Hi all,
I have temperature data for different depths over time. I'd like to display it with a coloured line plot that shows lines at the different depths filled with the temperature gradients over time (see example below). Attached are variables of depth, time and temperature for 0 meters. Anyone can give some help on how to do this?
Thank you in advance!!

The patch documentation section on Create Multicolored Line offers one option.
The problem with the data is that the temperature does not vary much with the depth, and then only at the ends —
load('temp0')
load('depth0')
load('time0')
whos
Name Size Bytes Class Attributes ans 1x34 68 char cmdout 1x33 66 char depth0 39577x1 316616 double temp0 39577x1 316616 double time0 39577x1 316648 datetime
temp0s = [min(temp0) max(temp0)]
temp0s = 1×2
13.0732 29.4457
depth0end = depth0(end);
depth0(end) = NaN;
figure
patch(time0, -depth0, temp0, 'EdgeColor','interp')
hold on
scatter(time0(end), -depth0end, 5, temp0(end), 'filled', 's')
hold off
cb = colorbar;
cb.Label.String = 'Temperature (°C)';
colormap(turbo)
xlabel('Time')
ylabel('Depth')
figure
plot3(time0, -[depth0(1:end-1); depth0end], temp0, ':k', 'LineWidth',0.25)
hold on
scatter3(time0, -[depth0(1:end-1); depth0end], temp0, 3.5, temp0, 'filled', 's')
hold off
cb = colorbar;
cb.Label.String = 'Temperature (°C)';
colormap(turbo)
grid on
xlabel('Time')
ylabel('Depth')
zlabel('Temperature')
.

Thanks Walter! I saw those file exchanges but not sure how to apply it to my data (quite new to Matlab).
The syntax of the file exchanges has sin and cos (e.g. y=sin(4*pi*x);z=cos(4*pi*x);), don't know how to use it with my data.
Any idea?
Thank you!

x=datenum(time0)
y=depth0
z=temp0
c=z
W=3
p=clinep(x,y,z,c,W);
colorbar
caxis([14 16])
set(gca, 'YDir','reverse');
This came out using this code. How can I add the other sensors? Thank you!
