i had some spherical particles which will be moving with time i had the velocity data but to plot contour i need to assign to grid how to do this

in home page there is an option called import data, after importing select 2 coulmns which are in b and c rows which are particle postions (x,y) with respect to time and keep the option column vectors in output type and generate it as script

Describe your data: which column is what and which column is your time//velocity//coordinates, etc or you have formulation to compute your velocity from your atatched data?

xx,yy are x and y locations and at the starting real time tells at what time step we are ,velocity components is not there in that data. i dont have any

Here is what i invented
clc,clear
A = readtable('ploc.txt');
A1 = A;
k = 1;
for i = 0:10
ii = (1:561) + 561*i;
A1(ii,:) = A(ii+k,:); % read only with numbers
k = k + 2;
end
A2 = table2array(A1); % convert table to array
A3 = zeros(length(A2),5);
for i = 1:length(A2)
A3(i,:) = str2num(A2{i}); % convert cell/str to number
end
cla
hold on
for i = 0:10
ii = (1:561) +i*561;
x = A3(ii,2);
y = A3(ii,3);
plot(x,y,'.r') % draw particles
pause(0.5)
end
hold off
