Read the table in as a table using readtable. You will want to make sure column 1 is read in as a datetime. This 'should' happen automatically, but may depend on your version of MATLAB. Once in MATLAB, you can just plot using the datetime variable as your x input. As a datetime, it will automatically show date and time.

You can use xtickformat function to modify the display format of the datetime values.

在 MATLAB Online 中打开

Try this syntax: stackedplot(___,'XVariable',xvar)

xlsx_name = 'C:\\Air Temperature\MQLoad (1).xlsx'
tab = readtable(xlsx_name);
stackedplot(tab,'XVariable','Var1')

If that doesn't work, please share your spreadsheet. You can attach it to your post using the paperclip icon.
