I have 2 data sets in Kitap 1 and PLMS. I want to show this 2 datasets with different colours in one 3D scatter. I wrote this code but I have only yellow points with this. Can somebody help me for 2 different colours.
x=data(1:end,1);
y=data(1:end,3);
z=data(1:end,5);
xx=data2(1:end,1);
yy=data2(1:end,4);
zz=data2(1:end,3);
figure(1);
scatter3(xx,yy,zz,'r','filled');
hold on
scatter3(x,y,z,'y','filled');
hold off
grid on
xlabel('X(km)')
ylabel('a(m/s^2)')
zlabel('CO_2 emission(g/s)')
zlim([0 100])

@Gulfem Atasayar Can you provide the Kitap1 and PLMS files?
Because in my end I can plot 2 different data in 2 different colours successfully (Refer the code below).
close all; clc;
% Random data1
x = 1:200;
y = 1:200;
z = rand(1, 200);
% Random data2
xx = 1:200;
yy = 1:200;
zz = rand(1, 200);
figure; scatter3(xx, yy, zz, 'r', 'filled');
hold on;
scatter3(x, y, z, 'y', 'filled');
hold off; grid on;
xlabel('X(km)'); ylabel('a(m/s^2)'); zlabel('CO_2 emission(g/s)'); Gulfem Atasayar on 12 Feb 2020
Here there are :)

Firstly your PLMS.xlsx file has some NaN values. Moreover, the variable x is identical with xx, y is identical with yy, and so on...
Therefore, the first scatter plot is being overlapped by the second scatter plot.
I have increased the marker size of the first scatter plot and decreased the marker size of the second scatter plot in the code below. It is clearly visible how the first scatter plot is being overlapped by the second scatter plot.
Hope this helps!
clc; close all;
x = data(1:end, 1);
y = data(1:end, 3);
z = data(1:end, 5);
xx = data2(1:end, 1);
yy = data2(1:end, 4);
zz = data2(1:end, 3);
xx(isnan(xx)) = [];
yy(isnan(yy)) = [];
zz(isnan(zz)) = [];
figure;
scatter3(xx, yy, zz, 100, 'r', 'filled');
hold on;
scatter3(x, y, z, 40, 'y', 'filled');
hold off;
grid on;
xlabel('X(km)');
ylabel('a(m/s^2)');
zlabel('CO_2 emission(g/s)'); #### 1 Comment
