How to change time interval in timeseries plot?

Hi there,

I have timeseries dataset('Model_01') which need to plot in a timeseries. The values need to plot in 3 hours interval but the figure represents 1 hour interval. How can I change that into 3h intervals? Folllowing commands use for the plot.

% plot model data
ts_Model_01                    = timeseries(Model_01);
ts_Model_01.TimeInfo.Units     = 'hours';
ts_Model_01.TimeInfo.StartDate = {datestr(datenum(num2str(buoy_start_date),'yyyymmdd'))};  % Set start date.
ts_Model_01.TimeInfo.Format    = 'yyyy-mm-dd HH:MM';                                       % Set format for display on x-axis.
ts_Model_01.Time               = ts_Model_01.Time - ts_Model_01.Time(1);                   % Express time relative to the start date
        
colorstring_Model = 'k';
        
plot(ts_Model_01,'-','Color', colorstring_Model,'LineWidth',1.5)

Your help is much appreciated.

Hi,

Thank you for the answer.

But I didn't get the exact meaning of that.

Can you please explain it more?

To use Matlab effectively it's neccessary know how to find information in the documentation. That's an art in itself. I added another link to my answer. Spend some time with the examples.
