Does not plot all the points

So I am trying to plot a lot of data (5779x5779), but looks like the graph only takes few points. Does someone knows why is this happening?

code:plot(s3,x5mV)

It should look like this:

(1) Use function scatter instead of plot

(2) Some of the header or some other information were saved in the mat file ( I guess from #5723).

load('variable_5V.mat');
load('variable_s3.mat');
s=scatter(s3(1:5722),x5mV(1:5722),2);           % I select the first 5722 data only
grid on;
