cm)');

ylabel('Stride Length (distance/stride)');

% Find the R^2 and p-value for each linear fit.

% Use command fitlm(x,y)

fitlm(height,leg)

fitlm(height,foot)

fitlm(height,speed)

fitlm(leg,strl)

Error using subplot (line 197)

Requires valid axes handle for input.

Error in WalkingSpeed (line 49)

subplot(scatter(height,leg));

That’s not how subplot works.

It should be something like this —

figure(1)
hxl = subplot(2,2,1);
scatter(height,leg)
lsline
% polyfit(height,leg,1);
title('Height v. Leg Length')
xlabel('Height (cm)')
ylabel('Leg Length (cm)')

%figure(2)
hxf = subplot(2,2,2);
scatter(height,foot)
lsline
% polyfit(height,foot,1);
title('Height v. Foot Length')
xlabel('Height (cm)')
ylabel('Foot Length (cm)')

%figure(3)
hxs= subplot(2,2,3);
scatter(height,speed)
lsline
% polyfit(height,speed,1);
title('Height v. Speed')
xlabel('Height (cm)')
ylabel('Speed (m/s)')

%figure(4)
lxs = subplot(2,2,4);
scatter(leg,strl)
lsline
% polyfit(leg,strl,1);
title('Leg Length v. Stride Length')
xlabel('Leg Length (cm)')
ylabel('Stride Length (distance/stride)')

That should work, although it may be necessary to tweak it to get the desired result.

That worked thank you!

As always, my pleasure!
