3D - XRD plot

Hi

I wanted to plot 3D waterfall of XRD measurements but even after reading past answeres on the subject I don't succeed..

I have 4 sets of (x,y) as follows:

(Sample A(:,1),y1) % x values are the import of the 1st column from the measurement file that contains many columns but I just need the 1st

(Sample B(:,1),y2)

(Sample C(:,1),y3)

(Sample D(:,1),y4)

the 2D plot looks like this:

How to I make it looks like this?

So far I have:

[x,y]=meshgrid(Sample A(:,1),y1, Sample B(:,1),y2, Sample C(:,1),y3, Sample D(:,1),y4);

waterfall(x,y,z);

not sure what Z needs to be....

How can I continue?

Let's see function plot3 can satisfy your requirement or not.

figure;
ax = gca;
hold(ax,'on');
plot3(ax,SampleA(:,1),repelem(1,1,length(SampleA(:,1))),y1);
plot3(ax,SampleB(:,1),repelem(2,1,length(SampleB(:,1))),y2);
plot3(ax,SampleC(:,1),repelem(3,1,length(SampleC(:,1))),y3);
plot3(ax,SampleD(:,1),repelem(4,1,length(SampleD(:,1))),y4);
hold(ax,'off');
xlabel(ax,'2theta(degrees)');
zlabel(ax,'Intensity (a.u.)');
ylabel(ax,'');
ax.YTickLabel={'(a)','(b)','(c)','(d)'};

for some reason this is the output

Is it possible to attach your data or part of your data?

Sure

I did Sample A and C for you.

For Sample B and D, the number of data are not consistent.

Sample B and D has 9501 and 8501 data, but y2 nad y4 has 9500 and 8508 data respectively. So you need to correct them first.

clear; clc;
SampleA = readmatrix('SampleA-1st colum.xlsx');
y1 = readmatrix('y1.xlsx');
SampleC = readmatrix('SampleC-1st colum.xlsx');
y3 = readmatrix('y3.xlsx');
figure;
ax = gca;
plot3(ax,SampleA,repelem(1,1,length(SampleA)),y1);
hold(ax,'on');
plot3(ax,SampleC,repelem(2,1,length(SampleC)),y3);
hold(ax,'off');
xlabel(ax,'2theta(degrees)');
zlabel(ax,'Intensity (a.u.)');
ylabel(ax,'');
grid(ax,'on');
ax.YTick = [1 2];
ax.YTickLabel={'(a)','(c)'};

It works!

So in order to reproduce this graph to other results each data set should be the same length?

(both x2 same length as y2 as well as x2y2, x3y3 the same length)

Thanks!

[Simon Chan]

Yes, they should be same length.
