If ‘x’ is a datetime array, the arguments to xlim must also be datetime values —

x = datetime('now')+days(0:60);

y = sin(2*pi*5*(0:numel(x)-1)/numel(x));

xlim([datetime('12-Apr-2022') datetime('12-May-2022')])

When I am plotting the date from 24-Mar-2013 to 29-Nov-2021, I am only seeing year on the axis not the month, why is that?

Can you please explain?

These are the data and month I would like to plot

That would be the default for the x-tick choice and labels.

Using my previous code as an example, see if something like this would work:

x = datetime('now')+days(0:60);

y = sin(2*pi*5*(0:numel(x)-1)/numel(x));

figure

plot(x,y)

grid

title('Original')

figure

plot(x,y)

grid

xlim([datetime('12-Apr-2022') datetime('12-May-2022')])

title('With ‘xlim’')

xtv = min(xlim) : days(3) : max(xlim); % Define X-Tick Locations

set(gca,'XTick',xtv) % Set X-Tick Values

xtickformat('dd-MMM-yyyy') % Define X-Tick Format

Experiment with this approach to get the desired result.

plot(DeciYear, Mean_Surface_REF(:,bands) ,'LineStyle','None','Color',colors{bands},'MarkerSize',13,'Marker','o','MarkerFaceColor',colors{bands}); %plot lines

xlabel('Years','FontSize',16,'FontWeight','bold', 'Color','k')

ylabel('Surface Reflectance','FontSize',16,'FontWeight','bold','Color','k')

title(['Surface Reflectance for Band', num2str(bands),':',A{bands}],'FontSize',16,'FontWeight','bold')

xlim([datetime('24-Mar-2013') datetime('29-Nov-2021')]);

ylim([0.3 0.7]);

xtv = min(xlim) : days(3) : max(xlim);

set(gca,'XTick',xtv);

xtickformat('dd-MMM-yyyy')

%set(gca, 'FontSize', 16, 'Fontweight','bold');

grid on;

grid minor;

set (gcf,'color','white');

Using above technique I could not see the month and year in above chart,

Have i made any mistake?

My code is simply an example. It will likely be necessary to change it to produce the result you want. You will have to experiment with it.

You might want something like this:

xtv = min(xlim) : calmonths(1) : max(xlim);

The ‘step’ value (here ‘calmonths(1)’) controls the tick spacing.

x = datetime('now')+days(0:92);

y = sin(2*pi*5*(0:numel(x)-1)/numel(x));

plot(x,y)

plot(x,y)

xlim([datetime('12-Apr-2022') datetime('12-Jun-2022')])

xtv = min(xlim) : calmonths(1) : max(xlim); % Define X-Tick Locations

set(gca,'XTick',xtv) % Set X-Tick Values

xtickformat('dd-MMM-yyyy') % Define X-Tick Format
