The documentation I have found on the forum is only about removing the NaN which is not my case.
Here, the missing days are added automatically...
I do not have any NaN in my time series as you can see on the screen shot. But matlab is still adding non existing days in the graph so that I have about 30 days a month I guess...
Any idea how I can remove these very annoying gaps? Thank you very much in advance.
