4D surface plot

Dear, could someone help me, please?

I have a file with n-lines and 4 column, where the column 1, 2 and 3 are positions and 4 column is temperature.

I would like plot a graphic 4D surface, where the axis x, y and z are the column from 1 to 3, respectively, and the color code is the column 4.

I tried do it using mesh or surf, but the axis-z doesn't is a function.

Below is my algorithm

clc,clear all,format long

point = load ('general_resultosA.dat') ; % load data

long = point(:,1); % longitude data

lat = point(:,2); % latitude data

rural = point(:,3); % percent rural data

fatalities = point(:,4); % fatalities data

xlabel('\Phi [deg]')

ylabel('\mu [adim]')

zlabel('k')

xlim([0 75])

ylim([0.5 0.9])

zlim([1 9])

mesh(long,lat,rural,fatalities);

This comand show a error:

"Error using mesh (line 71)

Z must be a matrix, not a scalar or vector."

You have scattered not gridded data. Have a look at this:
