Scale plot of datetime x-axis

Hello MatLab-Friends,

I want to scale a graph in order to plot just a section of it and not the whole data with the whole time. The graph has a number on the y-axis (which is easy to scale with the ylim-funtion) and datetime on the x-axis(which is the problem). The format of the datetime is dd.MM.yyyy HH:mm:ss,SSSSSS (for example: 29.04.2020 16:39:57,593613). I tried to use the xlim-fuction in different ways but couldn t find the right solution...

Here is a part of my code.

subplot(4,1,4);plot(Time_FM4,DruckFM4_P6);
xlabel('Zeit'); ylabel('Druck in Pa');legend('Messpunkt 6','location','southwest'); ylim([100 200]); xlim(datetime([29.04.2020 16:48:43,452692 29.04.2020 16:48:51,053126]));
xl=xlim
grid on

Thank you in advance!

Cheers

Jason

datetime accepts a char array or a string. Write it like this

xlim(datetime(["29.04.2020 16:48:43,452692" "29.04.2020 16:48:43,452692"], 'InputFormat', 'dd.MM.yyyy HH:mm:ss,SSSSSS'))
