If you mean you want to have non numeric values for your markers on the scale,
then as far as i know that is not possible directly with the charts/graphs.
There are properties regarding the markers, but for me the Marker.Text property never does anything and the help seems to not have this option listed.
Perhaps someone has a suggestion on how to build this feature yourself,
but i presume it is involved.
Then I can not put this data in a XY graph as it is presented in the picture?
yes it is possible, because you can use timestamps for the x-axis which can be formatted as you suggested
will attach a snippet later
attach your actual .vi, but make sure it got proper default values for the date-array saved
