I'm able to draw a plot for out with size 100x11 using below code

x=0:0.1:1; plot(x, out(:,(x*10)+1),'ko');

But I'm unable to figure out how to draw jitter plot for that data.

Below is my complete Matlab code that I'm using to save data into the output variable and trying to plot the data of output using jitter plot.

clc;
close all;
clear all;

heads = 0;
flip_chance = 0.0;
weight = 0.0;
c = 2;
output = zeros(100,11);
for p = 0.1:0.1:1.0

    for i = 1:1:100

        heads = 0;
        flip_chance = 0.0;

        for j = 1:1:10
           weight = rand();
           flip_chance = (p*10)+weight;
           if flip_chance >= 0.5 && weight <= p
              heads = heads + 1; 
           end

        end
        %fprintf ("p : %f , heads : %d\n ", c, heads);
        output(i, c) = heads;

    end
     c = c+1;
end
x=0:0.1:1;
plot(x, output(:,(x*10)+1),'ko');

When I run with the plot I'm getting below output

I trying to get the plot in the below format

  • This question is now substantially different from the one that I answered. Please avoid changing the question. Adding clarifications like the second graph you posted is OK, but You should post a new question about changing intervals. – Cris Luengo Mar 03 '18 at 15:44
  • The extent of the data plotted is adjusted with the `XLim` property: `set(gca,'XLim',[-0.1,1.1])`. – Cris Luengo Mar 03 '18 at 15:49
  • sorry for changing the question, changed it back. Thanks for your help. –  Mar 03 '18 at 15:51

A jitter plot is imply a scatter plot like you make but with some noise added to the location of each dot. You can for example use the following code:

sz = size(output);
x = repmat(linspace(0,1,sz(2)),sz(1),1);
plot(x+0.06*rand(sz),output+0.6*rand(sz),'k.')

I'm using x+0.06*rand(sz) because x has increments of 0.1, so this gives a dot spread of 60% of the dot spacing along the x axis. You can change the 0.06 to suit your tastes. The same with output+0.6*rand(sz): 0.6 is 60% of the spacing.

EDIT

The "goal" graph you posted uses jitter only in the y axis. You'd leave out the random value added to x to accomplish this. It also seems to use a lot of jitter, merging visually the points for different y-groups. You'd set the random multiplier to at least 1 for such a graph, but I don't recommend it.
