hi all
i'm totally new to aij and nabble...
have been climbing the learning curve helped by Dennis's tutorials and others

i am managing to get some semblance of the sort of output that I am hoping for but one thing that should be basic but i may be missing in settings is how to avoid the zigzag lines that i seem to be getting per the attached image where i switched on lines for series 2.  the lines appear no matter which series i go for in this case.

the data in the example is from a number of runs as my system collected data on and off during the night due to weather (this also resulted in "dupe" appearing in filenames).  i would have thought that the software would have ranked the data entries by date/time rather than anything else but i think that this may not be happening.

am i missing some basic way to avoid this (without having to get into changing the naming convention of ACP data collection software would be ideal...)?

thanks
gavin
i hope that the image works in this size.
may zoom up and add another
