i used this code
This code was used to find the Relationship of DEq, CTDIvol and scanning length, also the code was used to show the error bar for DEqvalues (The error bars for all DEqvalues are difficult to see in the graph , so I multiplied them by 5)
% x= CTDIv
x=[2.6,5.2,14,23.3,28.3,2.6,5.2,14,23.3,28.3,2.6,5.2,14,23.3,28.3 ];
% y= planar average equilibrium dose (DEq)
y=[3.5,6.9,17.7,29.1,35.2,3.5,6.8,17.5,28.7,34.8,3.4,6.6,16.9,27.6,33.5 ];
% z= scanning length
z=[450,450,450,450,450,350,350,350,350,350,250,250,250,250,250];
% ysd= DEq standard deviation
ysd = [0.047140452, 0.047140452, 0.047140452, 0.124721913, 0.047140452, 0.047140452, 0.047140452, 0.047140452, 0.124721913, 0.124721913, 0.047140452, 0.047140452, 0.047140452, 0.124721913, 0.124721913];
xr = reshape(x, [], 3);
yr = reshape(y, [], 3);
zr = reshape(z, [], 3);
ysdr = reshape(ysd, [], 3)*5;

figure
hold on
for k1 = 1:size(xr,2)
for k2 = 1:size(xr,1)
plot3((xr(k2,k1)*[1 1]), (yr(k2,k1)+ysdr(k2,k1)*[-1 1]), (zr(2,k1)*[1 1]), '-r')
plot3((xr(k2,k1)), (yr(k2,k1)), (zr(2,k1)), '.r')
end
end
hold off

grid on
the Error bars are too small in the figher as i have attached . and i want to Increase the dot size and fit a grid or lines to the dots ??

I'm so confused. Could artificially increasing dot size have resulted in the dot-com bust? ;-)
(Sorry, really.)

Specify the MarkerSize name-value pair argument when you call plot3. See the "Customize Color and Marker" example on that page.

plot3((xr(k2,k1)), (yr(k2,k1)), (zr(2,k1)), '.r', 'MarkerSize', 20)
