As per my understanding, you are trying to show the labels of axis containing "datetime" data in "French" language. There is no direct way to achieve the objective, but I found few workarounds which may help to resolve your question.
1) You can change the output dates to any user-preferred Locale
use Locale option from preferences (Preferences -> Command Window -> Datetime format -> Locale). If you can not see a particular Locale in a drop down menu, just type in there and apply the changes. It will accept it if you type in correctly. For example, if you want the output to be displayed in French, type the Locale as "fr_FR" and apply the changes. You will observe the output from "datetime" function displayed in German
2) You can use "cellstr" function to specify the "locale" property as demonstrated below:
%C = cellstr(D,'fmt',"fr_FR") %fmt = output format of datetime object (D)
Refer to the documentation to find more information about the function:
I have also illustrated its use by a small example as shown below:
%create an array of datetime object for demonstration purpose
year=2024+ones(1,6);
month= [1 2 3 4 5 6];
day=13+ones (1,6);
datearr =datetime(year, month, day)
C=cellstr(datearr,'MMM d, yyyy',"fr_FR") %you can specify any datetime format "fmt". Here, it is 'MMM d, yyyy'
%create data for y-axis (for demonstration)
y_data=[1 2 3 4 5 6];
A=plot(datearr,y_data);
A.Parent.XTickLabel=C;
As seen, the xlabels are now appearing in French language. I hope this answers your question !
