Hi all,
I am currently doing a 3D figure with 3 differents 2D-plots (representing 3 conditions)
1) How can I fill the area under the ploted curves ? It is currently filling the area from the top of the curve up to a random horizontal axis
I previously used the fliplr tool but does not work at the moment here ...
2) How can I invert the y-axis (currently going from 100 to 0, and needs to be from 0 to 100)
Thanks a lot
figure
y = Data{:,1};
z = Data{:,2};
x = Data{:,3};
fill3(x,y,z,[0.00,0.45,0.74],'LineStyle','none','FaceAlpha',.3)
hold on
y = Data{:,1};
z = Data{:,4};
x = Data{:,5};
fill3(x,y,z,[0.04,0.49,0.35],'LineStyle','none','FaceAlpha',.3)
hold on
y = Data{:,1};
z = Data{:,6};
x = Data{:,7};
fill3(x,y,z,[1.00,0.00,0.00],'LineStyle','none','FaceAlpha',.3)

I am not certain what result you want with respect to ‘under the plotted curves’. Adjusting that limit (defined here as ‘min(Data{:,2+2*(k-1)})’) is relatively straightforward if you want to change it.
Try this —
LD = load('Data.mat');
Data = LD.Data
c = 'bgr';
figure
x = Data{:,1};
hold on
for k = 1:3
% Q = [2+2*(k-1); 3+2*(k-1)]
% plot3(Data{:,3+2*(k-1)}, x, Data{:,2+2*(k-1)})
patch([Data{:,3+2*(k-1)}; flip(Data{:,3+2*(k-1)})], [x; flip(x)], [Data{:,2+2*(k-1)}; zeros(size(x))+min(Data{:,2+2*(k-1)})], c(k), 'FaceAlpha',0.5, 'EdgeColor','none')
end
hold off
grid on
view(-30,30)
