Plotting to test probability convergence

I have written code that rolls a 12 sided dice and I need to plot a convergence graph for the value being 8 or above. I do not know how to do this.

%% Twelve sided dice

x=linspace(1,100000,100000);

a=1;

b=12;

TS=(a-1)+randi(b-a+1,1,100000);

xbins=[1:12];

hist(TS,xbins);

axis tight;

xlabel('Result of throw');

ylabel('Frequency');

%%this is the part of the code that was written to plot the convergence diagram but I do not know what it plots.

plot(x,TS);

xlabel('Number of trials');

ylabel('Value output');

That shows you what to do.
