how do i use datetime adjust xtick

when i useing datetime plot timeseries

i want adjust year by year xtick

ex. 2007 2008 2009 2010 2011 ... 2022

Is there any way to adjust xtick besides using datetick\

clear all ; clc ; clf

load data_1206_wl_max.mat

all_time_1206 = datetime(all_time_outliner_1206 ,'ConvertFrom','datenum'); %% x

plot( all_time_1206 , all_tide_outliner_1206,'k' );hold on

% datetick('x','yyyy')

this pictuer not using datetick

xtick is 2008 2010 2012 2014 ... 2020

i want get to know if datetime can adjust xtick more freely

[Chunru]

datatick has a lot of options for changing the format of the xticks such as below. What additional customization doy you want?

datetick('x', 'mm/yyyy')

As per my understanding you want to know how to adjust xticks in datetime plot

I will try to explain it using an example below

startDate = datenum('01-01-2009');
endDate = datenum('12-31-2009');
xData = linspace(startDate,endDate,12)

xData = 1×12

1.0e+05 * 7.3377 7.3381 7.3384 7.3387 7.3391 7.3394 7.3397 7.3401 7.3404 7.3407 7.3410 7.3414

yData=rand(1,12)

yData = 1×12

0.8718 0.0657 0.8671 0.3537 0.9655 0.9012 0.9318 0.3869 0.1760 0.7679 0.0407 0.4823

plot(xData,yData)
ax = gca;
ax.XTick = xData;

Try the following without using the function datetick.

f = figure;
ax=gca;
plot(ax,all_time_1206 , all_tide_outliner_1206,'k' );
ax.XLim(2) = datetime(2022,1,1);                        % Set the limit to 1 Jan 2022
ax.XTick = ax.XLim(1):calyears(1):ax.XLim(2);           % Modify XTick based on the limits

I'd encourage you to follow @Simon Chan's advice to use datetime rather than datenum and datetick. With the recent R2022b release, datenum is not recommended.
