Attached is a picture of a side view of a 3-D surf plot I have created using surf(X,Y,Z,'edgecolor','interp').

The X axis is the date, Y axis is the depth, Colobar represents the temperature.

I want to find the temperature values at a specified y value. For example, is there a way to find all the plotted points and their temperature values at Y = 1?

Hope that makes sense.

Thanks for the help!

Read about slice.

Also you can find the index of your required points and extract the required values.

Thanks for the help.

I am looking into slice. My X is 5042 x 1 datetime, y is 1x6 double, Z is 6x5042 double.

I am not sure what 'V' for the slice function should be in this case, could you offer any advice?

You can get the index of your y; you got only 6 values for y.
