maybe it will work with some decent dates...

[francois-achache]

no, just change the last value 5 or null and that's work or not No choice I have to disabled this feature in my graph

[helgasoft]

endLabel displays the last value. If all values are null, then there is no label. Demo Code

[francois-achache]

yes for sure, but doesnt have to raise an error in jsconsole
