Hi
I've try working on making a times-series vs depth vs Uspeed plot as picture attached whole day, I try XYGridandZtomatrix but result didn't seem well, after that I found following code to interpolate, but I can't let my time-series interpolate, can anyone tell me how to make a XYZ plot as picture attached, thank you.
macro test()
killwaves/a/z
killvariables/a/z
killstrings/a/z
Make/O/N=20 xWave=enoise(4),yWave=enoise(5),zWave=enoise(6) // Random points
Display yWave vs xWave
ModifyGraph mode=3,marker=19
ModifyGraph zColor(yWave)={zWave,*,*,Rainbow,0}
Concatenate/O {xWave,yWave,zWave}, tripletWave
ImageInterpolate/S={-5,0.1,5,-5,0.1,5} voronoi tripletWave
AppendImage M_InterpolatedImage

Your test data is not nearly dense enough to make image and contour plots that look anything like that.
Perhaps you can share your actual data.
These plots are really easy to produce with Igor given the right data.

In reply to Your test data is not nearly… by JimProuty
First, thank you for your reply, I upload my data as attached, I got current profile for 16 layers, every file include 6 variables as following.
I think my data is quite dense to make image and contour, maybe I misunderstand how to make the plot.
1.date/time
2.vector u (eastward current velocity)
3.vector v (northward current velocity)
4.current speed
5.current direction
Sincerely yours

What value do you assign to each layer? is it depth? How is it computed?

Sorry, I forgot to mention where did I mark the depth.
Each file name include depth, I mark it on the attached picture, and every file contain date/time, U, V, speed and direction in time-series. These data were output by observation instrument.

I looked at this a little bit, and doubt that the noisy data will contour well.
I've attached my attempt to make a graph like you showed using your data, assuming that a file ending with "_004.check" meant it was recording a depth of 4 meters, and _012 was 12 meters.
I think you wanted z = either U or V at various depths (Y) for various times (X).
I loaded each file's contents into a data folder keyed by file name, which I assume corresponds to one depth.
See attachments for experiment and screenshots.
