How can I get percentage data from time series object?

How can I get data(x, y) of every 10%(0%, 10%, 20%, 30% ...100%) plots from time series object?

100% is max value of y axis data.

________________________________

x = sin(x);
y = linspace(0,1*pi,1000);
data1 = timeseries(x,y)
 
data_max   = max(data1);
data_90per = data_max*0.9;

________________________________

I can't get x and y axis data of data_max and data_90per.

I wanna plot every 10% from time series object.

N = 1000 ;
x = linspace(0,2*pi,N) ;
y = sin(x) ;
p = 10:10:100 ;
for i = 1:length(p) 
    id = round(N*p(i)/100) ;
    plot(x(1:id),y(1:id))
    title(sprintf('percentage = %s',num2str(p(i))))
    drawnow
end
