Hi All,
I am plotting some time series data. Where the times are specified in datetime format starting '01-Oct-2021' and ending '28-Feb-2023 23:54:59'. I would like to plot the data with specific labels on the x axis. The code I have at the moment is as follows:
plot(Time,Watts3Ph/1000,'color','r')
grid on
ylim([0 65]);
yticks([0:5:65]);
xlim([Time(1) Time(end)])
datetick('x','dd/mm/yy HH:MM','keeplimits','keepticks')
ax.FontSize = 16;
xlabel('Time','FontSize',20)
ylabel('Load Demand (kW)','FontSize',20)
title('Load Demand','FontSize',22)
legend('Heading','FontSize',16)
legend('Location','northeastoutside')
What I want to do is specfy x labels at '01-Oct-2021', '30-Nov-2021 23:59:59','28-Feb-2022 23:59:59','31-May-2022 23:59:59','31-Aug-2022 23:59:59', '30-Nov-2022 23:59:59','28-Feb-2023 23:54:59'
I would also like to add verticle dashed lines at each of those x axis dates. Is this possible???
Thanks

Use the xticks funtion to specify where to place the ticks.
Use xline with the same x values to add a vertical line at each location. You can specify the linestyle.
If your X values are already datetimes, you don't need to use dateticks. Instead, you would set the format using xtickformat.
