hi

when i plot my series, the chart starts with a date and ends with another which are not held in my raw data thus creating empty spaces on the chart.

to clarify: the start date from my data is 3/3/2003 and ends at 1/26/2015. however from my below script , matlab outputs a chart starting on 01-01-2000 ending on 01-01-2020 for some reasons. Hence blank spaces are displayed on the chart from 01-01-2000 to 3-3-2003 and from 1-26-2015 to 01-01-2020.

for curiousity does someone know why matlab adds automatically 01-01-2000 && 01-01-2020 to the chart? is there a way of limiting the x-axis to my time series date so as to improve the quality of the chart? i've already tried

axis([-10 10 0 inf])

without any improvement. cheers

  t_=x(:,1);
  t_x=cellfun(@datenum,x(:,1));
  px_=x(:,2);
  px_x=cell2mat(x(:,2));
  rt_=x(:,3);
  rt_x=cell2mat(x(:,3));
subplot(2,2,1);
plot(t_x,px_x),datetick('x','dd/mm/yyyy'),xlabel('date'),ylabel('price'),title('x');
subplot(2,2,2);
plot(t_x,rt_x),datetick('x','dd/mm/yyyy'),xlabel('date'),ylabel('return'),title('y');

Cheers Guillaume, it does improve the chart's quality. the main drawback as far as i am concerned: it removes any date from the x-axis. Thus do you have any idea on the way to divide the x-axis into few segments and see them displayed in the chart?
