Hi,
In this case, use one of these data import options:
(1) data import using uiimport('DATA_file_name.txt') that creates a table variable containing two column of data, viz date and values
(2) data import using importdata('DATA_file_name.txt') that creates structure type of data containing dates and data values.
(3) data import: textscan() ==> FID= fopen('DATA_file_name.txt'); DATA = textscan(FID, '%s %f'); fclose(FID);
The dates can be read with the command datenum(), e.g.,: DD = datenum('2019-12-30T01:15:14', 'yyyy-mm-ddTHH:MM:SSZ')
To plot the imported dates and data values: plot(DD, Values)
xlabels of dates can be displayed with datetick()
Good luck.
