This question may be a bit vague but is there anyway to plot these droplets (i.e. the red dots) on a curved surface. All coordinates are in polar form but regarding the plotting surface I'm not sure if there's any way to change it. I have attached a picture of the plot and my code, if anyone is able to suggest any ideas it would be appreciated!
a='.txt';
load('MyColormaps.mat','mycmap');
for i=500
str=int2str(i);
stp= strcat(str,a);
stp
c=load(stp,'w+');
s=size(c)
s1=s(1,1)
s2=s(1,2)
%b=zeros(s1,s1);
b=zeros(500,500);
%S2=sqrt(s1);
%b=zeros(S2,S2);
for ii=1:s1
x(ii,1)=c(ii,1);
y(ii,1)=c(ii,2);
r(ii,1)=c(ii,3);
[radial,theta] = cart2pol(x,y);
end
k=0;
for j=1:s1
if(r(j)>=0.005)
k=k+1;
rnew(k,1)=r(j);
xnew(k,1)=x(j,1);
ynew(k,1)=y(j,1);
[radialnew,thetanew] = cart2pol(xnew,ynew);
end
end
S1=k
for l=1:S1
xo=xnew(l,1);
yo=ynew(l,1);
R=rnew(l,1);
[radialo,thetao] = cart2pol(xo,yo);
for m1=1:1000
m=m1*10/1000;
for n1=1:1000
n=n1*10/1000;
if(((radialo-m)^2+(thetao-n)^2)^0.5)<=R
b(m1,n1)=1;
end
end
end
l
end
figure(i);
bas=figure(i);
imagesc(b);
axis([0 1000 0 160]);
axis square;
colormap(jet);
set(bas,'Colormap',mycmap);
print ('-dtiffn',sprintf('%d.tif',bas));
close all;
end

What type of surface plot you are looking for, please see surf , any pictorial representation?

It is a 2D shape i.e. r, theta so I don't think surf will be correct to use

Hi,
As all the data are in the polar coordinates (i.e. r and theta) the best possible way to visually represent the data is using the “polarplot()” which is in the 2D form.
For more reference and enhancements please refer to the documentation of the "polarplot()" .
For customizing the plot please refer to the documentation link here.
