Hello, Only a single horizontal line is possible. gridDefault is default of off, which is translated as a Y-line at 0.0 yLineMark can be used to set an alternate Y line value yLineOnOff sets whether or not to look at yLineMark
Thank you for pointing out that this is missing from our documentation. The variable is in the track lines for examples, but never explained, we will work on correcting that. From doing a search against the mailing list archives, I was able to find several examples about how other users configured these variables for different purposes. You may find it interesting to review these.
