I am attaching my code.

% x coordinate data
temp1=350:390;
% y coordinate data
rad1=.001:.001:.02;
% z coordinate data (for this i have attached PPDF.csv file.)
test = csvread('PPDF.csv');   
% x=test(:,1);
% y=test(:,2);
% z=test(:,3);
[r, t] = meshgrid(rad1, temp1);
figure
scatter3(t(:), r(:), test(:),'filled')

PPDF.csv

You'll have to figure out how you want to rescale the data to fit standard data range for a color table, but you can do something like this:

% x coordinate data

temp1=350:390;

% y coordinate data

rad1=.001:.001:.02;

% z coordinate data (for this i have attached PPDF.csv file.)

test = csvread('PPDF.csv');

[r, t] = meshgrid(rad1, temp1);

% create some sort of color map

cmap = [rescale(test(:)),rescale(r(:)),rescale(t(:))];

scatter3(t(:), r(:), test(:),10,cmap,'filled')
