Draw 3 D from 4 data sets

How I can draw 3 D from the these data to get graph as atteched?

x1 = [60 65 70 75 80 85 90 95]

y 1= [717.7443511 450.2110549 315.3203173 281.0355881 310.2619146 367.5904781 425.4810863 466.5103523]

x2 = [32 34 36 38 40 42 44]

y2 = [2461.769179 2698.95206 2893.41954 2863.069124 2539.331353 1964.921629 1246.066407]

With the given data it is not possible to get the plots shown as attached.

You either need to pick 3 of the 4, or provide an equation for Z based on the values of X and Y.

Consider taking a look at some of the examples on the documentation page for surf.

Thank you for your replies

what about these data?

LL = [50.0 60.0 70.0 80.0 90.0 100.0 110.0]

UCS = [2695.6 1417.5 671.1 403.6 412.6 510.3 621.1]

PL = [15.0 20.0 25.0 30.0 35.0 40.0 45.0]

UCS = [9467.7 5552.5 2276.9 535.1 476.1 671.1 128.2 ]

I dont have equation for z

The values i got them from tests on soil

[Ghufran Aldawood]

The data sets that you have don't have the same dimensions, if you have the same dimension on all sets, I assume you want to use the fourth set for color gradient. For that you can use the patch function in Matlab. I've attached code and figures.

[Asma A Bder Muhmed]

Ghufran Aldawood thank you

I've tried the code but I coudnt apply the data

if possoble, I need the UCS values to be in z axis

below are new data with same demintions

LL = [50.0 60.0 70.0 80.0 90.0 100.0 110.0]

UCS = [2695.6 1417.5 671.1 403.6 412.6 510.3 621.1]

PL = [15.0 20.0 25.0 30.0 35.0 40.0 45.0]

UCS = [9467.7 5552.5 2276.9 535.1 476.1 671.1 128.2 ]

[Ghufran Aldawood]

PL = [15.0  20.0  25.0  30.0  35.0  40.0  45.0];
UCS = [9467.7  5552.5  2276.9  535.1  476.1  671.1  128.2];
LL = [50.0  60.0  70.0  80.0  90.0  100.0  110.0];
figure(1)
stem3(PL, UCS, LL)
grid on
PL2 = linspace(min(PL), max(PL), 20);
UCS2 = linspace(min(UCS), max(UCS), 20);
[X,Y] = meshgrid(PL2, UCS2);
Z = griddata(PL,UCS,LL,X,Y);
figure(2)
surf(X, Y, Z);
grid on
set(gca, 'ZLim',[0 100])
shading interp

Thank you for your help.

In your code you just include one UCS where for each LL there is UCS value

the same for PL. is there what make the UCS values to be in z axis?

LL1 = [50.0 60.0 70.0 80.0 90.0 100.0 110.0]

UCS 1 = [2695.6 1417.5 671.1 403.6 412.6 510.3 621.1]

PL 2 = [15.0 20.0 25.0 30.0 35.0 40.0 45.0]

UCS 2 = [9467.7 5552.5 2276.9 535.1 476.1 671.1 128.2 ]

[Ghufran Aldawood]

You can't graph in 3D with 4 data sets.

[Asma A Bder Muhmed]

Thank you I thought it is possible where I have 3 variables LL,PL, UCS But with different values for ucs

[Ghufran Aldawood]

You have UCS 1 which is one variable, and UCS 2 which is a second variable. It does not matter that they have the same name. For example, here are 3 variables:

X1 = 1,5,10,15,20

X2 = 1,2,3,4,5

X3 = 2,4,6,8,10

The figure:

The code:

X1 = [1 5 10 15 20];
X2 = [1 2 3 4 5];
X3 = [2 4 6 8 10];
plot3(X1,X2,X3);

It’s helpful Thank you

[Ghufran Aldawood]

Glad I can help. Good luck!

[Asma A Bder Muhmed]

You too
