"The trouble is that only where I am lacking in making code. "
I don't understand what you meant here.
"I want to define the parameters."
Which parameters?
"I want the following code for this purpose."
Which purpose?

Here are fixes for the first few lines so that dlmread works. But not sure what you are trying to do after that. Calling reshape with parameters of 500 and 500 means that the input vector must be 500*500=250000 in size.
% Assuming 'saveToFile' is already defined
parts = 500;
% Read data from the CSV file
data = dlmread('2-2.csv', ',', 0, 0);
%l = data(:, 1);
%alpha = data(:, 2);
%times = data(:, 3);
%ani = data(:, 4);
Var1 = data(:, 1);
Var2 = data(:, 2);
Var3 = data(:, 3);
Var4 = data(:, 4);

You are displaying the output as if you had a grid that is l in one direction and alpha in the other direction. But you do not have such a grid: you have vectors l and alpha and timeGrid that are all the same length. l and alpha are each equally spaced.
The best you can do is something like
plot(l, timeGrid);
