Ran in:
Based on the below data, how can I create a surface plot with a colorbar for the response given data below: Hoping for your kind help!
A=[195 65 195 65 195 65 195 65]; %parameter 1
B=[120 120 150 150 120 120 150 150]; %parameter 2
C=[2 2 2 2 1 1 1 1]; %parameter 3
Y=[527 570 537 549 728 780 725 748]; %response
I have made a code below that represents a scatter plot, however, I wanted to know how I can do a surface plot with the response represented in the colorbar. Hoping for someone's help.
clc;
close all;
A=[195 65 195 65 195 65 195 65]; %parameter 1
B=[120 120 150 150 120 120 150 150]; %parameter 2
C=[2 2 2 2 1 1 1 1]; %parameter 3
Y=[527 570 537 549 728 780 725 748]; %response
scatter3(A,B,C,8,Y,'filled') % draw the scatter plot
ax = gca;
ax.XDir = 'reverse';
view(-31,14)
xlabel('Parameter 1')
ylabel('Parameter 2')
zlabel('Parameter 3')
cb = colorbar; % create and label the colorbar
cb.Label.String = 'Response';

You are trying to represent 4 dimensions which you can do in 3 spatial dimensions, and the fourth dimension colour. If you wanted it to be more like a surface plot it would have to be a cube of continuous colour changes which is impossible to see.
I would recommend breaking the data up into two surface plots and using:
