we have requirement where we store annotations in database and restore it as per demand. everything is working fine, but when user changes the height of parallel channels.. there is no way for us to save it.. since highstock does seem to save it..
https://jsfiddle.net/qewhndbm/1/
steps to re-create
1. add parallel channel to the chart
2. save the chart in local storage using button.
3. click on run again so you will get blank chart.. now restore annotation.
4. select the annotation and using control button (middle bottom) change the height of channel make it wider of very narrow.
5. save again.. and restore again.. you will notice that height is not being saved..
is this bug or may be i am missing something ?
Thanks
