Hello,
I am not a pro using Highcharts but I have already been using it to display personnal sensors data and always ended up finding the solutions I was looking for.
I am currently creating a Web App gathering some of my thermometers data, and am trying to graph them on an unique yAxis like following :
You can see that all of the series don't line up to the end. Yet, if you look at the database where I get these datas, all the last timestamps are not distant from more than 60 seconds each :
Also, you can see on the first image's tooltip that the last point at 15.5 degrees doest not have the same timestamp as it is in the database (It is the MAC address ending with 6D).
The series are built like arrays of arrays : [[timestamp1, temperature1], [timestamp2, temperature2], ... , [timestampN, temperatureN]] and the xAxis is setted up to type : 'datetime'.
Also, as the publish rate of my sensors may not be exactly always the same, some series have more data points than others :

But anyway, I just would them all to sync on the xAxis instead of be placed by number of points on what seems to be the "xAxis of the longest serie".
Thanks a lot for reading, and by advance, thanks for the help !
