How to plot all curves according to their XY coordinates?

Hi,

In the figure attached below, each VT curve have XY cordinates. I want to plot these curves according to the XY coordinate position. How I can write my figure code. Suppose the X nd Y coordinates of first line (left side) are ''XY location X = 458158.62, Y = 6526223.5''. Similarly all the other curves have XY location values. How I can incorporate XY positions in such a way that these plots are according to respective coordinates.

As you have (x,y) coordinates in hand, striaght away you can use plot.

It's not at all clear to me what you would expect the resulting plot to look like...you have a series of traces of something already with a set of 2 variables to produce the above. If each trace is the recording of whatever these variables are versus som other set of coordinates/variables, best I can see would be maybe(?) a surface of one of these as the z coordinate vs the x,y.

I dunno, can't visualize what we're trying to do here from the limited information, sorry...as per usual, attaching the data as a .mat file plus in this case, perhaps a sketch of the desired result or an example of such a plot from similar data from another source would help...

The curves are already plotted to a set of (x,y) coordinates. How do the (x,y) coordinates that define the currently plotted lines differ from the (x0,y0) coordinates you'd like to plot? A brief demo may be helpful.

Hi @dpb

I have attached .mat file, have VP, TWT, XY coordinates

[KSSV]

The give file has a single (X,Y) data. And all these points are same.

[Nisar Ahmed]

@KSSV. It is because single XY for each plot represents its poistion, these are xy coordinates, these are the horizontal and vertical addresses of any pixel

What we also need is the line(s) of code you used to generate the figure.

Hi @dpb, @KSSV and @Adam Danz

Now I have z file as well. Please see the attached data:

I want to plot imagesc(d, TWTi, vp). I mean TWTi along y axis and is common for all vp curves. while d is the distance between each vp curve.

Can you please help me to produce a figure?

[Adam Danz]

Sorry, but I really don't know what the question is. If you want to plot imagesc(d, TWTi, vp), what's preventing you from doing so? And how does that relate to the line plot in your question?

load d_data.mat
load TWTi_data.mat
load vp_data_plotting.mat

vpmax = max(vp(:));
vpmin = min(vp(:));
vpave = mean(vp(:));

deltad = (max(d)-min(d))/length(d);

v = (vp - vpave)/(vpmax-vpmin) * deltad * 2 + d;
subplot(121)
plot(v, TWT1i);
set(gca,  'YDir', 'reverse');
xlabel('d');
ylabel('z');

subplot(122);
p = pcolor(d, TWT1i, vp);
p.EdgeColor = 'none';
axis ij
colorbar

Hi @Chunru, thank you but I ma looking for color display, like plot as imagesc or surf

like as

[Chunru]

See above.

[Nisar Ahmed]

Thank you @Chunru, how can I change the color like jet or any else?

[Chunru]

For example:

colormap(jet(512))
